Technical Guides & Fitment Tips

Plasma Electrode Pitting? Replace Worn Electrodes Before You Burn Through Nozzles
If your Powermax 85 electrode pit is deep or off-center, the arc destabilizes and accelerates nozzle wear. Replace electrodes on interval — not after the nozzle fails. Featuring Hypertherm 220842 (SKU 220842).

MIG Gas Diffuser Clogged? Fix Erratic Shielding on Tweco Guns
Erratic arc, one-sided porosity, and random spatter spikes on Tweco-style MIG guns often trace to a clogged or cracked gas diffuser. Fitment-first fix featuring Tweco 52 Gas Diffuser 15201101 (5-pack).

MIG Contact Tip Worn Out? How to Identify Wear and Replace It Right
A worn contact tip causes erratic arc, burnback, and porosity before it fails completely. Know the wear signs, replacement interval, and correct fitment for your wire size and gun.

Gas Hose Leaking? Fix It Before You Waste Another Cylinder
Shielding gas running out too fast or porosity that comes and goes? A cracked or poorly crimped hose is one of the most overlooked leak sources. Featuring Weldmark WM27 Hose Repair Kit (SKU WM27 - 1 KIT).
Gas Cylinder Empty or Low? Run This 4-Step Diagnostic Before Ordering
A cylinder that reads empty is not always empty. Stuck gauges, failed regulator seals, and slow leaks all mimic a depleted cylinder. Four-step field diagnostic before you call for a refill.

Welding Jacket Burning Through? Upgrade to FR Cotton Before You Get Hurt
If spatter is burning through your jacket, the fabric is either not FR-rated or worn out. Upgrade to Black Stallion JF1625-NG stretch-back FR cotton (SKU JF1625-L) for daily protection that stays comfortable.
