Hi all, I went out today to look at buying a used arc welder and came home with a 140A CIG Transarc Easywelder and also an Oxy-Acet kit, which was a D size bottle of each gas, plus a Comet 3 welding torch plus the 2 CIG gas regulators.
All for the price of $30 ($20 for the arc welder and $10 for the rest)
The Oxy bottle is almost empty (100kPa left) but the Acetylene has 1000kPa in it which I think is about half full, still I thought that this buy was a steal at that price!
The only reason I got this welder is that I am in the process of making a spot welder out of a microwave oven transformer (MOT) and thought that a larger power supply might be better, and as we all know size does matter! right
.
I have rewired the MOT, by removing the high voltage secondary coil and replacing it with 70mm2 welding cable which should give me about 800A+ at 3.05V but figured that the transformer out of the 140A welder should give me about 1300A+ once I replace the secondary coil wire with some thicker cable, and it is probably better suited and able to take larger currents loaded on the primary coil plus a better duty cycle. So I will see how it goes once I pull the welder apart and rewind the transformer
.
Cheers
Ed.

) but at least I don't think that there is anything wrong with the welder itself. If I was to keep it as a welder I would replace the leads as the cables are really too thin in my opinion.
