Major functions |
|
 |
Prevent creation of spatters → uses pulse power |
|
|
Prevent burn-through → decreases temperature of droplet by increase of EN ratio |
|
|
Reduce deformation → decreases heat input by increase of EN ratio |
|
|
Ensure high speed welding → allows higher wire melting speed at constant welding current than DC pulse |
|
|
Save energy → allows use of lower current at constant wire melting speed than DC pulse |
|
|
Control depth of penetration → decreases penetration depth by increase of EN ratio |
