GRAND

TIG 400

ACDC PULSE 

Overview

2.1 

Features

�   IGBT module inverter technology for smooth & stable output, increased reliability and high 

     duty cycle.

�   Phase loss protection for automatic shut down if power supply phase loss occurs, 

     to prevent damage.

�   Integrated heavy duty industrial trolley and water cooler (optional). 
�   Lift TIG and HF start modes for versatility when welding around sensitive electronic equipment.
�   Adjustable arc force, hot start & anti stick control for greater control and ease of use when 

      MMA welding. 

�   Electronic HF TIG arc ignition system for contamination free and easy arc starting with low 

     EMF interference.

�   2T/4T trigger control.
�   AC waveforms include square wave, sine wave, triangular wave.
�   AC balance control monitors the oxide and helps better cleaning during aluminum welding
�   Dual digital display meters for  accurate pre- setting and feedback of welding parameters & 

      output.

�   Up/ Down Button Remote Control on torch. (optional)
�   Wireless Remote Control and Wire / Wireless Foot Pedal. (optional)
