The FlushCut™ process for Powermax 125 systems provides users with the ability to cut closer to base materials than ever before.

Reduce time-consuming and costly grinding.

Close cutting for removing lugs and other attachments has typically been performed via oxyfuel cutting or carbon arc gouging, followed by labour-intensive grinding. FlushCut for Powermax plasma systems provides a new, more efficient process for challenging removal applications.

The patented consumable design for FlushCut features an angled nozzle bore design which delivers the plasma arc at a 45° angle – essentially bending the plasma arc. This unique design gives Powermax users the ability to cut closer or more flush to the base than ever before which significantly reduces grinding and increases the opportunity to reuse pad eyes, attachments and other temporary weld supports.

Hypertherm FlushCut Consumables - Introduction

Powermax 125 / Duramax Hyamp Parts FAQs

Practical answers on the consumable parts for a high-current air plasma torch: gouging, fine-cut and drag-cut sets, wear checks and fitting.

How are gouging consumables different from cutting consumables?

Gouging is a variation of cutting in which the arc is deliberately defocused, mainly by changing the nozzle orifice size, so the torch removes metal in a wide, shallow groove instead of cutting through. Gouging therefore uses its own nozzle and shield, designed for that job, rather than the parts you fit for cutting.

Fit the set that matches the gouge you want, and check whether your machine has a gouging mode that adjusts the gas pressure before you start. Your manual's consumable chart shows which nozzle and shield belong in each mode.

How do I tell when an electrode is worn out?

Normal wear shows as a small round pit forming in the centre of the electrode tip, which slowly deepens with use. When the pit becomes too deep the arc can attach to the copper holder instead of the emitting insert and damage it, so replace the electrode before it reaches the point where it will no longer start or hold the arc.

The pit depth at which to replace depends on the maker and the current, so use the figure in your manual rather than guessing. A pit that is ragged, off-centre or very black can also point to a problem with the gas, so check your air.

What does a worn nozzle look like?

A new nozzle has a sharp, round orifice. Replace the nozzle if the orifice is nicked or notched, has gone oval or out of round, or has rounded-off edges. Slight enlargement of the hole is normal wear, but it shows up in the cut as more bevel, more dross on the underside and a wider kerf.

Most makers advise changing the electrode and nozzle together, because a worn electrode quickly damages a new nozzle. Never refit a nozzle you have already judged to be worn, and keep it clear of slag.

What are fine-cut consumables for?

Fine-cut sets are made for intricate, fine-featured shapes in thin sheet. They are designed to give squarer edges, tighter tolerances and a narrower kerf than standard parts, and they are normally used at the lower end of the machine's current range on mild and stainless steel.

They are made for both hand and machine torches. On a machine table the result also depends on a rigid torch mount, good height control and a suitable cut speed. Maker guidance recommends a shield rather than a deflector for consistency and nozzle life, and expects small adjustments from one sheet to the next.
