Default I think I got these cheaply

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.

I figured that a spot welder would come in handy if I make a box or two out of sheet metal or ally as in the past I have had to either use rivets or use a MIG on the lowest settings.

The Oxy-Acet setup I can use for heating things up or for cutting metal, no real need for it yet as I mainly bought it on a whim as it was cheap at $10. I currently use my 60A plasma cutter for cutting metal but it is good to have a choice, although I will probably use it to heat, melt and harden things with it now that I have it.

Thanks Guys, I think that I will be able to put these to good use, the guy who sold them to me was apparently an very old retired carpenter cleaning out his shed. What surprised me the most was that he had the welder advertised for about 6 months for $50 and no one bought it or even rang up about it till I rang last night, it is in a lot better condition than others that I had looked at that were more money.

So he dropped the price to $20 a little while ago and had listed that price as "negotiable" but really I wouldn't feel right to try and haggle for lower. I tested it out at his place but it was connected via an extension lead and I managed to get a semblance of a bead down, but really my efforts were an embarrassment to me. I figured that it might be an old rod he gave me or the lead, or a combo of the two, or maybe my arc welding skill had gone to crap, but anyway as I was buying it to pull apart it was worth the risk.

After I paid him he asked if I needed an Oxy-Acet setup, so he showed it to me and wanted $10 for it, couldn't get that note out of my wallet fast enough!

When I got home I plugged it in the 15A wall socket and used one of my rods and it worked perfectly. It almost seems a bit of waste to pull it apart now, but my 3 phase TIG 4 in 1 welds brilliantly so Plan A still works for me, I might look around for an Inverter type 240V TIG/MMA welder if I find one cheaply enough.

thirty dollars.
Ed, if I were you I'd think seriously about going to confession.
If you're not Catholic, go anyway.
If you have no attachment to religion whatsoever, I'd still go.

LOL! Oh geez, I am a Catholic and just reading that makes me feel like an accomplice to the crime. Maybe I should go confess it too.
