IGBT inverter WS-400 argon arc welder TIG&MMA combined welder Product Presentations:

Main Characteristics

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. IGBT inverter WS-400 argon arc welder TIG&MMA combined welder, 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 voltage testing.

9. Industrial packaging and protection are tested by drop test, suitable to long-distance transportation.

10. Unique design, elegant appearance and easily recognize.
