I guess anything is possible with enough wasted time. Probably best to stick with stick in the sticks.

Just reroute your car's AC compressor to a copper coil to the exhaust manifold, from the compressor to the empty tank, lol. Full by the time you drive to praxair.

should be no steam, condensed out with copper heat exchanger while cooling. I read co2 blends are used for MIG proper, argon for tig, so maybe not TIG for this? I was thinking of dipping hot steel fill rods in borax flux like when brazing, so gas would just be to keep the tig electrode from...

I can't afford (or drive to get) shielding gas. The things I have a surplus of is trees, electricity and empty cylinders. I just bought a combo gas mig/tig chinese job welder. I'd really like to play with shielding gas to weld thinner materials and get away from impregnated flux imperfections...

Trip report: I took the cables apart from the $70 amazon job, and they're all 10 or 12 gauge stranded copper coated aluminum (CCA). Replaced with new tinned copper (core) #4 battery cables. The stinger appears to be cast iron with an electroplating of copper. Just a thin #18 pin loosely holding...

I would argue it's neither AC/DC, AMPS/VOLTS that kill - it's low resistance/impedance by sweat on skin/salt in water combined with a large supply of either AC/DC, Amps or Volts. It doesn't take much to make it to the heart or stop your brain's milivolt message to control your muscle and let go...

wheres the report ? Does it actually crank out 200A or is it more like 160A measured like most of the chinesiamp units claiming 200? I've got a $70CA little igbt unit thats supposed to do 135a but it can barely burn a 1/8 7018, but needs 240v to do the 7018. Still impressive for the price and...

the other dumb idea is using 6000VA 120v-48v transformer out of an old expensive off grid low frequency power inverter, but that would need like 40A of 120v, and it can't be run on 240 or it would be 96v out. maybe i'll just have to suck it up and buy a bigger actual 200A chinese IGBT unit.

Similar case, except no adjustment handle. This unit found on alibaba (pictured) spec's 48v OCV !?: Voltage 220V Power 7.5KVA Voltage 220V Frequency 50HZ Rate input capacity 7.5KVA Output current range 60-200A Duty cycle 10% No-load voltage 48V Usable electrodes...

It's a transformer based 20 year old AC only heavy red actual buzz box. Tried it and it did work on 240, but very aggressive arc. I lost my amp clamp meter to measure actual amps coming out. Didn't try for long, but no strange noises. Curious about the saturation of the TX issue, and how to...
