Page 3: Electric Shock Can Kill
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. - Page 4 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.

Page 20: Learning To Weld
LEARNING TO WELD 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 weld- ing and develop this skill. For more detailed informa- tion, order a copy of “New Lessons in Arc Welding” listed at the end of this manual. - Page 21 The “arc stream” is seen in the middle of the picture. This is the electric arc created by the electric current flowing through the space between the end of the wire electrode and the base metal. The temperature of this arc is about 6000°F, which is more than enough to melt metal.
- Page 22 2. Can I afford the extra expense, space, and lack of portability required for gas cylinders and gas sup- ply? 3. Do I require clean, finished-looking welds? If you have answered yes to all the above questions GMAW may be the process for you. If you have answered no to any of the above questions, then you should consider using the FCAW process.
- Page 23 B-10 FIGURE B.12 Penetration Unless a weld penetrates close to 100% of the metal thickness, a butt weld will be weaker than the material welded together. In the example shown in Figure B.13, the total weld is only half the thickness of the material thus the weld is only approximately half as strong as the metal.
- Page 24 B-11 PROPER GUN ANGLE PROPER GUN ANGLE FOR GMAW PROCESS FOR FCAW PROCESS WELDING IN THE VERTICAL UP POSITION WELDING IN THE VERTICAL UP POSITION FIGURE B.16 Vertical-down Welding Refer to Figure B.17 Vertical-down welds are applied at a fast pace. These welds are therefore shallow and narrow and, as such, are excellent for sheet metal.
- Page 25 B-12 FIGURE B.18 WARNING ARC RAYS can burn eyes and skin. When using an open arc process, it Is necessary to use correct eye, head and body protection. Protect yourself and others, read “ARC RAYS can burn” at the front of this manual.
- Page 26 B-13 Helpful Hints 1. For general welding, it is not necessary to weave the arc, neither forward or backward nor sideways. Weld along at a steady pace. You will find it easier. 2. When welding on thin plate, you will find that you will have to increase the welding speed, whereas when welding on heavy plate, it is necessary to go more slowly in order to get good penetration.
- Page 27 B-14 MACHINE SET UP FOR THE GMAW (MIG) PROCESS 1. See PROCESS GUIDELINES in the OPERATION section for selection of welding wire and shielding gas, and for range of metal thicknesses that can be welded. 2. See the Application Guide on the inside of wire feed section door for information on setting the controls.
- Page 28 B-15 Contact Tip Wire Electrode FIGURE B.24 3. The Correct Electrical Stickout (ESO) The electrical stickout (ESO) is the distance from the end of the contact tip to the end of the wire. See Figure B.24. Once the arc has been established, maintaining the correct ESO becomes extremely important.

Page 29: Troubleshooting Welds
B-16 4. After you strike the arc, practice the correct electri- cal stickout. Learn to distinguish it by its sound. 5. When you are sure that you can hold the correct electrical stickout, with a smooth “crackling” arc, start moving. Look at the molten puddle constantly, 6. - Page 30 B-17 Proper Gun Handling Most feeding problems are caused by improper han- dling of the gun cable or electrodes. 1. Do not kink or pull the gun around sharp corners 2. Keep the gun cable as straight as practical when welding.

INNERSHIELD (FCAW) CONVERSION Several changes are needed to convert the unit for operation with the Innershield (FCAW) process. The following conversions should be reviewed before welding with (FCAW): 1. Change the output polarity to DC(–). See “Work Cable Installation” in Installation section for details. 2. -
Page 34: Maintenance
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. -

SP 170-Iº Components shipped with UWW-170• º If other size wire feeding is desired use the additional Contact Tips shipped loose with your SP 170-I. • 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. -

Make certain the set screw is located on the flat portion of the shaft and tighten. CHANGING DRIVE ROLL (UWW-170 only) The UWW-170 has dual knurled grooves of the same size; either capable of feeding .035/.045 (0.9/1.2mm) wire. When a groove becomes worn, use the above procedure to flip the roll to the unused groove. -
