描述
A plasma cutter is only as good as the last inch of its torch, and that last inch is a consumable. The Consumable Set exists because of a specific and expensive habit in fabrication shops: replacing a whole torch body when the electrode has worn, or continuing to cut with a pitted nozzle until the kerf widens and the edge quality collapses. Both decisions cost more than the parts. This set covers the Powermax125 platform and its 45 to 65 amp siblings with the correct part numbers — nozzles, electrodes, shields, swirl rings and retaining caps — so the torch can be refreshed at the point of wear instead of being replaced wholesale.
The part numbering is the whole catalogue, and it is worth reading closely. The electrode is 220971. Nozzles 420158 for the 45 amp cut, 420169 for 65 amp, 220975 for 125 amp, with 420001 for gouging. Shields 420000, 420172, 420168, 220976, 420152, 420112 and 420519 map to drag-cutting, mechanised cutting and the two gouging profiles. Swirl rings arrive as 220997 and 420159. Retaining caps are 220977 standard and 420156 in the ohmic version used for sensing height control on a table. Matching the number to the job is what keeps the arc stable, the kerf narrow and the consumable life predictable.
Each part carries CE certification and is supplied in the pack sizes that match actual consumption: single pieces for trial and setup, five and ten piece packs for routine work, and twenty piece packs for shops running production hours where the torch is never cold. Stocked across nineteen variants in total, the set is built to be ordered once and drawn from, rather than ordered in a panic when the last nozzle gives out mid-job.
An arc is only as clean as the copper it leaves through. Replace the tip, not the torch.

Application Scenarios
The Consumable Set is aimed at the three places plasma consumables actually get used up. In a fabrication shop running a Powermax125 on a cutting table, the ohmic retaining cap and mechanised shields are the parts that fail first, and the 20 piece packs keep a production day from stalling. In a mobile welding rig or agricultural repair service, the 45 and 65 amp nozzles and drag shields carry the bulk of sheet and plate work, so the 5 and 10 piece packs are the practical size. For hobbyists and small workshops, single pieces and the FineCut consumables allow a specific profile to be tested before committing to a full pack — useful when the difference between a 420158 and a 420169 nozzle decides the quality of a visible cut edge.
Frequently Asked Questions
Q: Which machine does this fit?
The consumables are for the Powermax125 platform and its 45 to 65 amp configurations. Match the part number on the worn component to the number in the variant list before ordering, since nozzle and shield geometry differs between amperage ranges.
Q: How do I know when to replace a nozzle?
A widening kerf, an angled cut edge, extra dross on the underside or a noticeable drop in cut speed all indicate nozzle wear. Electrodes should be replaced when the hafnium insert is cratered to roughly 1 mm depth.
Q: What is the difference between the standard and ohmic retaining cap?
The 220977 standard cap is used for hand and general cutting. The 420156 ohmic cap carries electrical contact for torch height sensing, which is what a mechanised table uses to maintain a consistent standoff.
Q: Which parts are for gouging rather than cutting?
Nozzle 420001 is the gouging nozzle. Shield 420112 gives maximum metal removal for aggressive gouging, and 420519 is the shielding choice for maximum control where the gouge profile needs to stay shallow and even.
Q: Should I buy single pieces or the larger packs?
Single and 2 piece options suit testing and setup. For regular cutting, 5 and 10 piece packs are the practical size. Shops running hours of plate work should take the 20 piece packs, which is where the per-piece cost drops.
Q: Are these genuine consumables?
They are KEMAO parts carrying CE certification, supplied for the Powermax125 platform. As with all plasma consumables, part number matching to the machine and the amperage range is what determines performance.
