Symbol and Function explanations

TIG welding
TIG welding melts the metal of the workpiece, using an arc struck from a tungsten elec­
trode, which does not melt itself. The weld pool and the electrode are protected by
shielding gas.
Parameter settings
1. Slope up
2. Welding current
3. Slope down
4. Gas post flow time
Slope up
The slope up function means that, when the TIG arc strikes, the current rises slowly
to the set value. This provides `gentler' heating of the electrode, and gives the
welder a chance to position the electrode properly before the set welding current is
reached.
Welding current
A higher current produces a wider weld pool, with better penetration into the
workpiece.
