I am having a issue
First thing I would check is the relay that sends power to the transformer when you pull the trigger. That can be one of the hardest parts of a Mig welder to troubleshoot because you can read full voltage through the thing with a multimeter when the contacts are dirty and it's not functioning properly.
That's assuming you're losing power. If it's a feed issue then we can address that later.
