RED-D-ARC PM 255 Red-D-Ar c Spec-Built W elding Equipment This RED-D-ARC welder is built to RED-D-ARC Extreme Duty design specifications by Lincoln Electric. Safety Depends on Y ou This welder is designed and built with safety in mind. However, your overall safety can be increased by proper installation .
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.
ii SAFETY ii ARC RA YS can b urn. 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 U.S. National Electrical Code, all local codes and the manufacturer’s recommendations.

A-3 A-3 INST ALLA TION 4. Using the instructions in Figure A.3, have a quali- fied electrician connect the receptacle or cable to the input power lines and the system ground per the U.S. National Electrical Code and any applica- ble local codes. See “Technical Specifications” at the beginning of this chapter for proper wire sizes.

SEE THE UNITED STATES NATIONAL ELECTRICAL CODE AND/OR LOCAL CODES FOR OTHER DETAILS AND MEANS FOR PROPER GROUND- ING. CONNECT TO HOT WIRES OF A THREE- WIRE, SINGLE PHASE SYSTEM OR TO ONE PHASE OF A TWO OR THREE PHASE SYSTEM.
GUN AND CABLE INST ALLA TION The Magnum 250L gun and cable provided with the PM 255 is factory installed with a liner for .035-.045" (0.9-1.2 mm) electrode and an .035" (0.9 mm) contact tip. Install the .045 tip (also provided) if this wire size is being used.
B-1 B-1 OPERA TION Read entire Operation section before operating the PM 255. 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.
B-2 B-2 OPERA TION PR ODUCT DESCRIPTION The PM 255 is a complete semiautomatic constant voltage DC arc welding machine built to meet NEMA specifications. It combines a constant voltage power source and a constant speed wire feeder with a micro- computer-based controller to form a reliable high-per- formance welding system.
B-3 B-3 OPERA TION PR OCEDURE FOR CHANGING DRIVE AND IDLE R OLL SETS 1. Turn off the power source. 2. Release the pressure on the idle roll by swinging the adjustable pressure arm down toward the back of the machine. Lift the cast idle roll assembly and allow it to sit in an upright position.
B-4 B-4 OPERA TION FEEDING WIRE ELECTR ODE When triggering, the electrode and drive mecha- nism are electrically “hot” relative to work and ground and remain “hot” several seconds after the gun trigger is released. NOTE: Check that drive rolls, guide plates and gun parts are proper for the wire size and type being used.
B-5 B-5 OPERA TION It is not necessary to repeat either of the above proce- dures each time the unit is powered up. The unit will remember the run-in mode from the previous power down and return you to that same state upon your next power up. Thus, you need only perform one of the above procedures when you want to change the run-in mode.
B-6 B-6 OPERA TION F AN CONTR OL The fan is designed to come on automatically when a weld arc is established. The fan will stay on for a mini- mum of 6 minutes after the weld arc is terminated. The fan will also stay on when the machine ’ s welding and feeding are disabled during thermostatic over temperature protection.
C-1 C-1 A CCESSORIES DRIVE R OLL KITS Refer to Table C.1 for various drive roll kits that are available for the PM 255. All items in Bold are sup- plied standard with the POWER MIG. TABLE C.1 3/64" (1.2 mm) ALUMINUM FEEDING KIT (K1703-1) This kit helps push feeding aluminum through stan- dard machine feeder and gun.
C-2 C-2 A CCESSORIES 4. Attach the rectangular 10-pin plug connector on the timer kit wiring harness to the mating receptacle connector located directly behind the removed cover panel. Be sure that the latch on the connec- tor is aligned with the one on the board and insert it until the latch engages.
C-3 C-3 A CCESSORIES SPOOL GUN AD APTER KIT (K1700-1) (Inc luded in the K1692-1) Remove all input power to the PM 255 before pro- ceeding. The Spool Gun Adapter Kit provides direct connection and use of the K1692-1 Spool Gun (with remote speed control) with the PM 255 wire feed welder.
D-1 D-1 MAINTENANCE 3 . If using optional adjustable slip-on nozzles, see Table D.2 in this section. • Be sure the nozzle insulator is fully screwed onto the gun tube and does not block the gas holes in the diffuser. • Slip the appropriate gas nozzle onto the nozzle insulator.
Counterclockwise ➣ D-2 D-2 MAINTENANCE 7. Screw the gas diffuser onto the end of the gun tube and securely tighten. Be sure the gas diffuser is correct for the liner being used. (See table and dif- fuser stencil.) 8. Tighten the set screw in the side of the gas diffuser against the cable liner using a 5/64" (2.

E-2 E-2 TR OUBLESHOO TING PROBLEMS (SYMPT OMS) Major Physical or Electrical Damage is Evident There is no wire feed or open cir- cuit voltage when the gun trigger is pulled. The machine displays are lit indicating input power to the PM 255. Output voltage and wire feed is pre- sent when gun trigger is not pulled (not activated).
E-3 E-3 TR OUBLESHOO TING PROBLEMS (SYMPT OMS) Poor arc striking with electrode sticking or blasting off. POSSIBLE AREAS OF MISADJUSTMENT(S) 1. Make sure settings for wire feed speed and voltage are correct for process being used. 2. The Run-In (Fast or Slow) speed may be wrong for process and technique being used.
E-4 E-4 TR OUBLESHOO TING PROBLEMS (SYMPT OMS) Gas does not flow when gun trigger is pulled. POSSIBLE AREAS OF MISADJUSTMENT(S) 1. Make sure gas supply is con- nected properly and turned “ on ” . 2. If the gas solenoid does actuate (click) when the gun trigger is pulled there may be a restriction in the gas supply line.
