I could not pass up the machine it came from the shop of E.A. Chase, Chase is closing shop and had a sale of the tool that he no longer needs. I had to get approval through "Head Quarters" (my girl friend) and I am replacing my old Idealarc 250 stick welder with this monster 300 , 375 amps @ 60% duty cycle. Now I need more power to the shop, sparky is going to come check out my panel to see if I can get another 30 amps out of there. I got the welder home yesterday and removed the sheet metal to find that a mouse had taken up residence in side and after much blowing with air found the culprit all crispy, the way I like em, well done. I got every thing hooked up and working, tried out the high frequency unit, did a little stainless weld test. this thing has great arc characteristic real smooth.
