Hey everyone, I'm a mech engineer that's got an electrical question. I have a vintage 1994 Century 230A AC/DC stick welder and just picked up a Century 115-007 HF box and tig torch. Before running this setup, I wanted to confirm whether I need to add a filter to the welder output leads? I've seen this referenced in some posts, but it's not clear if all setups require. The HF box is a spark gap design and the welder is a moving shunt transformer. Neither of the manuals for the units state requiring a filter. That made me wonder if a filter was already in place. I pulled the cover off both units and we was looking for a bathtub style cap, but did not see one. I did pick up some 0.05uF 1kV caps to put on each lead (5 leads total on this welder).Just looking for some input to make sure I'm doing the right thing to protect my equipment. Thank you!
Reply:Since it is a HF box, I would call Harbor Freight, and see if they could help me,,As far as filters, I stay away from FRAM,, and I prefer WIX,,,As far as electricity,, I probably know less than the OP,,I hope someone comes along with the RIGHT answers,,,
Reply:Never heard of a "Filter" (this is a cap?) but to reduce spurious "noise" there might be a, specific, Ground connection on the back (maybe not in '94 but, most modern welder with HF have this) that you run to a stand-alone ground rod, not the Equipment Ground...
