Choosing and setting a welding mask for TIG
Updated: October 2026
Your helmet darkens reliably on MIG, yet flickers pale when you run a neat bead on thin steel. That does not necessarily mean your TIG technique is wrong. A welding mask for TIG must detect a comparatively small, steady arc and remain dark when the torch, filler hand or workpiece partly obscures its sensors. Start with high sensitivity, a longer delay and clean sensors. If the lens still opens, stop using that helmet at the current. The [welding mask comparison](/hub/soldering-and-welding/welding-mask) lists twelve amazon.co.uk models, and none states a minimum TIG amperage. We did not lab-test these filters.

Why TIG can flash a mask that works on MIG
MIG produces a bright, active arc that is usually easy for light sensors to recognise. Smooth low-current DC TIG can present a weaker and more constant signal, especially in a well-lit workshop. A budget filter may drop back towards its light state because it no longer interprets that signal as an arc. The result is often described as flicker or flashing.
Obstruction makes the problem worse. Your torch angle, filler hand or a corner of the workpiece may hide one sensor. A four-sensor helmet can provide more sight lines than a two-sensor design, but sensor count is only one part of the circuit. TOOLIOM states four sensors, while YESWELDER and several others state two. Neither listing gives a verified minimum TIG current. Forum accounts describe helmets working on stick or pulse but opening on smooth DC TIG. Pulse can produce a more obvious changing light signal, which is why some welders find it masks the problem. That is a workaround people report, not a requirement for TIG and not a reason to alter a sound procedure merely to satisfy an unsuitable helmet.
Sensitivity high, delay long
Begin in weld mode, not grind. Raise sensitivity so the filter responds to the smaller arc, then lengthen delay so a brief obstruction does not immediately return it to the pale state. Clean the outer cover and sensor windows, make sure they face the work and check the battery according to the manual. The full control order is in the how to use a welding mask guide.
Shade is a separate setting. A UK supplier chart suggests around shade 9 for TIG at 20–40 A and around shade 10 at 40–100 A. Treat these as starting guidance and begin darker when uncertain. Turning the filter to shade 13 does not make the sensors more sensitive. It can simply hide the pool once the filter has darkened. Try the settings once using the manufacturer’s prescribed checks. If the lens opens for seconds during a stable arc, stop. Repeating the arc to experiment exposes you again without proving that the next attempt will latch. A fresh cover may help dirty optics. Adjustments cannot create low-current performance that the filter lacks.
What these listings actually state
YESWELDER LYG-L600A costs about £37.04 and states shades 4/9–13, two sensors, true colour and 1/1/1/2 optical figures. The process list names TIG. It still does not state whether the filter triggers at 2 A, 5 A or any other minimum, and its listed weight conflicts between 500 g and 950 g.
TOOLIOM TL-31800H costs about £54.14 and states four sensors, 1/1/1/2 optics, a 3.94 x 3.66-inch window and shades 4/5–9/9–13. Those details make it the strongest paper specification for sensor coverage and view in this set. Four sensors do not guarantee low-amp TIG, and one review reports an early headband failure. Its listed 1.04 kg weight also makes fit important. HITBOX HT111 lists shades 4/5–9/9–13 and a true-colour view for about £24.99, with no sensor count or viewing dimensions. The two £26.99 HITBOX artworks give a 3.54 x 1.57-inch window and again no sensor count. DEKO names TIG and gives 1/2/1/2 optics, yet its main bullets do not state the numerical shade range. Missing and conflicting fields are set out in the welding mask buying guide. One DEKO review describes acceptable aluminium TIG but weaker results on mild steel in lower light. That is one experience, not a model rule.
What true colour and optical digits can tell you
True colour may make the joint and pool easier to distinguish than a strong blue-green tint. It does not tell you the trigger threshold. LESOLEIL describes a blue-green view, while YESWELDER and TOOLIOM claim true colour. Either filter still needs to remain dark throughout the arc.
Optical figures describe image and shade qualities under the older EN 379 scheme, with 1 the tighter class in each position. A stated 1/1/1/2 can support a clearer, more even view than 1/2/1/2 on paper. It is not a low-amp sensitivity number. A standards line does not fill in a missing minimum current. The useful buying evidence is a stated shade range, adjustable sensitivity and delay, sensor coverage, replaceable covers, power you can maintain and reviews that do not report opening during the intended work. The word TIG in a title is only the beginning.
When to quit on that helmet
Stop when the filter repeatedly opens during a stable arc after you have confirmed weld mode, high sensitivity, longer delay, clean sensors, a sound cover and adequate power. Return or replace the unit rather than normalising flashes. If the manufacturer specifies a minimum current above your work, choose a filter designed for the lower range.
Also stop if the shell is cracked, the cover is loose or light can enter around the filter. These are physical faults, not sensitivity problems. A darker setting cannot repair a gap. Conditional picks are on the best welding mask page, and none should be used when damaged. Arc-eye symptoms can be delayed by six to twelve hours. Pain, watering and light sensitivity after a flash are reasons to seek clinical advice, with urgent help if pain worsens or vision changes. Do not conduct another live test while waiting to see whether symptoms develop.
Common questions
Why does my helmet flicker only on DC TIG?
Smooth low-current DC TIG may provide a weaker, steadier light signal than MIG or pulse. The filter can lose its trigger if sensitivity is too low, a sensor is obscured or the helmet simply cannot detect that current reliably.
Should TIG sensitivity be high or low?
Start high for a small TIG arc, then reduce it only if ambient light or nearby welding causes false triggering. Sensitivity affects detection. It does not replace the correct shade.
What delay should I use?
Use a longer delay when the filter opens during momentary obstructions or while the pool remains bright. Exact scales differ, so follow your manual rather than copying another helmet’s knob position.
Is shade 13 safer for thin TIG?
Not automatically. Shade 13 may make a low-current pool impossible to see and does not improve sensor detection. Use process-and-current guidance, begin darker, then adjust cautiously until the pool is visible.
Do four sensors solve low-amp TIG?
No. Four sensors can reduce blind spots, but filter electronics and trigger threshold still matter. TOOLIOM states four sensors but no minimum TIG amperage.
Which masks here state a TIG minimum current?
None of the twelve listings states one. Suitable for TIG therefore remains a general use claim, not proof of reliable operation at 2 A, 5 A or another low value.
When should I replace the helmet?
Replace or return it if it repeatedly flashes after correct setup, will not darken with sound power, or has a cracked shell, loose filter or light gap. Those are stop conditions, not tuning problems.
