Are you seeing a spark at the tip when it's trying to start? Older welders had spark gaps in the high freq circuit would fail if debris got in the gap or the gap was not set properly.
There is no debris in the gap and it is set properly. Its set up just like our other robot, but ill look at the tungsten tip while its attempting to arc to see if there's even just a little bit. Normally I can at least see AND hear the arc attempting to establish itself on the part. It will only run once or MAYBE twice before it stops sparking(from what I have observed).. and the same tungsten will work on our other robot after failing to do a second weld on the first robot.
This is an issue that I have yet to find other similar sorts of situations online to compare with, so thanks for the replies!
