i i SAFETY WARNING CALIFORNIA PROPOSITION 65 WARNINGS Diesel engine exhaust and some of its constituents are known to the State of California to cause cancer, birth defects, and other reproductive harm. The Above For Diesel Engines The engine exhaust from this product contains chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm. The Above For Gasoline Engines ARC WELDING CAN BE HAZARDOUS.
ii ii SAFETY 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. 3.b. Insulate yourself from work and ground using dry insulation. Make certain the insulation is large enough to cover your full area of physical contact with work and ground.
iii iii SAFETY WELDING and CUTTING 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. Avoid welding near hydraulic lines. Have a fire extinguisher readily available. 6.b.

A-2 A-2 INSTALLATION Read this entire installation section before you start installation. SAFETY PRECAUTIONS TILTING Place the machine directly on a secure, level surface or on a recommended undercarriage. The machine may topple over if this procedure is not followed. HIGH FREQUENCY PROTECTION WARNING Locate the Invertec V275-S away from radio controlled machinery. ELECTRIC SHOCK can kill. • Have an electrician install and service this equipment.
A-3 A-3 INSTALLATION INPUT VOLTAGE RECONNECT PROCEDURE When received directly from the factory, units are connected for, 460 VAC. If 460 VAC is the desired input, then the machine may be connected to the power system without any setup required inside the reconnect door. For other voltages refer to the instructions located on the Reconnect Panel Access Door or follow the instructions below. CAUTION Failure to follow these instructions can cause immediate failure of components within the welder.
A-4 A-4 INSTALLATION OUTPUT CONNECTIONS QUICK DISCONNECT PLUGS Refer to figure A.2 for the location of the 6-Pin Remote Receptacle and the Output Terminals. FIGURE A.2 OUTPUT CONNECTIONS A quick disconnect system is used for the welding cable connections. The welding plug included with the machine is designed to accept a welding cable size of 1/0 to 2/0. 6-PIN REMOTE RECEPTACLE 1. Remove 1 in. (25mm) of welding cable insulation. REMOTE ON 2. Slide rubber boot onto cable end.
B-1 OPERATION Read and understand this entire section before operating your machine. B-1 GENERAL DESCRIPTION The Invertec V275-S is a 275 amp arc welding power source that utilizes single or three phase input power, to produce constant current output. The welding response of this Invertec has been optimized for stick (SMAW) and TIG (GTAW). SAFETY PRECAUTIONS WARNING ELECTRIC SHOCK can kill. OPERATIONAL FEATURES • Do not touch electrically live parts such as output terminals or internal wiring.
B-2 B-2 OPERATION CONTROLS AND SETTINGS All operator controls and adjustments are located on the case front of the V275-S. Refer to Figure B.1 and corresponding explanations. FIGURE B.1 — CASE FRONT CONTROLS. 2 8 3 LOCAL REMOTE 4 CC STICK TIG 10 OUTPUT ARC FORCE -10 HOT START ON 5 OFF +10 6 9 REMOTE ON 1 OFF 7 1. POWER SWITCH - Place the lever in the “ON” position to energize the machine.
B-3 OPERATION 6. ARC FORCE - This control functions in CC Stick SMAW modes to adjust the Arc Force. The arc is soft at the minimum settings and more forceful or driving at the maximum settings. Higher spatter levels may be present at the maximum settings. Full range is from -10(Soft) to +10(Crisp) 7. OUTPUT TERMINALS - These quick disconnect terminals provide connection points for the electrode and work cables. Refer to Output Connection in the Installation chapter for proper cable sizes.
C-1 ACCESSORIES C-1 OPTIONS / ACCESSORIES TIG OPTIONS REMOTE OUTPUT CONTROL - Consists of a control box with choice of two cable lengths. Permits remote adjustment of output, 6 pin connection. Order K857 for 25 ft. (7.6m) or K857-1 for 100 ft. (30.5m) Hand Amptrol - may be used in place of the Foot Amptrol. Fastens to the torch for convenient thumb control. Comes with a 25 ft. (7.6m) cable. Order K963-1 (for smaller handle 9, 17 or 20 series torches.
D-1 D-1 MAINTENANCE WARNING ELECTRIC SHOCK can kill. • Have an electrician install and service this equipment. • Turn the input power off at the fuse box before working on equipment. • Do not touch electrically hot parts. • Prior to Performing preventative maintenance, perform the following capacitor discharge procedure to avoid electric shock. --------------------------------------------------------------------- 4. Obtain a high resistance and high wattage resistor (25-1000 ohms and 25 watts minimum).
D-2 MAINTENANCE ROUTINE MAINTENANCE 1. Perform the following preventive maintenance procedures at least once every six months. It is good practice to keep a preventive maintenance record; a record tag attached to the machine works best. 2. Remove the machine wrap-around cover and perform the input filter capacitor discharge procedure (detail at the beginning of this chapter). 3. Keeping the machine clean will result in cooler operation and higher reliability.

E-2 TROUBLESHOOTING & REPAIR PC BOARD TROUBLESHOOTING PROCEDURES WARNING ELECTRIC SHOCK can kill. Have an electrician install and service this equipment. Turn the input power OFF at the fuse box before working on equipment. Do not touch electrically hot parts. _______________________________ CAUTION: Sometimes machine failures appear to be due to PC board failures. These problems can sometimes be traced to poor electrical connections.
E-3 E-3 TROUBLESHOOTING Observe all Safety Guidelines detailed throughout this manual PROBLEMS (SYMPTOMS) POSSIBLE CAUSE RECOMMENDED COURSE OF ACTION OUTPUT PROBLEMS Major physical or electrical damage is observed when cover wrap-around is removed. The machine is dead - no output. 1. The input power switch must be in the ON position. 2. Make sure the input voltage is correct for the machine. 3.
E-4 E-4 TROUBLESHOOTING Observe all Safety Guidelines detailed throughout this manual PROBLEMS (SYMPTOMS) POSSIBLE CAUSE RECOMMENDED COURSE OF ACTION OUTPUT PROBLEMS Output turns on momentarily, then switches off and repeats cycle. 1. Check the input voltages and reconnection procedures. Make sure the input voltage is correct for the machine. See Input Voltage Reconnect Procedure. 2. Check or replace remote control device. (If used) Remote output control not functioning.
E-5 E-5 TROUBLESHOOTING Observe all Safety Guidelines detailed throughout this manual PROBLEMS (SYMPTOMS) POSSIBLE CAUSE RECOMMENDED COURSE OF ACTION OUTPUT PROBLEMS No output - Main input fuses open, indicating excessive current draw. 1. Inspect input leads for possible shorts or grounds or mis-connections. 2. Install new fuses and reapply power. If fuses open again, consult a Lincoln Authorized Field Service Facility. The machine operates normally when connected for 200 - 230VAC input.
E-6 E-6 TROUBLESHOOTING Observe all Safety Guidelines detailed throughout this manual PROBLEMS (SYMPTOMS) POSSIBLE CAUSE RECOMMENDED COURSE OF ACTION OUTPUT PROBLEMS The machine will not produce more than 200 amps. 1. This may be normal operation. If the output current exceeds 300 amps, an electronic protection circuit will reduce the current to less than 200 amps. The machine will continue to produce this low current until the If all recommended possible areas of protection circuit is reset.
E-7 E-7 TROUBLESHOOTING Observe all Safety Guidelines detailed throughout this manual PROBLEMS (SYMPTOMS) POSSIBLE CAUSE RECOMMENDED COURSE OF ACTION WELDING PROBLEMS Poor welding, weld settings drift, or output power is low. 1. Make sure the machine settings are correct for the weld process being used. 2. Check machine performance on LOCAL control. If OK then the remote control device may be faulty. Check or replace. 3. Check the input voltages and input voltage reconnect procedures.
