CHE425

Cellulose Electrode For Vertical-down Welding Mild Steel

CHE425 is a high cellulose type electrode for welding mild steel.it is suitable for vertical-down welding for sheet metal structures.Such as smoke pipes, wind pipes, oil tanks of transformer, outside cover of vehickles,etc.it is not good for wide weave when welding and it is not suitable for multi-layer or face widing.
