Hobart tigwave 250, wont arc

admin

Got my machine all wired up tonight, went to strike an arc, nothing. I tryed ac then dc + and -. Pre flow starts like is supposed to, and postflow also works. I tried the machine on high freq start and continuous. Had it set to around 80 amps. I used a multimeter and checked for continunity between the tungsten and the lug on the machine, A OK there. I even tried touching off on the work piece, nothing. Any ideas on what to check next?
Reply:Start with the obvious since you just wired it up. Are you sure you have 230v at the machine and have you physically verified it with a meter? You wouldn't believe how many "broken" machines are simply miswired. In some cases some functions may still work even if the machine isn't getting 230v power, but only 110v from one leg..No government ever voluntarily reduces itself in size.

Reply:Multimeter came up with 226v. It was originally set to run 480. I moved the bars in the machine according to the manual for 230v
Reply:Ok, bringing this back up to the top. Took out the points, resurfaced them, and tried multiple gaps. I can only get the machine to do one thing, shown in the video. This is on ac high freq continuous. Any other setting the machine will not do a thing. Even in stick,mode, you can touch the tungsten directly to the ground clamp with NO arc. Ive tried everything within my capabilities, Im going to try calling a LWS who has worked on these hobarts.Click the pics to play the video, if it matters ive tried up to 150 amps, 3/32 ceriatedThis can be moved to the hobart forum if that is more appropriateLast edited by neverfastenough; 12-02-2012 at 07:12 PM.
