Features Multi-functions: AC Square wave TIG, DC pulse TIG, DC TIG, MMA and Spot TIG welding. Microprocessor control technology. Parameters in panel are set by coordinate-type touch key; and single-knob makes the operation simple and clear. Many adjustable parameters under each of the five welding states. All parameters under the five welding states can be stored in Memory channel. Protective functions: overheat, over-current and under-voltage, etc.

Features Soft-start ignition. 2/4-step welding modes switch. Adjustable arc force, crater current, crater voltage, welding current and welding voltage. Welding wires dia. Selection. Welding voltage and welding current can be preset and displayed digitally. Fast-feed by spot. Protective functions: overheat, over-current, under-voltage and power phase absence, etc.
