Powermax 45 XP Consumables FAQs

Consumable sets for a 45 amp air plasma system: cutting, fine cutting, gouging and marking.

What different consumable sets exist for one plasma system?

A single plasma system often has several consumable sets, each built for a job. The main ones are standard drag cutting (hand torch), mechanised cutting (machine torch), fine cutting for thin sheet, gouging at higher or lower current, and marking at low current.

Sets differ mainly in the nozzle and shield, and sometimes the retaining cap and swirl ring. Choose by the job and the torch type, then confirm the exact parts against the system's parts list or manual rather than guessing from the look of the old part.

What matters when using fine-cut consumables on a machine torch?

On a CNC table, the machine largely decides cut quality. You need a rigid torch mount, reliable torch height control and enough cutting speed for smooth, square edges. Slow speed on thin sheet tends to give dross and a wider cut.

A shield is generally preferred to a deflector for better cut consistency and nozzle life. Wipe spatter off the front of the torch, because it affects cut quality, and always follow the system's cut chart for settings.

What is an ohmic retaining cap and do I need one?

An ohmic cap or shield has a contact that lets a machine's height control sense the plate by electrical contact, so the torch finds the surface and sets a correct pierce height automatically. It is only used with mechanised cutting where the table supports that function.

A hand torch normally does not need it. Fitting the wrong cap can leave the height sensing unreliable or not working, so match the cap to your torch and your cutting table's controls, and confirm against the manual.

What is the difference between controlled gouging and heavy-removal gouging consumables?

Both are gouging consumable styles. A heavy-removal (aggressive) style is meant for rapid metal removal, deep gouge profiles and heavy washing of metal. A controlled (precise) style is meant for more careful removal, with a shallower profile and light washing.

If you are new to gouging, or removing a weld or small defects, the controlled style is the usual starting point. Choose the heavy-removal style for heavy removal such as cutting out thick welds. Always check the style is intended for your torch and current range, and follow the maker's manual.
