BASW-9900X-T technology is revolutionary compared to others in the industry. With advanced and innovative technology, the operating voltage is compensated automatically. When the welder is connected to an AC380V power supply, the system compensates for variations of the main supply voltage and ensures a constant current level to achieve a high quality performance. The large digital graphic LCD display with blue backlight is easy to learn and read. A uniquely designed gun cable support arm allows flexible movement with 360° rotation and a stepless current control ensures the stability of the current in different welding conditions. This unit is equipped with an efficient integrated circuit that produces an accurate readout. A variety of extension arms is designed to accommodate any welding job. With 10 preset weld programs and 60 built-in memory functions, this unit is an excellent choice for body repair work and spot welding tasks.
