K499 Argon-Mixed Gas Regulator and Hose Kit

Install the pressure-flow regulator and gauge to a cylinder according to the instructions in Section 1.10. Connect one end of the 10 foot (3.0 m) hose to the SP-100 gas inlet fitting and the other end to the regu- lator fitting.

The K499 argon-mixed gas pressure-flow regulator is preset by the manufacturer to deliver a nominal flow of 30 cubic feet per hour (14 1/min) of argon or argon- mixed gas. This setting cannot be changed.

.035" (0.9 mm) Innershield Welding Kit

Includes a contact tip, gasless nozzle, and a cable liner to permit the SP-100 gun and cable to use .035 (0.9 mm) diameter flux-cored electrode. Also included is a spool of .035 (0.9 mm) Innershield® NR-211-MP.

The K549-1 Kit is for use with the Magnum™ 100L gun (with red trigger). The fitting on the end of the liner is stenciled with the maximum rated wire size (.045"/1.2 mm).

The K464 Kit is for use with the earlier “Lincoln Electric®” gun (with black trigger). The end of the brass fitting on the end of the liner for .035 (0.9 mm) wire is color coded green. The .023-.030 (0.6-0.8 mm) factory installed liner is color coded orange.

See Maintenance and Troubleshooting Section for instructions on installing liner and contact tip in gun.

K467 Input Line Cord

Same as line cord supplied with the SP-100 but has a NEMA type 5-20P plug for use on a 25 amp branch circuit with a nominal voltage rating of 115 volts to 125 volts, 60 hertz. Install per the following:

1.Turn the SP-100 Power Switch to OFF (“O”).

2.If connected, remove the line cord plug from power supply receptacle.

3.Remove the two screws that hold the line cord receptacle in the SP-100 flanged inlet connector and disconnect the line cord from the SP-100.

4.Connect the S18410 input line cord receptacle to the SP-100 and replace the retaining screws.

OPERATING INSTRUCTIONS

WARNING

ELECTRIC SHOCK can kill.

• Do not touch electrically live parts or electrode with skin or wet clothing.

•Insulate yourself from work and ground.

•Always wear dry insulating gloves.

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

FUMES AND GASES can be danger-

ous.

• Keep your head out of fumes.

• Use ventilation or exhaust to remove

fumes from breathing zone.

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

WELDING SPARKS can cause fire or explosion.

•Keep flammable material away.

•Do not weld on closed containers.

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

ARC RAYS can burn eyes and skin.

•Wear eye, ear and body protection.

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

See additional warning information at front of this owners manual.

DUTY CYCLE

The SP-100 is rated at the following duty cycles.

	Duty
Condition	Cycle(1)	Amps	Volts
Rated Output	20%	90	18
Maximum	30%	100	17
Output(2)
CSA Rated Output	20%	63	20

(1)Based upon 10 minute time period. (i.e. for 20% duty cycle it is 2 minutes on and 8 minutes off.)

(2)Using Optional K467 Input line cord on a 25 amp branch circuit.

SELECTING A WIRE SPOOL SIZE

Select a spool size so that the wire is used up within a six month period. This eliminates needless waste of wire due to oxidation and rusting. Dirty, oxidized, or rusty wire results in poor wire feeding and poor weld- ing performance. This wire should be discarded.

FEEDING WELDING WIRE

WARNING

When inching the welding wire, the drive rolls, the gun connector block and the gun contact tip are always energized relative to work and ground and remain energized several seconds after the gun trigger is released.

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

1.Remove gas nozzle and contact tip from end of gun according to instructions in the maintenance sec- tion of this manual.

2.Turn the SP-100 ON (“I”).

3.Straighten the gun cable assembly.
