MCU control system, responds immediately to any changes. High frequency and high voltage for arc igniting to ensure the success ratio of igniting arc, the reverse polarity ignition ensures good ignition behavior in TIG-AC welding. Avoid AC arc-break with special means, even if arc-break occurs the HF will keep the arc stable. Pedal control the welding current.
TIG/DC operation, If the tungesten electrode touches the workpiece when welding, the current will drop to short-circuit current to protect tungsten. Intelligent protection: over-voltage, over-current, over-heat, when the problems listed before occurred, the alarm lamp on the front panel will be on and the output current will be cut off. It can self-protect and prolong the using life. Double purposes: AC inverter TIG/MMA and DC inverter TIG/MMA, Excellent performance on Al-alloy, carbon steel, stainless steel, titanium.
For DC MMA, polarity connection can be chosen according to different electrodes. For AC MMA, magnetic flow caused by invariable DC polarity can be avoided. For DC TIG, DCEP is used normally (workpiece connected to positive polarity, while torch connected to negative polarity).
This connection has many characters, such as stable welding arc, low tungsten pole loss, more welding current, narrow and deep weld. For AC TIG (rectangle wave), arc is more stable than Sine AC TIG.
At the same time, you can not only obtain the max penetration and the min tungsten pole loss, but also obtain better clearance effect. 1X HF Tig torch torch. 1X3M 16MM2 Cable+ earth clamp. 1X3M 16MM2 Cable+ electrode holder.Item Processing Time: The processing time for a specific order varies with the product type and stock status.
