I got an odd issue happing at a shop that I basically re-wired. Installed 200amp load center down from a new metered main panel.The guys who own the shop call and tell me the tig welder (A big *** Lincoln stationary 100amp 240volt, switch in AC position) when in use makes the mig strike an arc (wire is touching the work table) (Nobody is touching the migs handle)Im stumped on this one. All my grounds are good (correct size and all on same buss bar)Im thinking the ground clamp on tig might be the problem or maybe the tig itself be the issue.The shop had some serious electrical load balancing issues with an under sized load center. That needed a fan blowing on it so the breakers wouldn’t trip as fast. Might’ve damaged the welder?Has anyone had this or a similar problem before?Oh the work table has a 2” flat stock running across the floor from tig grounding electrode and it’s welded to leg of table.Last edited by Electric; 23 Hours Ago at 11:00 PM.
Reply:Just another example of why calling the work clamp a ground clamp makes things confusing.Check out my bench vise website: http://mivise.comMiller Syncrowave 250DXMillermatic 350P with XR AlumaProMiller Regency 200 with 22A feeder and Spoolmatic 3Hobart Champion EliteEverlast PowerTig 210EXT
Reply:So if tig is welded with the mig torch starts welding by itself ? Actual high amperage welding arc. Or are we talking about a tiny little arc that does melt anything ? Is the work clamp of the mig also clamped to the table when this occurs.Is high Frequency on when it occurs ? If you weld with out high freq does it still happen ?
