5.Loosen the socket head cap screw that holds the connector bar against the gun bushing.

Important: Do not attempt to completely remove the socket head cap screw.

6.Remove the outer wire guide, and push the gun bushing out of the wire drive. Because of the pre- cision fit, light tapping may be required to remove the gun bushing.

7.Disconnect the shielding gas hose from the gun bushing, if required.

8.Connect the shielding gas hose to the new gun bushing, if required.

9.Rotate the gun bushing until the thumb screw hole aligns with the thumb screw hole in the feed plate. Slide the gun receiver bushing into the wire drive and verify the thumb screw holes are aligned.

3.Press the trigger to feed the wire electrode through the gun and cable. For solid wire cut the electrode within approximately 3/8" (10 mm) of the end of the contact tip [3/4" (20 mm) for Outershield®].

4.When welding with gas, turn on the gas supply and set the required flow rate (typically 25-35 CFH; 12- 16 liters/min).

5.Connect work cable to metal to be welded. Work clamp must make good electrical contact to the work. The work must also be grounded as stated in “Arc Welding Safety Precautions”.

WARNING

•When using an open arc process, it is necessary to use correct eye,

head, and body protection.

10.Tighten the socket head cap screw.

11.Insert the welding gun into the gun bushing and tighten the thumb screw.

MAKING A WELD

1.Check that the electrode polarity is correct for the process being used, then turn the power switch ON.

2.Set desired arc voltage tap and wire speed for the particular electrode wire, material type and thick- ness, and gas (for MIG and Outershield®) being used. Use the Application Chart on the door inside the wire compartment as a quick reference for some common welding procedures.

-----------------------------------------------------------------------

6.Position electrode over joint. End of electrode may be lightly touching the work.

7.Lower welding helmet, close gun trigger, and begin welding. Hold the gun so the contact tip to work distance is about 3/8" (10 mm) [3/4" (20 mm) for Outershield®].

8.To stop welding, release the gun trigger and then pull the gun away from the work after the arc goes out.
