7.3 Voltage Control (CV) Welding
The inductance value affects welding behaviour, especially regarding arc width.
With a negative value, the weld will tend to look a little rougher and will have a smaller arc
width, which leads to greater penetration power.
With positive values, the weld may appear a little smoother and the arc will be wider.

- Star welding.
NOTE: Please refer to chapter A - Appendix, where the tables are presented with the parameter
values that can be adjusted per welding process for the DC 164, DC 204 and DC 224.
8. ERRORS DESCRIPTION
Er1 - Equipment overheating - Do not switch off the machine. Allow the equipment to ventilate
until the error disappear.
Er6 – Phase failure - Switch off the power supply to the machine and the corresponding
machine circuit breaker.
Check the connection of the power cable to the electrical installation on all 3 phases.
Er11 – Communication from the machine to the external device - Switch the machine off and on
again. If the error persists, contact your supplier.
For DC 224 (See items in Fig. 1 B)
Voltage
Adjust the electrical voltage value.
[-1 0 1] – [rough inductance; normal inductance; soft inductance].
