3 TIG Mode, DC, DC Pulse, AC, AC Pulse
There are four TIG modes available.
All TIG modes are done with torch electrode
connected to negative output.
DC TIG provides a constant DC output
suitable for welding most metals except
Aluminium.
AC TIG provides an alternating Current
output which is suitable for Aluminium
welding. Aluminium material develops an
oxide coating which is an insulator, the AC
current provides some positive current which
cleans the oxide from the weld surface.
Both AC and DC can use pulse mode where
the weld current can be pulsed high low.
when the required TIG mode has been
selected, the specific weld parameter
needs to be selected.
