ARCCAPTAIN TIG Welder AC/DC 200Amp with Pulse, Aluminum TIG Welder 110V/220V TIG Welder with Square/Triangular Wave/Stick/MMA/Spot MultiProcess DASH-ARC Welding Machine. POWERFUL 7-IN-1 TIG WELDER AC/DC: The Welder is capable of welding with TIG AC Square/TIG AC Triangular/TIG AC Pulse Square/TIG AC Pulse Triangular/TIG DC Pulse/TIG DC/STICK Methods. AC TIG is used in finesse welding various aluminum alloys, magnesium alloys, and other non-ferrous metals. DC TIG provides low-temperature control. You need precise welding for various types of steel: stainless steel, carbon steel, copper. PATENTED DASH-ARC TECHNOLOGY: The unique DASH-ARC technology patent improves arc striking speed from 200ms to 40ms, 99.99% arc striking success rate, which improves welding efficiency and gets better welding results. Digital constant current regulation technology ensures low noise and high stable arc quality at the full specification. PULSE & SQUARE & TRIANGULAR WAVEFORM: The ac/dc TIG welder is equipped to prevent the burning of materials and minimize material distortion from excessive heat input, as well as the triangular wave reduces the heat input effectively, so the weld forms rapidly. It is easy for thin metal welding; Square Wave can switch the polarity quickly, dynamic arc for a stable weld pool, a strong ability to clean aluminum oxide film, so it provides more precise welding on aluminum or aluminum alloy. DIGITAL WEDLING PARAMETER SET: MCU Digital control system makes this machine more reliable and stable. Parameters such as Pre-flow, Initial current, Up-slope, Peak current, Base current, Down-slope, Crater current, Post-flow, Pulse duty, AC frequency, AC balance, Pulse frequency, are easily adjustable, and 2T/4T/Spot welding TIG torch control and foot pedal remote control (not included) methods which improve good welding performance. The user-friendly and simple interface enables the operators to set it up easily and efficiently, data and dynamic output current will be displayed immediately. Spike withstanding IGBT saves space and weight. It’s only 12 kg(26.5lb). The ARCCAPTAIN AC/DC TIG Welder with Pulse, Triangular, and Square waveform is a versatile machine fit to help complete various precise projects. Whether you’re welding vehicle bodies, metal furniture, pipeline, sculpture, or thin plates, the TIG welder is unmatched for true hands-on craftsmanship. Precise Welding Parameter Adjustment.
