Like I didn't already ask enough questions in my plasma post, here goes two more. I'm curious if anyone has any advice on two separate problems.
I have a Lincoln AC (buzz box/tombstone) stick welder. I've owned it about five years. It is not used commercially so use is light. Not too long after I got it became progressively harder to turn the current selector dial. I never turn it when the unit is on. It got so bad that the other day I had to turn it so hard that the dial's fork actually popped out of the slot due to the pressure. The unit is inside and doesn't appear corroded inside. Everything looks fine inside the case.
The second issue is with a little Chicago Electric 110 Mig welder. The wire feed has been horrible since day one but I chalk that up to "you get what you pay for". When it feeds right it has always done a decent job. the other day it stopped making any spark. The power comes on and the fan turns but there is no spark. Even when I touch the welding wire to the ground clamp, nothing. Can anyone tell me what I might check? I couldn't find a fuse but I can't swear that there isn't one somewhere.
