Hobart handler 135. Not sure if they with it or not out of convenience, but it has a miller gun. Kinda wondering if it's stock or was changed out later for something similar. If I'd torn into it earlier I could have swung by the place that sells these and got some trigger parts, or even looked at a better pic, but I didn't do it early enough. Not it'll have to wait till atleast wednesday. My friend has a miller thunderbolt (or something similar) arc welder that just needs the end of the lead or something, I might see if he'll let me borrow it if I split the parts cost with him. I know I saw the ground and work lead ends at home depot.
