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 itself melt. The weld pool and the electrode are protected by
shielding gas.
Direct current
A higher current gives a wider weld pool, with better penetration into the workpiece.
Pulsed current
Pulsing is used for improved control of the weld pool and the solidification process.
The pulse frequency is set so slow that the weld pool has time to solidify at least
partially between each pulse. In order to set pulsing, four parameters are required:
pulse current, pulse time, background current and background time.
