My multi-process welder with plasma cutter is arc is weak at 45A, 70 PSI on 3/8-inch steel, cuts is shallow. Any solutions?

Weak arc is from low air pressure. Bump to 75 PSI, my combo cuts better.

Replace torch electrode if worn, clean tip with alcohol to boost arc.

Check air hose for leaks.

Weak arc is from worn electrode. Replace torch tip, use 75 PSI, my combo struggled too. Check air hose for leaks, try slower travel speed, use 50A for deeper cuts to improve penetration.
