Any comments on the reliability / servicability of the Lincoln Square Wave TIG 255?
In particular has anyone had trouble with the digital controls?
This now discontinued welder has DC, AC Square Wave with HF, Pulser from 0.5 to 10Hz, Auto and Manual Balance adjustments (wonder how the autobalance works?). Lincoln also offers a 2 step and 4 step "sequencer" which ramps up current using an "arc start switch". There is also a gas afterflow adjustment.
Thanks, Graham
