From the Manufacturer
The Hot Max AC300 is a very heavy duty work horse for when you need to get the job done. The AC300 has fully adjustable current control for as small as 1 amp changes at a time. The AC300 is also fan cooled for longer duty cycles and includes wheels for portability. The AC300 will weld 5/32” rod with ease and works best on 1/8” and thicker metals. The low range output is 35-200 Amps AC and the high range output is 40-300 Amps AC. Don't settle for a lesser machine than only puts out 230 or 250 Amps when you can have 300 Amps for heavier metals or very rusted/oxidized metals. The electrode and ground leads are bolted connections for extra hard usage. Includes 300 Amp AC ARC welder, 300Amp steel ground clamp with 10’ cable, 300 Amp electrode holder with 15’ cable, 5-1/2’ grounded power cable (plug is NOT included), and hand held welding shield with #10 shade. Electrodes are not included.
