High quality cast iron electrode with very low impurity rate.Lot of 50 pieces.DimensionsDiameter: 2.5 mmLength: 300 mmUse: Minimum voltage (A): 60 Maximum voltage (A): 100Welding all positions.To apply moderate amperage and the shortest arc length possible. Place stringer beads (no weaving). Maximum length 50 mm. To hammer the bead immediately after welding while it is still dull red. To cool slowly after welding, in the saw, vermiculite or oven. Electrodes rectification: 200 ° C, 2 hours. Classification: SFA / AWS A5.15 - ENiFe-CI - EN ISO 1071 EC - NiFe-1 3 Easy priming Welding procedure for cast iron: Dirt, molded skin, paint, oil and grease must be removed Cold welding can be applied in many cases when using this electrode. However, preheating to around 250 degrees is advised.
