The contact tip transfers electrical current to the moving wire. It wears out over time, causing the hole to become oblong. Replace the tip if the wire stumbles or if it exhibits excessive burn-back.
The Century Powermate 70 is a compact, 70-amp, 120V MIG/flux-cored wire feed welder, designed for a variety of light to medium-duty projects. Its portable design makes it a popular choice for hobbyists and professionals alike. It's capable of welding materials ranging from 18-gauge sheet metal up to 3/16-inch steel, making it suitable for automotive repair, home workshops, and farm maintenance. Also known as the "PowerMate 70 amp tote wire-feed welder," it is typically a flux-core-only unit, meaning it doesn't require external shielding gas, which simplifies its use and transport.

Regulates how fast the wire feeds out of the gun. This dial controls your amperage and penetration depth. Faster speeds mean higher current.
Grind material down to bright, bare steel before welding. Check for wind blowing away shielding gas substitute. Wire feed speed is too high or voltage is too low. The Century Powermate 70 is a compact, 70-amp,
