Powerful 6-in-1 Welding Machine: This multi-process 110V/220V dual-voltage MIG welder boasts six functions: Gas MIG, Gasless Flux Core MIG, Spool Gun MIG, Lift TIG, Stick, and Spot Welding (TIG gun and spool gun not included). With a maximum output of 200 Amps, it can weld up to a 3/8" plate, so it is suitable for various kinds of welding tasks. For MIG welding, it supports wire of .023", .030" and .035" in solid or flux - cored type and .035" and .045" in aluminum type.Easy Operation: Programmed with a synergic system, the welding machine automatically adjusts voltage and feed speed based on amperage, making it an ideal choice for beginners and DIYers. The control panel has intuitive buttons and knobs for easy adjustments.Advanced Features: This machine also has special functions such as burn - back adjustment and inductance adjustment in MIG mode, and hot start, arc force, and VRD in MMA mode, providing more efficient and customized welding. IGBT inverter technology ensures stable arcs and maintains a 60% duty cycle at 200A, enabling efficient operation during continuous welding. The 2T/4T/Spot welding modes can meet your specific needs.Safety Welding: The welder has overheat and overcurrent protection (thermal and current breakers). If the temperature or current exceeds the limit, the internal breaker will trip, stopping power to the drive motor while the fan keeps cooling the unit.Customer Support: BILT HARD is committed to providing high-quality products and exceptional customer service.
