Igniting the arc
Igniting the arc
using high fre-
quency
(HF ignition)
CAUTION!
Risk of injury due to an electric shock
Although Fronius devices comply with all relevant standards, the high frequency ignition
can transmit a harmless but noticeable electric shock under certain circumstances.
► Use prescribed protective clothing, especially gloves!
► Only use suitable, completely intact and undamaged TIG hosepacks!
► Do not work in damp or wet environments!
► Take special care when working on scaffolds, work platforms, in forced positions, in
tight, difficult to access or exposed places!
HF ignition is activated when the setup parameter "IGn" is set to "on".
The HF ignition special indicator illuminates on the control panel.
Unlike with contact ignition, there is no risk of contaminating the tungsten electrode and
workpiece during HF ignition.
Procedure for HF ignition:
Position the gas nozzle at the ignition
point so that there is a distance of ap-
proximately 2 to 3 mm (5/64 - 1/8 in.)
between the tungsten electrode and
the workpiece. Distance exists.
Increase the tilt angle of the welding
torch and press the torch trigger accor-
ding to the selected operating mode
The arc ignites without coming into contact
with the workpiece.
