-MAKE SURE TO TURN OFF THE GAS CYLINDER VALVE WHEN DONE WELDING.

ALIGN AND SET THE DRIVE ROLLER Before installing any welding wire into the unit, the proper sized groove must be placed into position on the wire drive mechanism.

Change the drive roller according to the fol- lowing steps:

1.Remove the drive tension by unscrewing tl_e tension adjusting screw (ALL THE V_AY in a counterclockwise direction). The drive tension screw will come loose, allowing you to pull the drive tension arm up away from the drive roller. Make sure

to keep the screw and the spring in place with the drive tension arm.

2.If there is wire already installed in the welder, roll it back onto the wire spool by hand-turning the spool counter-clockwise. Be careful not to allow the wire to come out of the rear end of the gun without holding onto it or it will unspool itself. Put the end of the wire into the hole on the outside edge of the wire spool and bend it over to hold the wire in place. Remove the spool of wire from the welder.

3.Loosen the drive roller set screw with the

provided hex wrench and pull the drive roller off the drive shaft.

Note: The drive roller has two wire size grooves built into it. When installing the drive roller the number stamped on the drive roller for the wire size you are using should be fac- ing away from you. If you can read the wire size you are using on the drive roller, it is installed backwards. Use only the proper size drive roller when using your welder.

,Find the side of the drive roller that is stamped with the same wire diameter as that of the wire being installed (see Figure 5, and if in metric, see DESCRIP- TION). Push the drive roller onto the motor shaft, aligning the set screw with the flat side of the drive shaft. Make sure the side stamped with the desired wire diameter is away from you.

5.Slide the roller onto the shaft so that the groove in the roller lines up with the inlet tube and the welding gun liner.

6.Tighten the set screw, while holding the drive roller in place.

INSTALL THE WELDING WIRE

I f]WARNING

Electric shock can kill! Always turn the

POWER switch OFF and unplug the power

cord from the ac power source before installing wire.

Be very careful when removing the welding nozzle. The contact tip on this welder is

electrically hot as long as POWER is turned ON. Make certain POWER is turned OFF.

1.Remove the nozzle and contact tip from the end of the gun assembly.

2.Make sure the proper groove on the drive roller is in place for the wire being installed. If the proper groove is not in place, change the drive roller as described above.

3.Unwrap the spool of wire and then find the leading end of the wire (it goes through a hole in the outer edge of the spool and is bent over the spool edge to prevent the wire from unspooling), BUT DO NOT UNHOOK IT YET.

4.Place the spool on the spindle in such a manner that when the wire comes off the

spool, it will look like the top illustration in Figure 6. The welding wire should always

come off the top of the spool into the drive mechanism.
