Hello everyone, I've been lurking here for awhile and have finally decided to post. You guys have some great information on here so good work and thanks. Now as to the question my job has some ****ty welders I mean bad these idiots have broke nearly every machine where it can not be adjusted by anyone other than matinence. Apparently welders never have to adjust for different thickness or types of welds. Anyways that leads me here as I'm having to try and do. My own machine I'm using an old Hobart this picture has all the relevant information you will need to know about the machine. The problem is that for some reason the output contrator control button has stopped working it will barely arc and a puddle is out of the question. It does nothing but pop and burn through. However if I turn the contractor off it welds fine except it arcs even if the trigger is not depressed. I have scoured google and can find nothing about this. The only thing I can think has happened is that it's bypassing all the switches. And staying hot ? If you have any information that could help me as to what's causing it and a remedy id appreciate it. Also here's the kind of welds I have to deal with fixing daily because they are "good enough to go" enjoy.
