Description and Applications |
|
HE308M is a high welding efficiency
stainless steel electrode with mild steel core wire, for
welding of 18﹪Cr－8﹪Ni
stainless steel. With thicker coating flux, it shows
excellent weld ability under higher amperage. Suitable
for flat welding. |

Guideline in Usage
|
|
1. |
Electrodes should be re-dried at
250
∼
300℃ for one hour before use |
|
2. |
Excessively wide weaving may cause welding
defects. Keep weaving width to less than 2.5
times electrode diameter. |
| 3. |
Remove dirt such
as oil and dust from the groove |
