I have a power TIG 200 DV. The only problem I had was erratic arc on AC..

It was easy to adjust the sparkgap two locking nuts and two screws... it was at .038, adjusted it to 30..
it seemed to fix the problem... still not great at low amps.. but better

My understanding is that the digital machines have a solid-state sparkgap that needs no maintenance My machine a Everlast Power TIG 200 has points, easy to adjust with a screwdriver, seven screws the back comes off, 10 screws the cover comes off leave the front cover alone. Welding on DC no problem....

vary confusing, the tech folks at Everlast just had me decrease the sparkgap to make my arc more reliable

does anyone have a clue what the spark gap does.... Just adjusted it on my Everlast power TIG 200..
it was .038 and adjusted it to .030.. Made the arc steady on the min setting of 20 amps.. At the original setting the arc was cutting out, sounded like I was losing the ground clamp connection.

clean the copper with vinegar and salt first then try using 14ga copper wire for your filler metal...

just trying stuff... Tried silicon bronze on DC and it worked ok... Talked to the welding supply guy about aluminum bronze and would it flow better and he thought it would.. Because of the aluminum, though I should us AC... Then got off trying aluminum bronze on AC.. Now why is the arc not steady, (...

New to Forums and welding.. My goal is to weld and braze auto body panels With that said last year I got a Everlast Power TIG 200.. With the help of Jody's videos I got to the point that I can weld in DC mode on sheet metal. Did a little aluminum and it seems to be okay nothing great.. Now I'm tryin...
