Everlast 210EXT review and pictures

Todd, I like how you get right into things. Great pics.

That black "structure" at the base of the unit is kind of interesting... I wonder what it is.

I'm curious to know how the dual pulse AC feature works, and whether that could be an effective substitute for the machine lacking an AC bias adjustment. For example, if you put the machine into "dual pulse" mode, with the background current being the same as the welding current, then varying the pulse duty % could effectively allow you to vary the effective AC bias. e.g, pulse duty at 0% = 50/50 bias pulse duty at 100% = 100/0 bias

Todd, I'd like to see you try some experiments with using the dual pulse feature at various pulse duty %'s with the balance set at the min 20%EP(80%EN), and see how the "cleaning etch width" on aluminum reacts. ...see if you can make the cathodic etch cleaning width completely disappear.

I plan on doing all kinds of aluminum testing in a coupe of days, I have a few jobs to finish before I'll be switching to aluminum. The double pulse does seem like it could have a lot of uses.

Also, "structure" is a good word for the black thing on the bottom, it runs the full length of the welder and is bolted down very secure. There are 2 small brass holes on each side with tiny brass screws recessed, I have not tried turning them, so I dont know if they are an adjustment of some sorts, like an arc gap, or if they are just holding something in place, like maybe the IGBT's like kenwhite mentions.
