1. Try to avoid Welding Tungsten electrodes continuous welding for a long time, stay for a period of time to prevent the tungsten electrode from overheating.
2, try to avoid welding the wolfram tungsten electrode in the vertical hole, in order to reduce the contact area of the welding electrode, so as to avoid overheating.
3. In the welding process, do not use side faucet and transverse pressure welding, so as to avoid overheating of the welding head of tungsten electrode.
4, the use of special flux can effectively reduce the risk of overheating tungsten electrode.
