Description and Applications |
|
HW12 PS-6 is a gas metal
arc welding wire by CO2 shielding. Arc is stable,
spatters are few, and the weld ability is excellent even
with a low current under 200A. Welding often involved
thin plates in all positions, especially in vertical
downward positions. It also shows better weld ability in
high speeds with currents less than 300A than with wires
of any other type. |

|
Guideline in Usage |
|
1. |
In
vertical downward welding, wire should be held
at an angle slightly more than a horizontal. |
|
2. |
Optimum arc
voltage should be selected in accordance with
welding current to maintain stable dip transfer
mode. If voltage is too high or too low, dip
transfer frequency will decrease. |
