High strength machinable electrode for joining and building up on cast irons. Low amperage, smooth arc, minimum spatter and high resistance to cracking. For the repair of grey, S.G., nodular or ductile irons where higher strength is required. Also suitable for joining cast iron to mild steel (in conjunction with Mac Groove), pressure vessels, etc.

If allowed to become damp the electrodes should be re-dried for one hour at 150°C before use.
