GMAW Shielding Gas

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.

WARNING

ELECTRIC SHOCK can kill.

• Do not touch electrically live parts such

as output terminals or internal wiring.

•When inching with gun trigger, electrode and drive mechanism are “hot” to work and ground and could remain energized several seconds after the gun trigger is released.

•Turn OFF input power at welding power source before installation or changing drive roll and/or guide tubes.

•Welding power source must be connected to system ground per the National Electrical Code or any applicable local codes.

•Only qualified personnel should perform this installation.

Input Cable: LN-10 Control to Power Source

K1501-10 (Control Cable only)

Consists of a 9-conductor control cable with 14-pin control cable plug, without electrode cable, and is available in a length of 10 ft. (3 m).

With input power disconnected from the power source, install the input cable per the following:

1)Connect the end of the control cable with the 14- pin cable plug to the mating receptacle on the power source.

2)Connect the electrode lead to the power source output terminal of the desired polarity.

3)Connect the 9-socket plug of the control cable to the mating receptacle on the bottom of the LN-10 control box.

4)Slip the current sensor cover off enough to expose the input connector stud. Connect the electrode cable from the power source to this stud with the nut provided, then reclose the current sensor cover.

Work Cable

Connect a work lead of sufficient size and length (per the following table) between the proper output termi- nal on the power source and the work. Be sure the connection to the work makes tight metal-to-metal electrical contact.
