Prince™ XL/Spool Gun - Owner's Manual Page 20
Section 18
Spool Gun Setup
18.1 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 first 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 assembly is designed to automatically control spool drag
and keep the wire from jumping off the spool.
18.2 Disassembly Prince™XL/Spool Gun
Remove trigger pin with punch and remove trigger.
Remove six(6) handle screws and spool adapter if installed.
Remove barrel from gun, loosen barrel taper lock assembly and slide towards
cup. Leave barrel inserted in gun body.
Pull handles apart.
Section 19
MAINTENANCE
Maintenance of the torch will normally consist of a general cleaning of the
wire guide system, including tubes, drive rolls, and conduit at regular inter-
vals. The only parts on the gun that are subject to normal wear are the
conduit, contact tips, gas cups, drive rolls and barrel liners. A supply of those
parts should be maintained on hand.
Proper coolant is a very important part of keeping the water cooled
Prince™XL in good working condition. Any coolant which does not contain
reactive sulfur or chlorine, and which specifically does not react with copper,
brass or aluminum, may be used. One such mixture has proven extremely
successfull when used in conjunction with a water re-circulator. It consists of
the following 3:1 mixture:
Use 3 gallons deionized water (not distilled)
Use 1 gallon ethleyne glycol
Use 1 teaspoon liquid glycerin per gallon of mixture
The coolant flow rate should be 1 quart/minute at 35 p.s.i.
