OK thanks for the feed back guys, just for some closure to this thread.

I bought the mini-ductor MD-700 I think. worked nice on quasi stuck CV shaft bolts. Tested on a bolt, it did heat the bolt/nut up to cherry red about a minute.

Saw that RMCybernetics and the fluxeon free ones. But didn't have time or the equipment to make one at that time of posting, it was about to get cold to work outside laying on the ground, Sept/ late Oct I think by the time I got all the car parts and needed to get things replace and fast. Maybe one of these days will make one between.

Was hoping maybe miller makes one as an accessory. These welding power sources should have enough power to even do a 2kw metal melting furnace. But being a welding company probably this is not their focus.
