I know the input voltage is 240, I need to verify the sine wave on the Hz end on my welder/generator, plus do a check while under load.

The SC50 that arrived had the regulator in front as well, it's just the better quality (?) water separator/regulator that came with it vs the simple water separator on the PP50.

Cutting height with the last attempt with the roller guide was 1/16" (shimmed the tip, then set the rollers). Static inlet pressure is 87ish psi (finicky regulator).

The roller guide that came with the S45 (inside the box) barely went half way up the cup. The one that I bought from Everlast separately goes all the way to the collar. It's a decent fit, but still has some wobble to it even with the set screws tightened.

As for the cut capacity, it may very well be my current power source (another thread going on that) and lack of proper tip size. I get that these are designed for shop use/hobbyist.

Being a field service tech, my shop is my truck, I have no ceiling, my floor keeps catching of fire (grass), and my workbench is whatever is available, typically my bumper (8' x 20") and vise. One does what one can with what is available. It's small, portable, and does what I need it to - the majority of my fabrication is 1/2" or less. If I have really thick stuff to do, I grab the oxy/acel kit. Cuts much faster. I just needed to find out just how far it can go with what I have. As it is, not many field service techs tote around a MIG, let alone a Plasma cutter, drill press, and shop saw. I have to look at the type and amount of work to be done, and calculate the setup time to see if it's worth dragging out the non-typical field tools.

Really thin welding, confined area, or a lot of tack welds - MIG

Drill more than 6 holes or they have to be precision - Drill press

Heavy quantity fabrication, or a lot of welds to remove - Plasma

Precision cuts on box, strap, or pipe + more than 4 - Chop saw.

*note - precision denotes within 1/16" or 5* angle
