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