DESCRIPTION OF CONTROLS Become familiar with the SP-100 controls and compo- nents before attempting to weld. Refer to illustrations and lettered items below for brief descriptions. A. Wire speed — Controls the wire speed from 50 – 400 in./min (1.3 – 10 m/min). The control can be preset on the dial to the setting specified on the SP-100 Applic[...]

Work Cable Installation 1. Open the wire feed section door on the right side of the SP-100. 2. Pass the end of the work cable that has the termi- nal lug with the smaller hole through the hole (hole D) next to the louvers in the case front. 3. Route the cable under and around the back of the wire feed unit. 4. Using wing nut provided, connect the t[...]

ELECTRICAL INPUT CONNECTION Code Requirements This welding machine must be connected to power source in accordance with applicable electrical codes. The United States National Electrical Code (Article 630-B, 1990 Edition) provides standards for amper- age handling capability of supply conductors based on duty cycle of the welding power source. If t[...]

Extension Cord If an extension cord is required, use one that is rated for the application and is 3 conductor #14 AWG (2.1 mm 2 ) or larger. The recommended maximum lengths are 25 ft (7.5 m) if #14 AWG (2.1 mm 2 ) is used and 50 ft (15 m) if #12 AWG* (3.3 mm 2 ) is used. *AMERICAN WIRE GAUGE SHIELDING GAS When using the GMAW process, a cylinder of [...]

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[...]

– 14 – 4. Depress the gun trigger switch and feed welding wire through the gun and cable (Point gun away from yourself and others while feeding wire.) Release gun trigger after wire appears at end of gun. 5. Replace contact tip and gas nozzle. 6. Cut the wire off 1/4 – 3/8" (6 – 10 mm) from the end of the tip. The SP-100 is now ready t[...]

No one can learn to weld simply by reading about it. Skill comes only with practice. The following pages will help the inexperienced operator to understand welding and develop this skill. For more detailed infor- mation, order a copy of “New Lessons in Arc Welding” listed inside the back cover of this manual. THE ARC-WELDING CIRCUIT The operato[...]

– 16 – The cored wire melts in the arc and tiny droplets of molten metal shoot across the arc into the molten pool. The wire sheath provides additional filler metal for the joint to fill the groove or gap between the two pieces of the base metal. The core materials also melt or burn in the arc and perform several functions. They make the arc st[...]

– 17 – Practice. The best way of getting practice in the four skills that enable you to maintain: 1. Correct welding position 2. Correct way to strike an arc 3. Correct electrical stickout 4. Correct welding speed is to spend a little more time on the following exercise. Use the following: Mild Steel 16 gauge or 1/16 inch (1.6 mm) Electrode .03[...]

– 18 – steel can usually be easily welded without special pre- cautions. Some steels, however, contain higher car- bon levels or other alloys and are more difficult to weld. Basically, if a magnet sticks to the metal and if you can easily cut the metal with a file, chances are good that you will be able to weld the material with the SP-100. For[...]

– 19 – Vertical-Up and Overhead Welding The problem, when welding vertical-up, is to put the molten metal where it is wanted and make it stay there. If too much molten metal is deposited, gravity will pull it downwards and make it “drip.” Therefore, a certain technique has to be followed. When welding out-of-position, run stringer beads. Do[...]

MACHINE SETUP FOR THE GMA W (MIG) PROCESS 1. See “Recommended Processes and Equipment” for selection of welding wire and shielding gas and for range of metal thicknesses that can be welded. 2. See the “Welding ” chart on the inside of wire feed section door or in this manual for information on setting the controls. 3. Set the “Voltage” [...]

– 21 – TROUBLESHOOTING WELDS Good welds have excellent appearance. To Eliminate Porosity (in order of importance) — Turn on gas supply, if used 1. Decrease voltage 2. Increase stickout 3. Increase WFS (wire feed speed) 4. Decrease drag angle 5. Decrease travel speed. NOTE: Always be sure the joint is free from mois- ture, oil, rust, paint or [...]

ROUTINE MAINTENANCE Requires NO Maintenance • Drive Motor and Gearbox - Lifetime lubrication • Fan Motor - Lifetime lubrication. • Wire Reel Spindle - Do NOT lubricate shaft. Before Each Use • Check over machine and accessories for any obvious condition that may prevent safe performance or operation, repair or replace items as necessary to [...]

– 23 – • Replace Liner - when wire feeding problems occur and other items have been checked. NOTICE: The variation in cable lengths prevents the interchangeability of liners. Once a liner has been cut for a particular gun, it should not be installed in another gun unless it can meet the liner cutoff length requirement. Remove gun and cable as[...]
