Having infinitely adjustable control is nice but I have had bad experiences with welding machines that have sliding cores in the transformer. The stepped control is bullet proof. The only problems after twenty plus years with my AC Lincoln was that the contacts corroded over a bit and I had to wiggle the switch when I moved it to another setting. This understandable since it would only be used a couple of times a year. Not having the exact amperage setting that you think you need is not a big deal with stick. You quickly learn to adapt. Randy
found 2 similarly priced machines
hobart 225/160 and lincoln 225/125
hobart has infinite amp adjustment with a crank style adjuster , and the lincoln is a tapped style amp adjust .
pros and cons please.
thank you
