Highest Amperage you've ever used at work

[WelderBoy]

The highest I have ever used has been 400+amps with the air-arc, and about 350 amps welding with 1/4" 7018, and around 350 with 1/16" wire but with the wire you can't say exactly, but I know it is in the 350 range.

But today on our jobsite we were sub-arcing a piece of 1.5" plate with 5/32 solid wire. I asked what they usually set it for and he said close to 1,000AMPS. HOLY HELL! The machine we use at work for this is a Dialarc 1,000. It welds up to 1200amps, and welds 1,000amps at 100% duty cycle.

I was very impressed at the disposition rate of this subarc machine on that plate. It moves 10 times quicker than I do when welding and shoves in about 100 times more wire. The wire was as thick as a pencil. Pretty cool stuff.

So let's hear it, I know there are some crazy welding processes out there, and I know some of you TIG pipeliners weld up to 700 amps on big thick pipe.
