Hello, I'm new to the forum and haven't posted before but thought I'd give this a go and see if any one can help. Ive got a SIP 184 (the combo Tig/arc/plasma unit) and has seen relatively little use but when I went to use on TIG, it shuts down, hear a click and pretty sure fan cuts out as well (been a wee while since I used it but it used to be OK with the same set up). Releasing the trigger, it goes back to normal, fan restarts and display comes back on. Weird thing is if I disconnect the earth (or return) lead from the bench, and have a "floating" earth on the workpiece, it welds fine and behaves normally. Any ideas? The problem is in the welder (I'm pretty sure anyway) as I also have an R-Tech200 AC/DC and it works fine on the same bench.
Thanks in advance
