AUTOOL M508 ARC MMA Welding Machine DC Inverter 20-160Amp IGBT Stick Welder 110V. AUTOOL M508 is a advanced arc inverter welder. The welder was controled by intelligent circuit board with IGBT, arcing immediately, low splash and smooth in weld joint. Mini body allow us to take it to anywhere, low power-consumption and high efficiency in heat dissipation let us work with it all day long perfectly. AUTOOL M508 arc welder controled by IGBT(Insulated Gate Bipolar Transistor), master current more exactly, low splash and smooth in weld joint, help us make a perfect welding. Digital chip control, arcing immediately. Built-in ultra low voltage intelligent regulator, started in unstable voltage area easily. Shell manufactured by cold-rolled steel, integral moulding with amazing structural strength and durability. Full metal body and blind shutter on shell is convenient to heat dissipation, 4KG weight and ergonomic handle allow us to take it to anywhere, perfect for wild and aloft working. Automatic power-off protection for overheating. Thickening version aluminium alloy radiator designed in serrated, radiating in sectional type. 4100 turn/min mute fan for fast heat dissipation. Pure copper core cable, current output stablely, loss little power even if transmit it in long distance.
