Description: J555 is a vertical downward electrode with high cellulose potassium coating. AC and DC dual-purpose. when welding downward, molten metal and slag will not flow down. It has great arc force and penetration. Bottom welding can be formed on both sides and has high welding speed. Application: Used for welding low alloy steel pipes.
