was a little tricky to fit but my welder was running good as new again an hour or so later
fitting this part required a little bit of tech knowhow but then if you're using one of these already then it shouldn't be an issue.. it does require popping the lid off the welder and fiddling with the internal wiring but all doable and took me less than an hour to get the old girl up and running again. just take photos of how it was before you start undoing things and you'll be fine :)
