Description:
CHE425
is a high cellulose
potassium type welding rod for mild steel. It is suitable for vertical-down
welding and lap welding for sheet 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.
