Description
and Applications |
|
H01 is an illuminate type electrode,
which is attaching importance to weld ability. Welding
of steel structures, vehicles, bridges, and the other
general structures made of mild steel. |

|
Guideline in Usage |
|
1. |
The
electrodes should be re-dried at 70
∼
120℃ for 30 ∼
60 minutes before use. Excessive moisture absorption
may result in some porosity and more spatters. |
|
2. |
Pay
attention not to exceed the range of proper currents.
Welding with excessive current not only lowers X-ray
performance, but also causes increase in spatter,
undercut and insufficient slag covering. |
