1. This kind of welding machine applies digital control and is full featured. All functional parameters can be preset accurately. The melting width of the weld and the ripple coefficient of the weld bead can be controlled freely to avoid the strike of high current during arc ignition. In the end of the welding process, the crater can be filled. The welding machine performs well when welding sheet metal of all kinds of thickness.

2. This kind of welding machine has excellent adjustability. It can serve four different welding purposes. It is able to perform manually operated arc welding and DC argon arc welding. The welder is quite easy to use.

3. This kind of welding machineemploys high frequency and high voltage arc ignition method. The probability of successful arc ignition is almost 100%. The arc is stable, soft, centralized and elastic. All the above mentioned advantages ensure high welding quality.

4. The pulsed-current, pulse frequency and pulse width can be adjusted arbitrarily in a wide range to meet the demands of different kinds of welding.

5. Manually controlled arc welding has little solder spatter. The welding current is stable which greatly improve the reliability and shaping of weld.

6. Passive power factor correction is adopted in the welding machine to raise the power factor.

7. This kind of welding machineemploys water cooling and is equipped with gas welding machine with double protection so as to prolong its service life effectively.

8. This kind of welding machinehas gone through pickling, phosphating and electrostatic powder spraying. The paint film is smooth, solid and resistant to erosion and fracture.

Sunye mainly provides industrial TIG welders, and is a reliable pulsed DC TIG welder manufacturer and supplier, there are a variety of industrial welders for welding thin sheet metal and thick steel plates. TIG welder, full name of tungsten inert gas welding, also called as gas tungsten arc welding machine, if you need industrial welders for pressure vessel welding and stainless steel welding, please contact us.
