1.With digital display and current presetting.
2.The function of arc ignition , current up time/current down time adjustable.
3.Reduce the influence of the tungsten electrode burning loss and components pollution.
IGBT inverter technology can save energy; work quickly and welding current is stable, obviously improves the efficiency. Combining with MMA function , suitable to all electrodes welding.
4.High duty cycle and high protection design ensure safe and reliable working performance.
5.In 40℃ condition, WS-315D output current: 250@100%duty cycle; WS-400D: 370A@100% duty cycle; WS series is the standard industrial TIG and MMA welder which is suitable to severe environment and heavy duty.
6.Provided with intelligent fan, which will stop working after the machine does not work for 5-6 minutes; as soon as the machine starts to work, the fan will return to work.
7. Provided with excellent protection, such as over voltage, under voltage, over heat and default phase, ensures the safely and greatly reducing the fault rates.
8.Excellent adaptability in unstable power grid, such as speed change and drop voltage, disturbing pulses, passing high and low voltage testing.
