Nah, live around the block from this customer. Though with the "Inverter" tech they are now building welders with, the unit is no bigger then the outside dia. and twice as thick as your brief case. Yes, in both 120 &240, some have both... And with the correct unit, you have 220 Amps of working power. Which means there is NOTHING one cannot weld in the field. Some of these units are about Half the size of brief case and are tig or stick. add a spoolgun and you can mig in the field. My cost on that heat assy was 62.00 welded it up for 80.00 saved customer 60-70 bucks their happy-happy less then 20min for repair. Win win for every one here, oh, no return trip to parts supply.......Saved that fuel & wear on truck. Google usaweld.com thats one brand, Miller another but their price makes it out of reach just to get one for the truck, and or around the shop.
