I got the gas coming out now, but it's leaking somewhere near where the gun connects to the machine at the power block. Checked the gun o-rings, they appear OK, but I'm going to replace them anyway. I *assume* that the usual hardware/auto parts store o-rings will work OK? they don't need to be the orange Lincoln type?I probably have a couple laying around if interested.
And that's exactly what I found when I replaced the o-rings. I was seating the gun cable against the cable cover, not the brass cable seat. Pulled the cable end out a half inch or so and the the cable did seat properly into the power block. Easy to see when you know what to look for.Check it with leak test. The gun has to be in perfectly too. I know you checked that but maybe the wire outlet guide is pushed too far toward the gun keeping it from seating.
