Thanks for the update!

Is it a rheostat or a potentiometer? How did you check it?

What is the serial number and stock number of the machine?

My Millermatic had a 30% duty cycle at 140A. I exceeded it once on a large weldment already fitted up. I should have taken a couple more breaks while stitching it together.

If you do lots of those, the duty cycle will matter. But I'm still skeptical of Snap-On quality and parts availability....

I was thinking similarly, except I would buy two Hobarts and put them on separate carts. Still come out cheaper than a Snap-On, and have a machine on each end of the project. Less moving of the carts, and they weigh a lot less when you do.

And I also had the same thought: how can this...

I agree they have a much higher duty cycle than typical 120V machines, and at 3x the weight, but is this the one? I only see a 60% duty cycle at max 140 A. I definitely agree that is significant, however.

"Welds 1/4"...

Unless otherwise stated, it tells you a "Rated Output." This is the output they use to give the "rated duty cycle" used for comparisons between machines and advertising purposes.

The stock number under the serial number in the photo is for a CC-only version of the XMT 304.
