1.Designed for heavy duty stick welding needs. No matter cellulosic, low hydrogen, stainless steel or hardfacing electrodes,it can produces a smooth, quality arc for consistent results day-in and day-out.
2.Substantial amperage ranges at 20-500 amps.
3.Easy to operate - Microprocessor panel control makes procedure setting simple and easy.
4.Smooth arc - Easily weld with mild steel, low hydrogen, stainless steel and hardfacing electrodes.
