Inserting Electrode Wire And Braking Torque Adjustment - Lincoln Electric Compact 220 Operating Manual

- Check if the drive roll bears stamped on the outer side the diameter
corresponding to the wire used. Otherwise, unscrew the screw holding
the roll and turn it or replace it.
- Every roll is provided with two grooves fitted for feedering of wire with
different diameters. Special rolls are avaiable for cored and aluminim
wires.
- Realse by the suitable lever the pressure roll turning on the ball bearing
and lift it.
- Put the wire inside the fitting inlet guide and let it out through the torch
adapter.
- Lower the lever regulating the pressure by the adjustment nut.
The best thing is to keep the right pressure as it avoids by roll slipping.
- An excessive pressure causes wire distortion, entanglements at the
protection entry and tear of the feeding motor.
- Too low pressure may cause welding irregularities.
- Connect the torch to the torch adapter and make sure the wire runs
correctly inside the liner of the torch cable.
- Take off the gass guide from the torch extremity and unscrew the con-
tact tip.
- Take the wire come forward as far as it comes out of the torch.
