Inverter DC Pulse TIG Welder

For design of WSM-400 inverter DC pulse TIG welder, advanced soft-switch inverter technology and micro-computer digital control technology are adopted, thus vulnerableness of IGBT is resolved, making the control board design more easily. Besides that, control accuracy and speed are dramatically improved and this machine is pretty ideal for sheet metal welding. Generally, there are 9 control knobs for this product and they are distributed in two rows on the control panel of the front of the WSM-400 inverter DC pulse TIG welder. There are 4 knobs in the upper row and they are all for current control. To be more specific, knobs for current up slope time and current down slope time are distributed on both sides and in accordance to the standard, the regulation range is 0 to 10s. In the middle, there are knobs for welding current and base current with the range of 5 to 400A. Besides that, there are 5 knobs in the lower row and from left to right, they are knobs for start current, pulse frequency, duty cycle, crater current and post flow time.
