Plasma cutter consumables: nozzles, tips, and wear

Your plasma cutter consumables have already failed if the hole in the tip is no longer a circle and the electrode behind it has a pit you can catch with a fingernail. On the amazon.co.uk cutters in this comparison the torch is a PT31, an AG60, a P80 or a PT40, and a spare for the wrong name will not seat. Figures below are listing lines and reviews from that file, read in October 2026. A 23-piece tip kit is a bag of spares, not one of the eleven cutters. Products Compared did not time a nozzle in a lab.

In short

Match the spare to the torch name on your listing: PT31, AG60, P80 or PT40. Only the touch-start SPRIGHOLLY CUT60 and the CUT60L PRO print a post-flow time, and that time is 2 to 15 seconds. A claim of 50% longer consumable life on the Reboot 45 A listing has no hours attached. No review in this set gives a measured life.

The parts that wear

The nozzle is the copper tip, and the orifice is the hole the air jet leaves through. When that hole opens out or goes oval, the cut widens and the arc stops tracking the line. The electrode sits behind the nozzle and takes the arc. The cup holds both. A swirl ring or an O-ring may appear in a manual you already own. The listings do not name them. The torch family is a fit, not a rank. A hyphen, as in PT-31 or AG-60, is how two of the bullets spell the same families.

The plasma cutter comparison is where these names come from. Eleven single-phase air plasma cutters on amazon.co.uk sit under a Stahlwerk search, with SPRIGHOLLY, Reboot, PLASMARGON, Haxiaoer and SUSEMSE on the boxes. Stahlwerk's own catalogue is a different set of machines. If the stamp on the cup disagrees with the listing, trust the cup you can read.

Which torch name is in which box

PT31 consumables belong to four listings. The Haxiaoer HXC600D names a PT31 cutting torch. The touch-start SPRIGHOLLY CUT60 names a PT-31 torch with a 3 m cable, and a bullet mentions a roller guide. The Reboot CUT60 names a PT31 torch with an extra roller, part number PT31, and the included list adds a PT31 consumables kit. The SUSEMSE LT55 names a PT31 consumables kit with a 2.5 m torch. An AG60 tip is the wrong spare for all of them.

AG60 plasma tips belong to a different group. The SPRIGHOLLY CUT50L lists an AG60 torch with a 4 m cable and two nozzles and two electrodes. The SPRIGHOLLY CUT60L PRO lists an AG-60 torch, again with two electrodes and two nozzles. The PLASMARGON PLC65 lists a standard AG60 consumables kit. The Reboot 45 A part number field says AG60. The Reboot CUT60 is the PT31 machine. Ordering "Reboot tips" without the family is how a spare arrives that will not screw in.

P80 plasma torch consumables appear once. The PLASMARGON CUT65 Pro lists a P80 non-touch pilot-arc torch with a 2.5 m cable, plus electrodes and nozzles and no count. PT40 appears once, on the Reboot non-HF 40 A, model RBC4000LF, part number RB-PT-40, with a consumables kit. The PLASMARGON CUT55 included line says only "plasma torch". A warranty sentence on that listing uses the name PLC55 while the model line says CUT55. Neither line gives PT31, AG60, P80 or PT40. Leave that torch unmatched until you can read the cup or the manual.

Amps do not select the tip. The PLC65, at £129.99, is an AG60 kit. The CUT65 Pro, at £139.99, is a P80. The CUT50L, at £67.83, is 50 A and AG60. The non-HF Reboot, at £199.00, is 15–40 A and PT40. Current and family travel separately on these pages.

What shortens their life

Dragging is the fast way to ruin a nozzle. Sit the bare tip on the steel and slide, and the orifice melts out of round. Two listings name a roller: the SPRIGHOLLY CUT60 bullet mentions a roller guide, and the Reboot CUT60 includes an extra roller. A drag shield is not printed across this set. If your cup has no shield, keep the bare nozzle off the surface.

Wet air is the second spend. The touch-start CUT60 and the CUT60L PRO describe a filter and regulator as built in. The CUT65 Pro lists an air-filter regulator. The Haxiaoer lists a hose and filter. The Reboot 45 A describes a regulator as pre-installed, and the non-HF 40 A describes a pre-installed pressure reducer. A regulator sets pressure. It does not dry a tank you have never drained. Every cutter here needs that outside compressor: a plasma cutter when you have no compressor. Drain the tank before a session. The CUT50L spare line does not name a filter, so drying still starts at the compressor, at the 90 PSI and 60 L/min the bullet asks for.

Piercing spends tips because molten metal blows back at the orifice. A SUSEMSE review says piercing 4 mm wall box section used a lot of consumables, and it gives no hours. The listing prints a 10 mm clean cut and a 12 mm severance. An edge start on thinner sheet avoids that blow-back. A UK review of the touch-start SPRIGHOLLY CUT60 says paint has to be cleared so the arc has a path to the tip. Scratching that path with the nozzle marks the orifice before the cut starts. A pilot arc still burns a pitted electrode.

When you swap, unplug the cutter, shut the air off, let the torch cool, and unscrew the cup. Change the nozzle and the electrode together once the orifice is no longer round. These listings print no torque. If the manual in your box shows a different order, that manual wins. How to use a plasma cutter covers the first hour, including the moment the arc dies and the torch starts to consume itself.

Post-flow, only where a time is printed

Plasma cutter post flow is air that keeps moving after you release the trigger, so the nozzle and electrode cool. R-Tech Welding's UK how-to describes that cooling air after the arc. The touch-start SPRIGHOLLY CUT60 says post-flow cooling is adjustable from 2 to 15 seconds. The SPRIGHOLLY CUT60L PRO says adjustable post-flow and pilot-arc time, both from 2 to 15 seconds. Those are different timers on one bullet.

The other nine listings do not print a post-flow second: the CUT50L, the Reboot CUT60, the Reboot 45 A, the Reboot non-HF 40 A, the PLASMARGON CUT55, the PLC65, the CUT65 Pro, the Haxiaoer and the SUSEMSE. If your panel has a knob, the manual in that box sets the range. Leave the air on until the torch has finished its blow.

Spares in the box, and a percentage to leave alone

Counted spares are the exception. The SPRIGHOLLY CUT50L lists two nozzles and two electrodes with the AG60 torch. The CUT60L PRO lists two electrodes and two nozzles with the AG-60 torch. Changed as a pair, that is one swap and one spare left in the bag. The CUT50L is at £67.83, and the file has set no badge on it. The amazon.co.uk line is 5.0 from 2 reviews, which cannot tell you how many metres those two tips will cut.

Other boxes name a kit and print no count. The SUSEMSE LT55 and the Reboot CUT60 say a PT31 consumables kit. The PLC65 says a standard AG60 consumables kit. The Reboot 45 A says a consumable set. The Reboot non-HF 40 A says a consumables kit with the PT40 torch. The CUT65 Pro says electrodes and nozzles. The Haxiaoer and the touch-start CUT60 name the PT31 torch without a spare count. Open the bag and count the nozzles before you pierce.

The Reboot 45 A listing claims 50% longer consumable life. A review on that listing says the consumables lasted longer, and it gives no percentage and no hours. No review in this set states a measured life in hours. Plan the spare from the torch name and from how you cut: dry air, a tip held off the plate, and fewer pierces on thick wall.
