WSEM series of digital controlled IGBT inverter (square wave) DC/AC pulse TIG welding machine

Features:

1.Advanced soft switch inverter technique could solve the IGBT easily broken problem.

 2. The microcomputer digital controlled technique increases the control accuracy and speed, simplifies the design of the main control panel, and increases the reliability of products.

 3.The human-computer interface makes the process of parameters adjustment simple and covenient, and also have memory function.

 4. The adjustment range of cleaning area is wide ,getting the optimal welding parameters.

 5.Tungsten’s abrasion is extremely low, reducing total labor hardness, and enhancing production efficiency.

 6.With excellent weld shape, this series are the ideal type for aluminum welding.

 7.Using foot pedal switch control the welding current.
