Steps of scraping arc
Steps of scraping arc
Stricking arc of TIG operation
:
when tungsten electrode touches the workpiece
,
the
short-circuit current is only 28A . After generating arc, current can rise to the setting welding
current.If the tungesten electrode touches the workpiece when welding, the current will drop to
5A within 2s, which can reduce the tungsten spoilage farthestly
,
prolong the using life of the
tungsten electrode
,
and prevent tungsten clipping.
●
When TIG operation,
the shielded gas is inputted
to welding gun directly,
and the method of lifting
arc is scraping arc.
ARC160
When in TIG operation, the
shielded gas is fed directly into
to the welding gun in readiness
for the lift arc process.
1. Place welding gun
at an angle
2. Scrape the electrode
with the workpiece
3. Lift arc
Steps of scraping arc
Striking arc of TIG operation:
When tungsten electrode touches the workpiece, the short-circuit current is only 28A.
After generating arc, current can rise to the setting welding current. If the tungsten
electrode touches the workpiece when welding, the current will drop to 5A within 2
seconds, which can further reduce the tungsten spoilage and extend the life of the
tungsten electrode and prevent clipping.
