I am completely new to GTAW and need some help/advice. I have a white faced older DIALARC 250 AC/DC and a HF-251D-1. I have read from previous posts that this is not an optimal setup because there is no contactor on the older DIALARC machine. In the HF manual it mentions that the HF unit can be "field equipped" with output control (contactor) for use with welding units without a contactor, does anyone know if Miller still offers this output control for older HF models ? The DIALARC is from the early 70's and the HF I think from the late 80's. The TIG torch has a hand control for gas flow and High Frequency but I would love to get a foot pedal current control device for the TIG. Any help is greatly appreciated !
