YESWELDER 200Amp Aluminum MIG Welder YWM-200, 110/220V Dual Voltages MIG Flux Cord Stick Lift TIG Multi Proces MIG Welding Machine, Spool Gun Compatible Aluminum MIG Welding Capable of welding aluminum by using 100% Argon. Graphene feeding liner with regular MIG torch with Synergic MIG control 2. Spool gun with Manual MIG control. Recommend aluminum welding wire(1lb): Silicon Aluminum ER4043 and Magnesium Aluminum ER5356 Welding Wire Optional Functions Voltage Reduction Device:ensure the operator's safety while in idle mode Anti-sticking:lower the machine's working intensity and allow the stick welding electrode to be easily detached Arc force: assists in stabilizing the arc, preventing the arc from cutting out while welding, and preventing electrode sticking. Hot start:increases the ease of starting electrodes, especially under challenging conditions such as damp electrodes, imperfect job surface, or when using'difficult to run' electrodes.
