Yes the frequency matters but so does the output amperage, and that little welder puts out 135 A max.....to properly weld 3/16 steel you need between 160 - 190 amp output....
and to do 1/4 plate between 180 and 210...
Now in the product description the welder says it will do 1/2 inch plate....hahahah not bloody likely...to do 1/2 inch plate...guess how many amps output you need....cmon who wants to guess....try around 300 to 320....
That little welder barely puts out enoguh amps to weld 1/8 properly...
Now keep in mind that I am talking about single pass welds, but even with a double pass....there is no 110 volt welder that can put out enough amps and volts to properly do 1/4 plate...at least not as far as I have seen yet.
