The Prince???XL Torch comes standard with a poly lined conduit, for running aluminum wire. The longer ??? tting with a shallow groove is used on the torch end. A set screw located on top of the torch handle secures the conduit in

Prince XL?? - Owner's Manual - Page 3

place. A small spool liner (MK P/N 003-0198) is used on the spool gun and held in place by the same set screw.

GAS HOSE

The gas hose is secured over the barbed gas ??? tting with a tie wrap. The cabinet end of the gas hose uses our standard gas ??? tting (1/8??? - 27 nps), whereas the spool gun uses a 5/8??? - 18 IAA RH male gas ??? tting.

ELECTRIC CABLE

A seven conductor control cable is used on the Prince??XL Torch. The torch end of the control cable is secured to the torch with a boot clamp and plugged into the pot assembly and micro switch connectors. Slack is left in the electric cable as it exits the back of the torch to prevent cable breakage. The cabinet end has a seven pin "W" clocked amphenol connector. See page 22 for torch electrical connections.

INSTALLING SPOOL ASSEMBLY (P/N 003-2090)

Loosen the screw that secures the conduit through access hole located on top right rear handle with a 1/16" Allen wrench.

Conduit Securing Screw

Remove conduit by pulling it out of the back of the gun.

2 Screws

Spool Liner

Install spool liner, and secure with screw.

Remove both rear handle screws, and secure spool canister with longer screws provided.

SPOOL GUN SETUP

LOADING ELECTRODE WIRE

Unscrew, and remove spool cover.

Apply tension to drive rolls, so the wire will be picked up and fed through the contact tip.

Straighten out ??? rst six inches of wire and push through liner.

Jog trigger until wire is picked up by drive rolls and fed through contact tip.

Hold brake assembly back towards top of gun, load spool onto shaft with wire coming off the bottom of the spool. Release brake assembly to rest on wire surface.

Replace spool cover, making sure opening is over liner.

Note:

The brake paddle assembly is designed to automatically control spool drag and keep the wire from jumping off the spool.

the slave motor in the cabinet, combined with the pull of the torch motor, causes the wire to literally ??? oat friction-free through the wire conduit. The 24VDC torch motor is controlled by a 3-3/4 turn potentiometer in the torch handle.

BARRELS

AIR/WATER COOLED

The Prince?? XL air cooled systems come standard with a straight air/water cooled barrel assembly. An optional curved air/water cooled barrel assembly (LE P/N KP2298-2, MK P/N 003-2152) is also available. In cases where these barrels need to be extended or the tip threads have been damaged, a Tip Extender (LE P/N KP2244-1, MK P/N 621-0424) can be adapted. The same tips and threads can be used, however a longer Te??? on liner (LE P/N KP2226-1; MK P/N 931-0137) is required.

BARREL REMOVAL AND INSTALLATION

To remove a barrel assembly, loosen the patented EZ Lock??? Taper lock nut assy MK P/N 003-2572 3/4 to 1 turn. This will push barrel away from the body far enough so that it may be pulled out of the body.

To replace a barrel assembly, take care not to damage the ???O??? rings when inserting into the body. Open the drive and idler roll door and seat the barrel assembly until the inlet guide is almost touching the drive and idler roll and the rear face of the barrel is ??? ush with the aluminum body block. Tighten taper lock nut assembly ??? rmly so that barrel cannot rotate.

BARREL ROTATION

To rotate a barrel assembly, loosen the patented EZ Lock??? Taper lock nut assembly no more than 1 turn. Rotate barrel to the position of your choice and retighten taper lock nut assembly ??? rmly so that the barrel cannot rotate.

WARNING:

Do not attempt to weld without the barrel being tightly secured in the torch body, or damage to the barrel or body may result.

CONTROLS AND SETTINGS

POTENTIOMETER

The pot is located in the bottom of the pistol grip and provides 3-3/4 turns of rotation and up to 750 ipm.

The pot is mounted to one side of a PC board and is held in place by a support plate; both of which have slots that locate and secure the pot in the handles. The other side of the PC board houses the motor connectors and ribbon cable. Locking disks behind the pot knob provides a stop at the mini- mum and maximum pot settings.

TRIGGER, GAS VALVE AND MICRO SWITCH

The torch trigger is designed so that when it is partially depressed, gas ??? ow starts via the valve located in the torch body, prior to ignition of the arc. When the trigger is partially released after welding (extinguishing the arc), gas ??? ow continues until the trigger is fully released; built-in pre and post gas ??? ow.

The micro switch is wired ???Normally Open??? and secured to the torch block with two (2) screws. An insulator between the torch block and micro switch prevents accidental shorting of the switch leads. The trigger pin reaches through the handle and activates the micro switch just before the trigger bot- toms out on the handle.

Prince XL?? - Owner's Manual - Page 6

DRIVE AND IDLER ROLLS

GENERAL

The Prince?? XL torch comes standard with knurled drive rolls which will handle wire diameters from .023 - 1/16 inch. Optional grooved drive rolls are also available for feeding aluminum wire if desired (see Optional kits).

Drive roll tension is accomplished by means of a pressure adjusting allen screw located on the left hand side of the torch. Proper tension is achieved when wire does not slip if a small amount of pressure is added to the wire as it exits the tip.

----------- IMPORTANT -----------

NOTE: Over-tightening of the drive rolls will cause excessive knurling and/or deformation of the wire. When the complete system is setup properly, feeding wire out of the end of the torch and letting fall on the ground should form a large uniform circle. If it forms a spiral or spring then there is too much tension in the system, please refer to the Cabinet Owners Manual for adjustment to the tension setting.

INCORRECT DRIVE ROLL TENSION IS THE NUMBER ONE

CAUSE OF POOR WIRE FEED PERFORMANCE

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

DRIVE ROLL INSTALLATION AND REMOVAL

Note:

Neither of the handles needs to be removed to access the Drive or Idler Rolls.

1.Using a 5/32??? hex wrench, loosen the Idler Roll tension screw. This will relieve the pressure against the drive roll.

2.Align the Drive Roll Removal Tool (P/N 931-0100) over the ??? ats of the drive roll. Hold the torch with one hand or on a table top, with the other hand give the Removal Tool a quick snap-turn in the CLOCKWISE DIRECTION.

3.Once the drive roll is loose, continue to spin drive roll in the clockwise direction to remove the drive roll from the torch.

4.Install a new drive roll on the left-hand threaded shaft. The drive roll will self-tighten when it is feeding wire.

IDLER ROLL INSTALLATION AND REMOVAL

1.Using a slot type screwdriver, loosen idler screw, taking care not to lose lock washer under idler roll.

2.Insert new idler roll and lock washer onto screw, insuring that idler groove is toward top and lock washer is beneath.

OPTIONAL KITS

Insulated drive roll kits are used to prevent preheating of the wire which may soften it and clog the liner. This picking up of current at the drive rolls rather than at the contact tip is usually not a problem usless using too large of a contact tip or excessively oxidized aluminum wire.

NOTE:

The protective cover is used to help protect the conduit from burns.

PERIODIC MAINTENANCE

Maintenance of the torch will normally consist of a general cleaning of the wire guide system, including tubes, drive rolls, and conduits at regular inter- vals.

Remove spatter build-up from inside of nozzles with a hardwood stick.

The only parts on the Prince?? XL that are subject to normal wear are the conduit, contact tips, gas cups, barrel liners, drive and idler rolls. A supply of these parts should be maintained on hand.

If repairs do become necessary, quali??? ed shop maintenance personnel can easily replace any part.

Your Cobramatic System is designed to provide years of reliable service.

Normal wear and component failure may require occasional service.

The number of units in operation and the importance of minimal ???down time??? will determine to what extent spare parts should be stocked on hand. See the ???Recommended spare parts list??? for the most commonly replaced parts.

Maintenance Tools
