EN ISO 17632-A T 50 2 ZCrNiCu P M21 1 H10

Notes on Usage

Welding Positions:

1. Proper preheating(50~150℃, 122~302℉) and interpass temperature must be used in order to release hydrogen which may cause cracking in weld metal when electrodes are used for medium and heavy plates.
2. One-side welding defects such as hot cracking may occur with wrong welding parameter such as high welding speed.
3. Use Ar-20~25% CO2 gas.

4. Use DC(+)

Applications
