Uses: Suitable for all kinds of crusher. Pulverizer, hammer, jaw, bucket fighting, bulldozers and other easy-to-wear parts surface surfacing. Surfacing hardness: HRC> 50

Reference current electrode diameter 3.2 4.0 5.0

90 180 ~ 120 150 ~ 180 180 ~ 220

Precautions: 

1, if the electrode damp, should be 300-350 ℃ baking 1h.

2, if the material carbon equivalent higher, the workpiece after appropriate preheating, slow cooling after welding.

3, surfacing should adopt a small current, the effect is better.
