Most wrong Powermax® orders come from the same place. Somebody reads the number off the front of the machine, searches that number, and buys a stack.
But Powermax consumables aren't grouped by machine. They're grouped by torch. And four different torch families have hung off machines wearing the Powermax badge.
Get the family right and the rest is easy. Get it wrong and you've bought parts that physically will not go on your torch.
The four families
Duramax® — Powermax 45 XP, 65, 85, 105. The big one. If you bought a Powermax in the last decade and it isn't a 125, this is almost certainly you. One torch set covers four machines, which is why these parts move more than everything else combined.
Duramax HyAmp — Powermax 125. Different torch, different parts. The 125 shares a badge with the 65/85/105 and shares almost nothing else. This is the single most common mix-up in the range.
T45v / T45m — the original Powermax 45. The plain 45, not the 45 XP. If your machine predates the XP, check the torch before you assume it takes Duramax parts.
Duramax G3 retrofit — Powermax 1000, 1250, 1650. The older T60, T80 and T100 torches these machines shipped with have been phased out. The G3 retrofit torch is now the path forward for those systems, and it changes which consumables you're buying.
How to tell which one you've got
Don't look at the machine. Look at the torch.
The torch model is printed on the torch handle or on the machine's data plate. That string — Duramax, Duramax HyAmp, T45v, T45m, G3 — is the thing that determines your parts. The amperage on the front of the box tells you which stack within that family; the torch tells you which family.
If the label's worn off, count what comes out of the torch when you strip it and compare the shield diameter against a known part. Or send us a photo — we do this all day.
Hand torch or machine torch
Second fork, and it matters as much as the family.
A hand torch and a machine torch in the same family share the nozzle and electrode but take a different shield and a different retaining cap. The machine version uses an ohmic retaining cap because mechanized cutting needs height sensing; the hand version doesn't have that job to do.
They look similar in a drawer. They are not interchangeable, and a machine shield on a hand torch is one of the more expensive ways to learn that.
The 105-amp trap
Worth naming specifically, because it catches people who otherwise know what they're doing.
The retaining cap that covers 45, 65 and 85 amps in the Duramax family is not the cap you want at 105 amps. At 105 the correct part is T-11422; the 45/65/85 cap is T-11423. They share a family, they look closely related, and one of them is wrong for your machine.
That's why our finder checks the amperage range on every part in every stack, not just the OEM cross-reference. Matching numbers is not the same as matching fit.
Pack sizes
Some Powermax consumables come as five-packs, not singles. Electrodes especially. That's normal — it's how the manufacturer supplies them — but it means a nozzle at one price and an electrode at another aren't the comparison you think they are unless you check what's in the box.
Our product titles carry the pack quantity, and the finder shows it on the stack row. Read it before you compare prices against anything.
Let the finder do it
All of the above is one screen on our Powermax finder: pick your torch family, pick hand or machine, pick your amperage, and you get the complete stack — shield, retaining cap, nozzle, swirl ring, electrode — listed in the order they go into the torch, with the pack sizes shown and the OEM cross-reference against each one.
It's free. You don't need an account and you don't have to buy anything to use it.
