Polarity Change - ESAB Caddy Mig C200i Manual De Instrucciones

GB
available, all graphics from the right side of the display disappears, and only number
from 00 to 10 is displayed . This number corresponds to the virtual inductance. 00
means that virtual inductance is small and the welding arc is "sharp", 10 means that
the virtual inductance is high and the welding arc is "soft".
The value of the virtual inductance can be set by means of the knob 8. Default
setting is 05.
Recommendations:
When the CO is used it is recommended to set set lower "inductance" then 05,

The interface goes back to the regular appearance 10s after the last movement of
the knob 8 or pressing pushbutton 7. Operator can accelerate the return to the

Polarity change

The machine is delivered with the welding wire connected to the plus pole. Some
wires, e.g. gasless cored wires, are recommended to be welded with negative
polarity (welding wire connected to the minus pole and return cable connected to the
plus pole). Check the recommended polarity for the welding wire you want to use.
The polarity can be changed inside the wire feed cabinet:
1. Switch off the machine and disconnect the mains cable.
2. Bend the rubber covers back to give access to the cable lugs.
3. Remove the nuts and washers. Note the correct order of the washers.
4. Change the position of the cables to the desired polarity (see marking).
5. Install the washers in correct order and tighten the nuts to spanner tightness.
6. Make sure the rubber covers are covering the cable lugs.
