CHANGE OF SECONDARY WELDING PARAMETERS
The welder is set to factory default settings. For most jobs it is not advisable to
change secondary parameters. The secondary parameters for manual and
synergic methods are identical.
1. Press button
V20
and encoder
V5
simultaneously to enter the secondary
parameters menu.
2. Use encoder
V5
to select the parameter (ISP, PrG, PoG, brn, SCu, bCu,
ECu, tuP, tdo, t S, t E, CAL), use encoder
V16
to set the desired value.
3. Press encoder
V5
to confirm the selection.
4. Secondary parameters are common to the manual and synergistic
methods. The synergistic method allows for multiple secondary
parameters to be set.
