3. The 208/230 volt 50/60 Hz model POWER MIG is shipped with a 7 ft.(2.1m). input cable and plug connected to the welder. 4. Using the instructions in Figure A.2, have a quali- fied electrician connect a receptacle (Customer Supplied) or cable to the input power lines and the system ground per the U.S. National Electrical Code and any applicable lo[...]

GUN AND CABLE INST ALLA TION The Magnum 250L gun and cable provided with the POWER MIG 215 is factory installed with a liner for .035-.045" (0.9-1.2 mm) electrode and an .035" (0.9 mm) contact tip. Be sure that the contact tip, liner, and drive rolls all match the size of the wire being used. Turn the welder power switch off before instal[...]

B-1 B-1 OPERA TION Read entire Operation section before operating the POWER MIG 215. 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. • Keep your head out of fumes. • Use venti[...]

B-2 B-2 OPERA TION PRODUCT DESCRIPTION The POWER MIG ™ 215 is a complete semiautomatic DC voltage arc welding machine built to meet NEMA specifications. It combines a tapped transformer volt- age power source with a constant speed wire feeder to form a reliable robust performance welding system. A simple control scheme, consisting of continuous f[...]

B-3 B-3 OPERA TION PROCEDURE FOR CHANGING DRIVE AND IDLE ROLL 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.. 3. Remove the outside wire guide retaining plate by loose[...]

B-4 B-4 OPERA TION FEEDING WIRE ELECTRODE When triggering, the electrode and drive mechanism 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 pa[...]

B-5 B-5 OPERA TION 3. Press the trigger to feed the wire electrode through the gun and cable. For solid wire cut the electrode within approximately 3/8" (10 mm) of the end of the contact tip [3/4" (20 mm) for Outershield ® ]. 4. When welding with gas, turn on the gas supply and set the required flow rate (typically 25-35 CFH; 12- 16 lite[...]

B-6 B-6 OPERA TION 9. When no more welding is to be done, close valve on gas cylinder (if used), momentarily operate gun trigger to release gas pressure, and turn off POWER MIG 215. NOTE: When using Innershield electrode, the gas nozzle may be removed from the insulation on the end of the gun and replaced with the gas- less nozzle. This will give i[...]

MAKING A WELD WITH THE SPOOL GUN ADAPTER KIT AND SPOOL GUN INST ALLED In either toggle switch position, closing either gun trigger will cause the electrode of both guns to be electrically “ HOT ” . Be sure unused gun is posi- tioned so electrode or tip will not contact metal case or other metal common to work. ----------------------------------[...]

D-1 D-1 MAINTENANCE • 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. Either a standard .50" (12.7 mm) or optional .62" (15.9 mm) I.D. slip-on gas nozzle may be used and should be selected based on the welding[...]

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" (2.0 mm) Allen wrench. FIGURE D.1 This screw should onl[...]

D-3 D-3 MAINTENANCE GUN HANDLE DISASSEMBL Y The internal parts of the gun handle may be inspected or serviced if necessary.

E-2 E-2 TROUBLESHOOTING PROBLEMS (SYMPTOMS) Major Physical or Electrical Damage is Evident There is no wire feed or open cir- cuit voltage when the gun trigger is pulled. Input power is applied to POWER MIG 215. Output voltage and wire feed is pre- sent when gun trigger is not pulled (not activated). Machine output is low. Welds are “ cold ” , [...]

E-3 E-3 TROUBLESHOOTING PROBLEMS (SYMPTOMS) Poor arc striking with electrode sticking or blasting off. Auxiliary receptacle is “ dead ” - no auxiliary voltage. Rough wire feeding or wire will not feed but drive rolls are turning. POSSIBLE CAUSE 1. Make sure settings for wire feed speed and voltage are correct for process being used. 2. The gas [...]

E-4 E-4 TROUBLESHOOTING PROBLEMS (SYMPTOMS) The wire feed stops while welding. When trigger is released and pulled again the wire feed starts. No control of wire feed speed. Other machine functions are nor- mal. Gas does not flow when gun trigger is pulled. POSSIBLE CAUSE 1. Check the wire feed drive rolls and motor for smooth operation. 2. Check f[...]
