#5 Older non-squarewave HF tig units. Do your AC HF welds wander? Electronics interferance, ect.
Solution:1) Tyewrap the positive and work cables together within the first 3 feet after leaving the HF unit or welder.
2)All option or portable HF units must be plugged into the welder being used, not to an extension cord!
3) **Note for all HF users**Always isolate the primary ground an HF welder either into the actual earth, or back to the incomming Bus bar, Do not attach it to the conduit, or breaker box!
