1. The most professional design of TIG welder, with current
presetting and arc ignition/current up time/current down time
adjustable” functions, reducing efficiently the burning loss of
tungsten electrode and components pollution.
2. Applying 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.
3. Unique Separateness Heat Sink Technology offers this machine the
most effective cost; it is the best choice of TIG welder.
4. High duty cycle and high protection design ensure safe and
reliable working performance.
5. In 40℃ condition, WS-315D output current: 250A@100%, WS-400D:
370A@100%; 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
9. Industrial packaging and protection are tested by drop test,
suitable to long-distance transportation.
10. ASK unique design, elegant appearance and easily recognize.
