1.Check that the drive rolls, feeder guide tubes and gun connector guide tube are appropriate for the electrode size being used. If necessary, change them per “Wire Drive Roll Kits” in this section.

2.Connect gun to gun connector making sure all pins and gas tube line up with appropriate holes in con- nector. Tighten gun by turning large nut on gun cable clockwise.

10 SERIES WIRE DRIVE WATER CONNECTIONS (FOR WATER COOLED GUNS)

10 Series Wire Drive: must have a K590-4 Water Connection Kit installed for water cooled guns. (See ACCESSORIES).

Using male quick-connect fittings, connect the water hoses to the coolant inlet and outlet on the back of the wire drive. Connect the other ends of these hoses to the appropriate ports on the water cooling units.

In the event the water line fittings on your water cooled gun are incompatible with the female quick connects on the front of the wire drive, male quick- connects (L.E. Part No. S19663) are provided in the Kit for installation on 3/16" (5 mm) I.D. hose (Customer to provide appropriate clamps). The feed- er connectors self seal when disconnected.

Synergic 7F Wire Drive (K679) :Must have a K682-2 Water Connection Kit installed. (See ACCESSORIES section of IM559).

Using hose clamps provided with the K682-2 kit, con- nect appropriate water hoses to the coolant inlet and outlet fittings on the back of the K682-2 Kit. Connect the other ends of these hoses to the appropriate ports on the water cooling units.

In the event the water line fittings on your water cooled gun are incompatible with the female quick connects on the front of the K682-2 Kit male quick- connects are provided with the kit for installation on 3/16 (5 mm) I.D. hose (Customer to provide appropri- ate clamps). The feeder connectors self seal when disconnected.

WARNING

CYLINDER may explode if damaged.

• Keep cylinder upright and chained to

support.

• Keep cylinder away from areas where it may be damaged.

•Never lift welder with cylinder attached.

•Never allow welding electrode to touch cylinder.

•Keep cylinder away from welding or other live elec- trical circuits.

BUILDUP OF SHIELDING GAS may harm health or kill.

• Shut off shielding gas supply when not in use.

SEE AMERICAN NATIONAL STANDARD Z-49.1, “SAFETY IN WELDING AND CUTTING” PUBLISHED BY THE AMERICAN WELDING SOCIETY.

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

Customer must provide a cylinder of shielding gas, a pressure regulator, a flow control valve, and a hose from the flow valve to the gas inlet fitting of the wire drive unit.

Connect a supply hose from the gas cylinder flow valve outlet to the 5/8-18 female inert gas fitting on the back panel of the wire drive or, if used, on the inlet of the Gas Guard regulator. (See Below).

Gas Guard Regulator - The Gas Guard Regulator is an optional accessory (K659-1) on these models.

Install the 5/8-18 male outlet of the regulator to the 5/8-18 female gas inlet on the back panel of the wire drive. Secure fitting with flow adjuster key at top. Attach gas supply to 5/8-18 female inlet of regulator per instructions above.
