351040, Miami, Florida 33135 or CSA Standard W117.2-1974. A Free copy of “Arc Welding Safety” booklet E205 is available from the Lincoln Electric Company, 22801 St. Clair Avenue, Cleveland, Ohio 44117-1199. BE SURE THAT ALL INSTALLATION, OPERATION, MAINTENANCE AND REPAIR PROCEDURES ARE PERFORMED ONLY BY QUALIFIED INDIVIDUALS.
ELECTRIC SHOCK can kill. 3.a. The electrode and work (or ground) circuits are electrically “hot” when the welder is on. Do not touch these “hot” parts with your bare skin or wet clothing. Wear dry, hole-free gloves to insulate hands.

WELDING SPARKS can cause fire or explosion. 6.a. Remove fire hazards from the welding area. If this is not possible, cover them to prevent the welding sparks from starting a fire. Remember that welding sparks and hot materials from welding can easily go through small cracks and openings to adjacent areas.

• Machine must be plugged into a receptacle which is grounded per any national, local or other applicable electrical codes. • The SP-175T power switch is to be in the OFF (“O”) position when installing work cable and gun and when connecting power cord to input power.
SELECT SUITABLE LOCATION Locate the welder in a dry location where there is free circulation of clean air into the louvers in the back and out the front of the unit. A location that minimizes the amount of smoke and dirt drawn into the rear louvers reduces the chance of dirt accumulation that can block air passages and cause overheating.
(4). FIGURE A.4 GUN INSTALLATION As shipped from the factory, the SP-175T gun is ready to feed .023" – .025" solid wire. If .030"-.035” (0.8 - .09mm) solid wire is to be used, change the contact tip to the appropriate size. If .035” Flux-cored wire is to be...

AWG Size Lag) 230 Volt Input Connection The SP-175T is shipped from the factory connected for 230 volt input power. If the welder has been recon- nected for 208 volt input power and 230 volt input is desired, perform the following reconnection instruc- tions: 1.
The machine is rugged and reliable and has designed for dependable service and long life. RECOMMENDED PROCESSES The SP-175T can be used for welding mild steel using the GMAW, single pass, process which requires a supply of shielding gas or it can be used for the self-...
4 in. (100 mm) diameter spools of wire. WELDING CAPABILITY The SP-175T is rated at 130 amps, 20 volts, at 30% duty cycle on a ten minute basis. It is capable of high- er output currents at lower duty cycles. .
Also make certain the start end of the wire, which may pro- trude through the side of the spool does not contact any metallic case parts. Wire Spindle Shaft SP-175T FIGURE B.2 8” Wire Spool To Wire Drive FIGURE B.3 4"...
11. Turn the SP-175T OFF (“O”). 12. Replace contact tip and gas nozzle. 13. Refer to Figure B-6. Cut the wire off 3/8” – 1/2” (10 – 13 mm) from the end of the tip. The SP-175T is SP-175T now ready to weld.
PROCESS GUIDELINES The SP-175T can be used for welding mild steel using the GMAW, single pass, process which requires a supply of shielding gas or it can be used for the self- ®...
The circuit breaker must be manually reset. Thermal Protection The SP-175T has a rated output duty cycle of 30%. If the duty cycle is exceeded, a thermal protector will shut off the output until the machine cools to a reason- able operating temperature.
Handle height is easily adjustable. Bottom tray provided for tools and accessories. Easy assembly required; takes less than 15 minutes. 6. K586-1 Deluxe Adjustable Gas Regulator & ® Hose Kit Accommodates CO ® SP-175T or mixed Gas Cylinders.
POWER SOURCE COMPARTMENT In extremely dusty locations, dirt may clog the air passages causing the welder to run hot. Blow dirt out of the welder with low pressure air at regular intervals to eliminate excessive dirt and dust build-up on interval parts.
Aluminum or Stainless Kit* • If .030 (0.8mm) Solid wire feeding is desired use the KP2039-2B1 Contact Tip shipped loose with your SP-175T. * It is important when changing between welding with steel wire and aluminum to exchange feeding components due to the lubricant applied to steel wire. Failure to do so may result in contaminated welds when welding aluminum.
