| Luckily I've not had a problem with interference from HF on my TIGs or | the current draws. I had an old add-on unit when I moved to the current | location and checked with my neighbours to see if it effected their TV | and other stuff about 6 ' away through 3 4" concrete walls, no issues. | The newer Hitachi HF inverter TIG causes no problems either and if there | is any noise radiated back on the mains lines it has never seemed to | have any effect on the PCs I have running most of the time.
I using a Lincoln 300/300, purchased new back in the 70s. Doesn't seem to both my shop PC either. In fact, the only problem I have ever had was with the Napco alarm system. My current alarm system is a C&K, and it has never complained either.
