Handymig 170i OPERA TOR’S MANUAL IM711 January, 2001 Safety Depends on You LiquidArc machines are designed and built with safety in mind. However, your overall safety can be increased by proper installation ... and thoughtful operation on your part.
FOR ENGINE powered equipment. 1.a. Turn the engine off before troubleshooting and maintenance work unless the maintenance work requires it to be running. ____________________________________________________ 1.b. Operate engines in open, well-ventilated areas or vent the engine exhaust fumes outdoors.
SAFETY 2.i.4 Connect the work cable to the work piece as close as possible to the area being welded. (This is also a good practice to eliminate a common problem on welding - a poor work connection. 2.i.5 Do not work next to the welding power source. ADDITIONAL PRECAUTIONS FOR WELDERS WITH PACEMAKERS 2.
iii SAFETY iii ARC RA YS can burn. 4.a. Use a shield with the proper filter and cover plates to protect your eyes from sparks and the rays of the arc when welding or observing open arc welding. Headshield and filter lens should conform to ANSI Z87. I standards.
FOR ELECTRICALL Y powered equipment. 8.a. Turn off input power using the disconnect switch at the fuse box before working on the equipment. 8.b. Install equipment in accordance with the National Electrical Code, all local codes and the manufacturer ’ s recommendations.
SAFETY v v INSTR UCTIONS FOR ELECTRO- MA GNETIC COMP A TIBILITY Conformance Products displaying the C-Tick mark are in conformity with Australian/New Zealand requirements for Electromagnetic Compatibility (EMC) according to standard (emission) AS/NZS 3652 "Electromagnetic Compatibility – Arc Welding Equipment".
Thank You for selecting a QUALITY product. We want you to take pride in operating this LiquidArc product ••• as much pride as we have in bringing this product to you! Read this Operators Manual completely before attempting to use this equipment.

A-2 INST ALLA TION SAFETY PRECA UTIONS • Read entire installation section before starting installation. IDENTIFY AND LOCA TE COMPONENTS If you have not already done so, unpack the Handymig 170i from its carton and remove all packing material around the Handymig 170i.
A-3 INST ALLA TION SELECT SUIT ABLE LOCA TION 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-4 A-4 INST ALLA TION W ork Cable Installation Refer to Figure A.2. 1. Open the wire feed section door on the right side of the Handymig 170i. 2. Pass the end of the work cable that has the termi- nal lug with the smaller hole through the Work Cable Access Hole (1) in the case front.
A-5 INST ALLA TION BE SURE TO KEEP YOUR FACE AWAY FROM THE VALVE OUTLET WHEN “ CRACKING ” THE VALVE. Never stand directly in front of or behind the flow regulator when opening the cylinder valve. Always stand to one side. 3. Attach the flow regulator to the cylinder valve and tighten the union nut securely with a wrench.
A-6 INST ALLA TION ELECTRICAL INPUT CONNECTION FOR RA TED OUTPUT ELECTRIC SHOCK can kill. • Disconnect input power by removing plug from receptacle before working inside Handymig 170i. • Use only grounded receptacle. • Do not touch electrically “ hot ” parts inside Handymig 170i.
B-1 OPERA TION SAFETY PRECA UTIONS 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 dangerous.
B-2 B-2 OPERA TION WELDING CAP ABILITY The Handymig 170i is rated at 130 amps, 20 volts, at 20% duty cycle on a ten minute basis. It is capable of higher output currents at lower duty cycles. . LIMIT A TIONS Arc Gouging cannot be performed with the Handymig 170i.
B-3 OPERA TION WELDING OPERA TIONS SEQUENCE OF OPERA TION Wire Loading Refer to Figure B.2 and B.3. The machine power switch should be turned to the OFF ( “ O ” ) position before working inside the wire feed enclosure. The machine is shipped from the factory ready to feed 8 ” (200 mm) diameter spools [2.
B-4 B-4 OPERA TION Wire Threading Refer to Figure B.4 1 . Release the Spring Loaded Pressure Arm (1) rotate the Idle Roll Arm (2) away from the Wire Feed Drive Roll (3). Ensure that the groove size in the feeding position on the drive roll matches the wire size being used.
B-5 B-5 OPERA TION Making A Weld 1. See “ Process Guidelines ” in this section for selec- tion of welding wire and shielding gas and for range of metal thicknesses that can be welded. 2. See the Application chart on the inside of the wire feed compartment door for information on setting the Handymig 170i controls.
B-6 B-6 OPERA TION The Handymig 170i is suitable for .035"(0.9mm) alu- minum wire and .023" – .035"(0.6-0.9mm) stainless wire. Refer to Table B.
Fumes and slag generated from Innershield type electrodes recom- mended for use with this welding machine can be toxic. • Avoid contact with eyes and skin. • Do not take internally. • Keep out of reach of children. • Follow all safety precautions found in this operating manual.
B-8 B-8 LEARNING T O WELD THE SELF-SHIELDED FCA W WELDING ARC Figure B.9 illustrates the action taking place in the self shielded FCAW (Innershield) welding arc. It closely resembles what is actually seen while welding. FIGURE B.9 The “ arc stream ” is seen in the middle of the picture.
B-9 B-9 LEARNING T O WELD PROCESS SELECTION By gaining knowledge of the differences between the two processes, you will be able to select the best process for the job you have at hand. In selecting a process, you should consider: For GMAW (MIG) Process 1.
B-10 B-10 LEARNING T O WELD 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.
B-11 B-11 LEARNING T O WELD 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. Vertical-down welds may be applied to 5/32 ” (3.
B-12 B-12 LEARNING T O WELD 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. • The Correct Way To Strike An Arc • Be sure the work clamp makes good electrical contact to the work.

B-14 B-14 LEARNING T O WELD MA CHINE SET UP FOR THE GMA W (MIG) PROCESS • 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. • See the Application Guide on the inside of wire feed section door for information on setting the controls.
Helpful Hints • 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.
B-16 B-16 LEARNING T O WELD • After you strike the arc, practice the correct electri- cal stickout. Learn to distinguish it by its sound. • When you are sure that you can hold the correct electrical stickout, with a smooth “ crackling ” arc, start moving.
B-17 B-17 LEARNING T O WELD Proper Gun Handling Most feeding problems are caused by improper han- dling of the gun cable or electrodes. • Do not kink or pull the gun around sharp corners • Keep the gun cable as straight as practical when welding. • Do not allow dolly wheels or trucks to run over the cables.
