25.HF/Lift TIG slector
Select between a lift start or High Frequency (HF) start.
HF start is ideal for both AC and DC starts. HF start
allows the arc to be start-ed without contacting the metal.
Simply place the tungsten above the metal about 1/8” or
less, and press the torch switch or foot pedal and the
arc will start momentarily, after a brief gas flow period.
HF can cause interference with other electronic devices.
Lift start is an alternative method of starting an arc
where HF is problematic. Do not use this method
with AC because contamination of the tungsten will occur
unless the arc is struck on a copper strip first and the arc
transferred to the weld area. Lift start is accomplished
by touching the metal with the tung-sten and then
quickly lifting the tungsten when the torch switch or foot
pedal is pressed. If done properly, an arc will be drawn.
Note: This is not the scratch start method where the
tungsten is rubbed across the surface of the metal to
draw an arc.
