seems to feed smoothly without slipping.
4. Close the wire drive cover on the spool gun.
5. When set correctly, there should be no slippage between the wire and the drive roller under
normal conditions.

Adjusting the Spool Position

Before you begin welding, you may want to adjust the position of the spool so it is most comfortable for
you. There are three positions to choose from. To change the position of the spool:
1. With a flat tipped screwdriver, loosen the screw connecting the spool casing to the gun.
2. Pull the casing far enough away from the gun to allow the casing to rotate.
3. Rotate the casing to one of the three available positions, making sure the grooves on the gun
are aligned with the grooves on the casing.
4. Push the casing and the gun back together.
5. With a flat tipped screwdriver, tighten the screw which connects the spool casing to the gun.

Welder Controls

With welders in the digital series, thanks to a special electronic card it is possible to externally adjust
the welding parameters. The main purpose of these units is to make adjustment of these parameters
very easy.
The microprocessor control handles the functions of the p.c.board that are viewed by means of LED's
while a digital display shows the parameters set and welding current. Units may be used either with the
standard torch (supplied with them) or with the Spool Gun.
