Evening ladiemen and gentlewomen,
Got one of the above Arc Welders.
Massive transformer inside with a sliding shunt.
Got given it, so no real skin off my nose if I can't get it working 100%, but it's be nice. Also picked up a box of 1.6mm, 2.5mm and 3.2mm rods from my uncle, who got them from Stores on his last day *cough*, damp, but they dry out alright. Reminds me, need to build a rod warmer.
Anyway, back on topic. It'll weld alright, laid down some very wobbly slag lines a few weeks ago when I'd run out of gas, and encountered the following, potential, problem.
If I switch off the set on the front of the machine, no rod in the holder, earth clamp free and well away from anything that could conduct, it will every now and then trip the power out. I do actually suspect that it has something to do with the length of cable running from the CU in the house, down to my workshop/garage/**** tip. It the house end RCD that trips if I remember correctly, but I packed the machine up after finishing and haven't needed it since to be honest.
Now, there aren't a lot of things that could go wrong in one of these, they're litterally and big transformer. I had however, thought of putting a 240v fan in the back of it to pull some air through the unit, just to increase duty cycle a little if possible.
Other than that, could anything be causing this?
