Major functions |
|
 |
Narrow bead and minimized deformation ← by heat concentration of high temperature, high energy density plasma |
|
|
No spatter created ← by plasma arc formed from pilot arc |
|
|
Allows I-type butt welding ← no edge preparation is needed by application of key-hole welding |
|
|
Optimal for automatic welding ← plasma gases protect electrode, resulting in extended life of electrode. |
|
|
Allows welding for zinc plated and brass sheets ← electrode inside the nozzle is not exposed to hume pipe. |
