Refer to Figure B.3.

4.Release the spring loaded thumbscrew and rotate the idle roll arm away from the wire feed drive roll. Ensure that the visible, stenciled size on the drive roll side facing you matches the wire size being used.

5.Carefully detach the end of the wire from the spool maintain tension on the wire. To prevent the spool from unwinding and do not release the wire until after step 5.

6.Cut the bent portion of wire off and straighten the first 4” (102 mm).

7.Thread the wire through the incoming guide tube, over the drive roll, and into the gun liner.

8.Close the idle roll arm and turn down the thumb- screw until the idle roller presses down firmly on the wire. (Now you may release the welding wire). Make sure the wire is positioned in the groove of the lower drive roll.

9.The spring loaded thumbscrew on the idle roll arm adjusts the pressure on the wire. Adjust pressure by turning the thumbscrew to prevent spool over- run, but still allow smooth and easy wire feeding. Start with the pressure set to an intermediate value. Readjust, if necessary. Slightly less pressure may be required when using 0.023 - 0.025” (0.6 mm) wire. If the drive roll slips while feeding wire, the pressure should be increased until the wire feeds properly.

WARNING

• When feeding the welding wire through the gun, the drive roll, the gun connector block and the gun contact tip are always energized rela- tive to work and ground.

10.Remove the gas nozzle and contact tip from the gun.

11.Turn the machine ON (“I”).

12.Straighten the gun cable assembly.

13.Depress the gun trigger switch and feed welding wire through the gun and cable. (Point the gun away from yourself and others while feeding wire.) Release the gun trigger after wire appears at the end of the gun.

14.Turn off the machine.

15.Replace the contact tip and nozzle. Refer to Figure B-4. Cut the wire off so that 3/8”(10mm) protrudes from the end of the tip.

16.Turn on the machine. The machine is now ready to weld.

SHIELDING GAS

When using the MIG process, you will need a cylinder of carbon dioxide (CO2) or argon-carbon dioxide mixed shielding gas

The preset regulator supplied with the machine is designed for use with argon blend gas. An adapter and plastic washer are needed for using 100% CO2 gas. This adapter is available from your local gas sup- plier.

1.Open the cylinder valve slowly a fraction of a turn. When the cylinder pressure gauge pointer stops moving, open the valve fully.

2.Keep the cylinder valve closed, except when weld- ing. When finished welding:

•Close the cylinder valve to stop gas flow.

•Depress the gun trigger briefly to release the pressure in the gas hose.

•Turn off the machine.
