The best welding magnets, compared.
Top pick: YESWELDER KY1101-50lb-EU Best value: S&R 290.803.000 – Seven stated angles, including 15°, 60°, 120°, and 165°, at about £11.95 for two holders. Updated October 2026.
A welding magnet holds mild steel at a preset angle while you tack, mark out, or fit a short pipe. It is not a welder, and it is not a magnetic ground clamp. These ten amazon.co.uk listings cover fixed arrows, a multi-angle pair, a six-piece set, and one switchable holder. Most arrows offer only 45°, 90°, and 135°. Paint, rust, filings, thin sheet, and a long tube all reduce the hold. A stated pull is the seller's figure on clean thick mild steel, not the weight of the workpiece. The buyers are mostly home fabricators who want a four-piece arrow at 45°, 90°, and 135°. Austenitic stainless such as 304 and 316, aluminium, brass, and copper do not. Tec Products says so, and gripper table puts austenitic stainless at zero. How to choose is set out in the [welding magnet buying guide](/hub/soldering-and-welding/welding-magnet/sub/welding-magnet-buying-guide).

Personal buying guide
Question 1 of 2
What are you holding?
The YESWELDER 50 lb pack offers four fixed arrows at 45°, 90° and 135° for £11.98, which is an unusually low price for the stated pull. Its listing shows 4.6 stars from 845 amazon.co.uk reviews, but that review text, star line and sales rank are identical to the brand's 25 lb listing. You therefore cannot use those reviews as independent evidence that this heavier model delivers a 50 lb hold. The pack weighs 1.67 kg in the catalogue and is aimed at light plate and frame positioning rather than lifting. Shared review notes mention light plate and tube, but they cannot safely be assigned to this model alone. It remains attractive on specification and price, with a material evidence caveat that keeps it behind the top pick.
Pros
Cons
Best for: Supported mild-steel work where you want a higher stated pull at a low price and accept the review caveat.
Less suitable: Buyers who need independently attributable reviews or a measured lifting capacity.

Common questions
What angles does the listing state?
The listing states 45°, 90°, and 135°.

The YESWELDER 25 lb set gives you four fixed arrows for the standard 45°, 90° and 135° positions. Its 520 g catalogue weight and up-to-25 lb claim distinguish it from the brand's heavier 50 lb listing, but the two pages share identical UK review text, rating and sales rank. The displayed 4.6 stars from 845 amazon.co.uk reviews must therefore be treated as a combined listing signal rather than model-specific proof. Shared owner comments refer to light plate, tube up to about 5 mm and using clamps when the magnets cannot cope. At £14.24, it costs more than the clearer AB Tools 25 lb four-pack in this comparison. It can serve as a normal bench set, but the review collision and price weaken its value case.
Pros
Cons
Best for: Supported light plate and short tube where a conventional 25 lb four-pack is enough.
Less suitable: Buyers seeking model-specific review evidence or the lowest-priced 25 lb option.

The AB Tools four-pack gives a home fabricator four 25 lb arrow holders for supported light frames and square corners. Each arrow offers 45°, 90° and 135°, while the roughly 120 x 83 mm body provides more contact area than a mini holder. Its 4.5-star average from 1,133 amazon.co.uk reviews is backed by a substantial review base, and the £11.03 price is competitive within this comparison. The stated pull still assumes favourable contact with clean mild steel: owner evidence says a metre of 50 x 50 x 3 mm box section can overwhelm it. This means it works best as an extra hand while the bench or another support carries most of the load. It is our top pick for ordinary supported light-steel fabrication, but not for suspending long stock.
Pros
Cons
Best for: Supported light mild-steel frames, sheet and short box section on a flat bench.
Less suitable: Long rails, upright heavy stock or unsupported structural work.

The four Neilsen mini holders give you several small contact points for light mild-steel edges at 45°, 90° or 135°. Their stated pull is only 10 lb, so this is a positioning set rather than a substitute for a clamp on long or upright stock. A review reports that roughly 500 mm of 3 mm steel was already too much for the hold, which is the practical limit to notice despite the large review count. The 4.4-star average from 1,779 amazon.co.uk reviews is reassuring for a cheap accessory, but it does not make the magnets stronger. The £7.89 price suits occasional tinplate, tabs and compact bench work. Catalogue dimensions and the included-components line conflict with the four-piece title, so the listing is less tidy than the headline suggests.
Pros
Cons
Best for: Small tabs, tinplate and short mild-steel pieces supported on a bench.
Less suitable: Long 3 mm plate, box section or work that must support its own weight.

The Spurtar pack supplies six fixed arrows, enough to position several corners before tacking. They use the familiar 45°, 90° and 135° faces, and the listing shows 4.4 stars from 390 amazon.co.uk reviews. The holding specification is unclear: the title says 13 kg while the catalogue says 25 lb, figures that should not be treated as interchangeable. An owner also reports that 25 mm box section fell, which underlines how contact, support and leverage matter more than the headline pull. At £16.19, this is the most expensive fixed multi-pack in the comparison. The extra two pieces are useful for batch assembly, but the specification conflict and reported slip stop it being a default recommendation.
Pros
Cons
Best for: Several small supported joints where six contact points are more useful than maximum pull.
Less suitable: Unsupported box section or buyers who need an unambiguous force rating.

The S&R pair is the useful alternative when a standard three-angle arrow will not match the joint. Between the two holders it covers 15°, 45°, 60°, 90°, 120°, 135° and 165°, with stated forces of 9 kg and 13 kg. At £11.95, that range costs little more than a conventional four-pack, although you receive only two holders. The 4.4-star average comes from 178 amazon.co.uk reviews, a smaller evidence base than the leading arrow sets. One owner found the pair useful on pipe, while another reported that 1-inch box section at 1.5 mm would not remain square on a table. The bullet dimensions and catalogue dimensions also disagree, so buy it for angle choice rather than a precise published size.
Pros
Cons
Best for: Supported mild-steel joints that need 15°, 60°, 120° or 165° as well as common angles.
Less suitable: Four-corner assemblies or jobs where exact catalogue dimensions matter.

The QWORK WD6028 spreads six holders across angles from 30° to 135°, making it more flexible than a pack of identical arrows. Its stated range of roughly 15 lb to 25 lb is adequate for positioning supported light mild steel, though owner reports include complaints that the magnets feel weak. At £13.99, you get the largest piece count in the comparison without moving into premium pricing. The 4.4-star average from 173 amazon.co.uk reviews is useful but not conclusive for every holder size in the mixed set. There is no on/off switch, so six fixed magnets also mean more faces that can collect swarf. Choose it for angle coverage and multiple small joints, not because every piece matches a full-size 25 lb arrow.
Pros
Cons
Best for: Multi-angle layouts, repeated small joints and supported light-gauge fabrication.
Less suitable: Long heavy box section or buyers expecting six full-strength 25 lb holders.

The QWORK WD6418-N supplies four conventional arrow magnets for tacking mild steel at 45°, 90° and 135°. Its seller-stated 28 lb, or 12.5 kg, pull places it just above the common 25 lb class on paper, but that is not a measured guarantee on thin, rusty or rounded stock. The £11.98 price is sensible for a four-pack, and the 4.3-star average is based on 93 amazon.co.uk reviews. That review base is much thinner than the AB Tools or Neilsen sets, so the score deserves less confidence. The fixed magnets have no switch and will pick up filings during normal bench use. This is a plausible general-purpose set if the price holds, though the evidence does not justify calling it stronger in practice than every 25 lb arrow.
Pros
Cons
Best for: Occasional supported mild-steel frames and bench tacking at common angles.
Less suitable: Buyers who need a switch, unusual angles or well-documented workpiece limits.

The Swpeet S3211 is a four-arrow set for 45°, 90° and 135° joints, with a £12.99 shelf price. Its title and pull-force field say 25 lb, which is the figure to use when comparing it with other arrows. A separate bullet mentions 25, 50 and 75 lb without explaining which figure applies, so the listing does not support treating this pack as a 50 lb or 75 lb set. The 4.3-star average is based on only 33 amazon.co.uk reviews, the smallest review count in this comparison. The model line also says S3211 while the manufacturer part line says S3212. It may handle ordinary supported tacking, but the catalogue conflicts make clearer 25 lb alternatives easier to recommend.
Pros
Cons
Best for: Light, supported mild-steel tacking when the 25 lb title specification is sufficient.
Less suitable: Anyone relying on a 50 lb or 75 lb claim, or wanting a well-verified listing.

The S&R 290.103.100 is the only switchable holder in this comparison, so you can position it while off and release filings more easily after use. It offers 45°, 90° and 135° faces with a stated 12 kg side force, but the switch is a handling feature rather than proof of a stronger hold. At £28.98 for one holder, it costs more than any fixed multi-pack here. The 3.5-star average from 195 amazon.co.uk ratings is supported by only three UK review texts in the available evidence; two say the body is large without feeling as strong as its size suggests. The catalogue also disagrees over whether the thickness is 1 cm or 3 cm. It suits frequent repositioning and cleaner release, but it is not the premium pick for holding force alone.
Pros
Cons
Best for: Frequent setup changes where easy placement, removal and cleaning justify the premium.
Less suitable: Budget four-corner work or anyone seeking the highest stated pull.

We compared 10 welding magnet listings on amazon.co.uk, using seller specifications, shelf prices, and UK review evidence captured on 16 October 2026. The score is an editorial comparison. It is not a measured pull test. Points come off for a thin review base, a review block shared across two models, conflicting force or size claims, and owner reports of slip on the work the listing appears to target. A high stated pull is not treated as performance on thin sheet, rust, paint, pipe, or long stock. Fixed magnets are not marked down only because they lack a switch. The weights below sum to 100.

Check the metal, then the stated pull, then the angles. A star rating does not tell you whether the face will hold rusty sheet, pipe, or a long tube.
A welding magnet is a permanent-magnet holder that keeps mild steel at a preset angle while you tack, solder, mark out, or fit small pipe. The buyers in this set are mostly home fabricators who want a four-piece arrow at 45°, 90°, and 135°. The metal has to be magnetic. Mild steel and iron hold. Austenitic stainless such as 304 and 316, aluminium, brass, and copper do not. Tec Products says so, and Goudsmit's gripper table puts austenitic stainless at zero.
The figure is a stated pull on clean thick mild steel. Paint, rust, an air gap, thin sheet, and a long tube all reduce it. Eclipse makes the same point for similar clamps: thickness, air gap, and heat matter.
The Neilsen CT1930 has 1,779 reviews and a stated pull of 10 lb. A review already found about 500 mm of 3 mm steel too much. The review count does not raise the pull.
Tack, then take the magnet off. Fixed faces also collect swarf, and a dirty face holds less on the next piece. None of these listings prints a maximum temperature.
Mild steel and iron hold. Austenitic stainless such as 304 and 316, aluminium, brass, and copper do not. That is the first filter, before any star rating. Stated pull in this set runs from 10 lb (about 4.5 kg) on the Neilsen minis, through 25 lb arrows (about 11.3 kg), to a seller figure of 50 lb (about 22.7 kg) on one YESWELDER pack and 12 kg on the S&R switch. Those numbers assume clean, thick, flat contact. They are not a hold on rusty sheet, pipe, or a vertical plate.
Most arrows offer only 45°, 90°, and 135°. The QWORK six-piece steps from 30° to 135° at a stated range of about 15 lb to 25 lb. On the same scale as 25 lb being about 11.3 kg, that range is about 6.8 kg to 11.3 kg. The S&R pair adds 15°, 60°, 120°, and 165° and gives you two holders, not four. A switch helps you place the magnet and wipe swarf. Only the S&R 290.103.100 has one here, at about £28.98, and owners question whether the body feels as strong as its size. Piece count comes last.
Three typical situations, each with a recommendation from this comparison.
You want four arrows for supported mild-steel corners at 45°, 90°, and 135°. The AB Tools AT847_4PK states 25 lb at about £11.03, with 4.5 from 1,133 reviews. A metre of 50 × 50 × 3 mm box can still overwhelm it, so the bench should carry the load.
You need 15°, 60°, 120°, or 165° as well as the usual faces. The S&R 290.803.000 pair states 9 kg and 13 kg at about £11.95, from 178 reviews. You get two holders, and the published dimensions conflict.
Peeling fixed magnets off the bench is the annoyance. The S&R 290.103.100 is the only switch here, at about £28.98 for one holder and a stated 12 kg side force. It shows 3.5 from 195 ratings. The lever is not a stronger hold.
For supported light mild-steel frames, the top pick is the AB Tools AT847_4PK at about £11.03: four arrows with a clear 25 lb specification, faces at 45°, 90°, and 135°, and 4.5 from 1,133 amazon.co.uk reviews. It is an extra hand while the bench carries the load, not a clamp for a metre of 3 mm box. For uncommon angles, the best value is the S&R 290.803.000 pair at about £11.95, covering 15° through 165° at 9 kg and 13 kg, with only two holders and a smaller review base. None of these scores is a laboratory ranking, and none of the sets is certified to a British Standard.
S&R 290.803.000
Seven stated angles, including 15°, 60°, 120°, and 165°, at about £11.95 for two holders.
