HITBOX 110V 3IN1 Portable MIG Welder ARC LIFT TIG MIG Gasless Welding Machine. Full-digital control system to realize precise control and stable arc length during welding. Great reduction in metal loss obviously enhances the welding efficiency and energy-saving effect. Closed loop feedback control, constant voltage output, workable under network voltage fluctuation within ± 15%. The inverter frequency is 35 kHz, greatly reducing the volume and weight of the welder. Unique dynamic characteristic control circuit is used in gas shielded arc welding, stable arc, little spash, good ahping, efficient welding. Switching frequency is beyond the audio range, which almost eliminates noise pollution. Perfect For Home, Auto Repair Shop & Other Welding Shop. Please note: when using the mig function, please connect the earth clamp to the positive pole”+”. Inverter MIG welder 110V, the machine carries MIG/ARC function in one. MIG(Synergic)mode: no gas iron welding, using 0.8mm flux cored wire to weld 0.8-3.0mm thickness metal, duty cycle:50%. ARC mode: using 1.0-2.5mm rods to weld 1.0-5.0mm metal. MIG/ARC Weldable metal: Iron, stainless steel, galvanized sheet, carbon steel(Cannot weld aluminum). MIG welding: 0.56mm iron and mild steel plate. Lift TIG welding: 14mm stainless steel plate. ARC welding: 2.5mm acid electrode like J422 E4303 6013. Feeding speed adjustment range(m/min): 1.5-16. Welding wire diameter(mm): 0.8/1.0. Packing weight: 5KG (15.70LB). 1x Flux Core Wire. The TIG torch is not included. A 110V to 220V conversion cable is not included. You need to order extra, otherwise, it can’t work under 220V.
