Description and Applications |
|
HE309 is a lime-Titania
type electrode. Weld ability is excellent. Spatters are
less and crack resistance is good.
Welding of dissimilar
metals such as stainless steel 309S, 304 to carbon steel
or low alloy steel. |

Guideline in Usage
|
|
1. |
Preheat is
unnecessary. |
|
2. |
Keep the short
arc and low amperage. Weaving width should be
within 2.5 times electrode diameter. |
|
3. |
Electrodes should be re-dried at
250
∼
300℃ for one hour before use |
|
4. |
Remove dirt such
as oil and dust from the groove |
