The Klutch MIG/Stick 220Si 230V Multi-Process Welder with Spoolgun is unmatched in capabilities and value. The inverter-based system offers increased power output from a smaller transformer, resulting in a super lightweight system that weighs up to 50 less than comparably powered traditional models. The lightweight and powerful inverter design makes this welder extremely versatile. From MIG to Flux Core to DC Stick, and even DC TIG welding capabilities, this one package can handle it all. Whether you're welding aluminum, steel or stainless steel, the Hybrid MIG/Stick 220SI shines through with performance you can count on. Optional 10ft. TIG Torch is available Item# 44455, sold separately. Professional Features: Increased power in a super lightweight package for exceptional portability The inverter system better handles fluctuations in input power for consistent output and better welds Requires less input amperage, reducing the overall input power requirement by up to 25 when compared to traditional transformer welders Infinite voltage control gives you total control of your welding arc to get the results you want. Use this feature to dial out spatter or control the weld puddle while welding overhead Dual-purpose overload protection helps keep your equipment safe - protecting your machine from incoming power voltage spikes. It also turns off weld output when the machine is at too high of an operating temperature Quickly and easily switch from MIG welding to Stick welding and back again. Have both processes connected at once and simply switch processes by flipping the process selector switch Easily switch from MIG welding steel to MIG welding aluminum by removing the MIG gun and sliding in the spoolgun. Then simply switch gas bottles and you are ready to weld The welding setup guide provides you a quick reference starting point to help you get welding quickly
