Oerlikon Overcord Z description: OVERCORD Z is a medium-thick rutile-cellulosic general purpose MMA electrode. Suitable for structural steelwork, workshop and maintenance welding in all positions. Good gap bridging, easy striking and restriking. The slag is generally self-releasing, the weld beads are smooth and slighty concave, blending into the base plate without undercut. Used for welding galvanised steels, there is a tolerance to impurities in the welding zone. OVERCORD Z has a softer arc than OVERCORD.
