Welding Data Display; Welding Parameter Setting; Arc Ignition; Hf Ignition - EWM Tetrix 352 Synergic Operating Instructions Manual

Design and function

Arc ignition

5.13.5 Welding data display

The following welding parameters can be displayed before (nominal values), during (actual values) or
after welding (hold values):
Parameter
Welding current
Parameter times
Parameter currents
Material thickness
Welding voltage
JOB number
Program number
When the settings are changed (e.g. welding current) after welding when the hold values are displayed,
the display will be switched to the relevant nominal values.
If the "Program number" signal light is on in addition to the "Material thickness" signal light, the user is in
program mode (programs 1-15, , - See 5.19 Welding programs chapter).
If the "JOB-number" signal light is on in addition to the "Material thickness" light, the user is in a JOB in
the free memory (JOB 128 to 256, - See 5.20.2 Creating a new JOB in the memory or copying a JOB
chapter).

5.13.5.1 Welding parameter setting

During the welding parameter setting process, the parameter value being set is displayed on the left-hand
display. The right-hand display shows the "Factory setting" or a variation of it upwards or downwards.
Displays, e.g. when setting the ignition current, and their meanings:

5.14 Arc ignition

5.14.1 HF ignition

The arc is started without contact from high-voltage ignition pulses.
a) Position the welding torch in welding position over the workpiece (distance between the electrode tip
and workpiece should be approx. 2-3 mm).
b) Robot start signal (high voltage ignition pulses ignite the arc).
c) Ignition current flows. The welding process is continued according to the operating mode selected.
End the welding process: Robot stop signal or other signals depending on the operating mode
selected.
