15 Welding method
15.1 Electrode
Before switch-on, ensure that neither
the electrode holder nor the elec-
trode is touching the welding table,
the workpiece or another electrically-
conductive object, to ensure that you
do not unintentionally ignite arcing on
switch-on. An unintentionally ignited
arc can damage the electrode holder,
the welding table, the workpiece and
the machine.
Switch on the system
 Press the On/Off button 28 for 2 sec. to switch
on the system.
 Press button 26 for at least 2 seconds.
9 The electrode symbol (LED 21) lights up.
 Use control knob 19 to set the desired welding
current.
Arc ignition
 Briefly touch the workpiece at the point to be
welded using the electrode and lift the elec-
trode a little.
9 The arc burns between the workpiece and the
electrode.
Pulses
 Press button 26 until the Pulses symbol (LED
23) lights up.
 Call up the secondary parameters (see "16 Sec-
ondary parameters" on Page 37).
 Select the "Secondary energy" secondary pa-
rameter (2.E).
01.22
 Set the desired secondary current value by us-
ing control knob 19. The setting value is based
on the main current I
 Select the "Pulse frequency" secondary param-
eter (PuF).
 Set the desired pulse frequency by using con-
trol knob 19.
 Select the "Pulse cycle duty" secondary param-
eter (PuB).
 Set the desired pulse duty cycle by using con-
trol knob 19. The setting value is based on the
main current I
Example: 60% corresponds to a mix of 60%
main current I
 Leave the secondary parameter menu.
‰ The calculated average current value is shown
on Display 31 during the welding process.

 Call up the secondary parameters (see "16 Sec-
ondary parameters" on Page 37).
 Select the CEL mode secondary parameter
(CEL)
 Set the value to "On"
9 The electrode symbol 21 flashes.
‰ The CEL mode electrode is active.
‰ The welding properties are only optimised for
CEL electrodes.
All other secondary parameters remain un-
changed.
