Cel 6010
Optimized arc characteristics for cellulose electrodes, such as 6010.
TIG (GTAW) welding
TIG welding, also called gas tungsten arc welding (GTAW), melts the metal of
the workpiece using an arc struck from a tungsten electrode that does not melt.
The weld pool and electrode are protected by shielding gas.
For TIG (GTAW) welding, the welding power source must be supplemented with
the following:
• TIG (GTAW) torch with gas valve
• Argon gas cylinder
• Argon gas regulator
• Tungsten electrode
This power source performs
Live TIG (GTAW) start
.
The tungsten electrode is placed against the workpiece. When lifted from
workpiece, the arc is struck at a limited current level.
Voltage Reduction Device (VRD)
The VRD function ensures that the open-circuit voltage does not exceed 35 V
when welding is not being carried out. This is indicated by a lit VRD indicator on
the panel. Contact an authorized ESAB service technician to activate this
function.
