• Unscrew the clamping cap.
• Remove the existing tungsten electrode from the collet and insert the new electrode in.
• Insert the collet into the torch.
• Scrrew the clamping cap tightly.
• The ceramic gas nozzle and the tungsten electrode diameters should be selected according to the working
current and the shape of the work-piece. Therefore the collet, the collet body must be matched with the
diameter of the tungsten electrode.

• Switch ON the machine by following the steps.
• According to the polarity of the electrode to be used, insert the electrode holder cable and the earth clamb cable
plugs into their appropriate sockets and tighten them by turning clock-wise.
• Connect the earth clamp tightly to the work-piece as close as possible to the welding area.
• Adjust the desired current and the machine is ready to weld.
• Below table is given as a reference for currrent adjustment of mild steel electrodes, please refer to the electrode
manufacturer’s recommendations.
