lack of input power ,,, you simply need a bigger supply , something will not like what you are doing to it ,,, and it will get very expensive.Thanks for the info.
I'm finding it quite sporadic whereby it trips intermittently when I pull the trigger before even getting it to arc. What would cause this?
I think if it’s tripping the rcd then it’s not specifically tripping because it’s too big (though that may be factor) - an rcd is a protection device that monitors current and trips if it detects any current flowing to earth (that’s a very simplistic explanation) - so a bigger breaker may not be the answer?
No idea, to my mind if it’s the rcd tripping then a bigger breaker might not help but maybe it wouldI did wonder if mine were doing this.
They were all older machines and I had no problems running newer inverter machines on higher output settings. They did all work fine on a bigger socket though and I would think the fault detection on that supply would be just as sensitive even if the breaker was rated higher?
what is tripping the 30 ma rcd on one or both or is it the mcb-sThanks for the info.

It is connected to a 16A supply in my garage which fed from a 40A supply in my house.
it was only tested 11 days ago. a full; insulation test on the fixed wiring in the house db and garage db is required as the welders been tested but nothing else hasIf it's one of the RCD's tripping (the unit with the Test button, either the house one or the garage one), then it's not a supply issue it's an earth leakage problem. In simple terms the RCD is detecting that all the current running out down the live wire is not returning back on the neutral wire, i.e. some current is leaking elsewhere, to earth somewhere. Although your welder has a fresh test cert I would be a bit suspicious, has anything got wet recently? Could also be metal / grinding dust inside causing tracking to earth, whip the covers off and have a look (unplug first of course!)
