I got a second hand Nelson Arc Lite Plus Stud Welder recently from an auction. I'm keen to use it but I'm not experienced with this type of welder and having a problem. Unfortunately I can't find much about this type of Nelson welder. It's not on the Nelson website, however it seems that Arcon make a similar welder, called the 'Studhorse 1200 DM'.
Basically the studs aren't actually welding to the work piece. I've attached a video for you to see for yourself. According to the manual's suggested settings, I have it set for M8 Studs, 550A and 0.25 Seconds. When the trigger is pressed there is a short 'squeal' and but the arc is not happening. I've messed with the settings and turned it up, at 1000A it still doesn't work however it did arc a few times at 1000A and burn up the stud.
I'm guessing it's a problem with the lift mechanism inside the gun. I looked inside the gun and all seems well. I'm worried it's something with the welder unit itself. I'm considering getting the gun reconditioned but basically I just wonder if any of you guys have experience with these types of welders or gun.
Thanks lads and lassies
Sorry for the poor quality of the video.
