I’m a little bit confused cause my Hobart Handler 190 can’t weld 1/4-inch steel, Using 0.035-inch wire at 22V, and welds don’t penetrate. any settings to fix this?

[Lauren Wilson]

Thick steel needs higher voltage, Set Handler 190 to 24V, Use 7018 electrode for better penetration, My Hobart struggled too, Clean steel with acetone, set wire speed to 250 ipm, and use 25 CFH argon.

Try 0.045-inch wire, it is better for thick steel.

[Jeffrey Adams]

poor penetration means low amps, Increase to 180 amps, My Hobart welds thick steel now.

[Douglas Graham]

Bevel edges for better welds, it helps with penetration.

[Robert Austin]

Check the ground clamp, loose ones reduces penetration.
