AUXILIARY EQUIPMENT CONTACTS

The power for 115 volt AC auxiliary equipment can be obtained from the terminals inside the LN-9 GMA con- trol box. The contacts are “hot” whenever the trigger is pressed or the unit is welding. The current draw of this circuit must not exceed 1/4 ampere.

WARNING

TURN THE INPUT POWER TO THE POWER SOURCE OFF AT THE DISCONNECT SWITCH BEFORE PERFORMING THE FOLLOWING WORK.

LN-9 GMA MODEL:

Install 1/4” quick connect terminals to the leads from the auxiliary equipment. Route the leads to the termi- nals marked #32A and #7 which come through the rec- tangular hole in the control section sheet metal near the wire feed motor.

LN-9F GMA 2-ROLL AND 4-ROLL MODELS:

Install terminals for #6 screws to the leads from the auxiliary equipment. Route the leads to the terminals #32A and #7 on the terminal strip on the inside bottom of the control box.

NOTES:

1.The K418 and K419 burnback timer does not delay the opening of the auxiliary equipment contacts. If you want to continue power to auxiliary equipment during the burnback time, this can be accom- plished only if you are using an R3S, DC-400 or DC-600 power source. Connect the 115 volt AC auxiliary equipment leads to #4 and #31 on the power source terminal strip. The auxiliary equip- ment power requirements should not exceed 15 watts.

This alternate connection cannot be used with the DC-250 or CV-400, 500-I Power Sources.

2.If the LN-9 GMA gas solenoid valve is not required, the gas solenoid terminals (#32A and #7A) may be used in conjunction with the K418 GMA Timer Kit to obtain pre-weld and/or post-weld timing functions for 115V AC auxiliary equipment. However, the gas solenoid must be disconnected and the auxil- iary equipment current draw must not exceed 1/4 ampere.

OPTIONAL EQUIPMENT AND ACCESSORIES

POWER INPUT CABLE ASSEMBLIES (K196, K595, K596)

Required to connect wire feeder to power source. Includes multiconductor control cable and the proper size electrode cable for the welding current to be used. Specify length and maximum welding current.

•K196 Input Cable Assemblies - For power sources with terminal strip wire feeder connections and stud output terminals.

•K595 Input Cable Assemblies - For power sources with MS-type (Amphenol) wire feeder receptacle and stud output terminals.

•K596 Input Cable Assemblies - For power sources with MS-type (Amphenol) wire feeder receptacle and Twist-Mate™ output connectors.

WIRE REEL STANDS AND MOUNTINGS

50-60 LB. WIRE REEL MOUNTING STAND (K303)

The assembly includes a framework to which is attached the 50-60 lb. wire reel, a mounting spindle, a dust shield, a lift bail, and a cable clamp for fastening the input cable assembly. It is easily mounted to the basic wire feed unit by three bolts. The reel mounting spindle is the pull knob type with a built-in brake.

The brake pad is adjustable for proper braking at low or high wire feed speeds.

50-60 LB. READI-REEL®MOUNTING STAND (K445)

The assembly includes a framework to which is attached a 2" O.D. spindle with adjustable brake and 50-60 lb. Readi-Reel Adapter. Includes a lift bail and cable clamp for fastening the input cable assembly, and easily mounts to the LN-9 GMA feeder. Does not include dust shield.

Can also be used for up to 60 lb. spools with 2" I.D.
