Ever used a 400A welder running at full tit ?
If not you are in for an experience.......300A is as hard as I've used and that ate 6g rods for breakfast !  :o

Well when it comes to full tit, I have no experience with Arc welders, so wouldn't know. Now up here there is a difference between tit, and tilt, so that could make an upside down world of difference!

Hmm, my 400A AC 2 phase stick welder cost me just $200.

Duty cycle at full tit is another consideration fan cooled or not.

You can always parallel two welding machines, AC or DC. I have a couple of Millers that I've done that with a few times when using jet rods.

It's a lot easier on the machines when they are sharing the load.

Yes! Both jet rods and arc gouging!  :(

Most people would never believe the heat generated by either of these at those current levels. A white pipe-liner hood is noticeably cooler than a grey or black one.
