B-2 B-2 OPERA TION POWER MIG 300 PRODUCT DESCRIPTION The POWER MIG 300 is a complete semiautomatic multi-process DC arc welding machine offering CV and CC DC welding.
5. MULTI-PROCESS PANEL - This panel enables selection of weld modes as well as adjustment of certain weld parameters within each weld mode. The eight discrete LED ’ s are used to identify which selec- tion will be shown on the display.
B-4 B-4 OPERA TION POWER MIG 300 SETTING AND CONFIGURING THE POWER MIG 300 FOR WELDING • Check that the electrode polarity is correct for the process and turn the Power Switch to the "ON" position.
B-5 B-5 OPERA TION POWER MIG 300 MUL TI-PROCESS P ANEL FUNCTIONS Weld Mode Setting the Weld Mode is selecting the proper program from the ones available in the machine ’ s memory for a particular welding application. The table on the right side of the front panel (See Figure B.
B-6 B-6 OPERA TION POWER MIG 300 Arc Control (See Table B.2) There are no specific unit values offered because the setting of this feature largely depends upon operator preference. Arc Control has a different effect on the character of the arc depending upon the welding process applied.
B-7 B-7 OPERA TION POWER MIG 300 In the case of special waveforms designed for pulsed weld- ing aluminum, Pulse on Pulse ™ , the effect is similar to what occurs with standard pulse. As the Arc Control is increased from +1 to +10 the frequency of the Pulse on Pulse array increases.
B-8 B-8 OPERA TION POWER MIG 300 5. Rotate the spindle and adapter so the retaining spring is at the 12 o'clock position. 6. Position the Readi-Reel so that it will rotate in a direc- tion when feeding so as to be de-reeled from top the of the coil.
B-9 B-9 OPERA TION POWER MIG 300 4. Re-install the Retaining Collar. Make sure that the Release Bar “ pops up ” and that the collar retainers fully engage the retaining ring groove on the spin- dle.
B-10 B-10 OPERA TION POWER MIG 300 SPECIAL WELDING PROCESSES A V AILABLE ON THE POWER MIG 300 PULSE WELDING (GMA W-P) The pulsed-arc process is, by definition, a spray trans- fer process wherein spray transfer occurs in pulses at regularly spaced intervals.
B-1 1 B-1 1 OPERA TION POWER MIG 300 PULSE-ON-PULSE ™ (GMA W-PP) Pulse on Pulse ™ is a Lincoln process specifically designed for use in welding relatively thin (less than 1/4" thick) aluminum (See Table B.3). It gives weld beads with very consistent uniform ripple.
B-12 B-12 OPERA TION POWER MIG 300 POWER MODE ™ The Power Mode ™ process was developed by Lincoln to maintain a stable and smooth arc at low procedure settings which are needed to weld thin metal without pop-outs or burning-through. For Aluminum welding, it provides excellent control and the ability to maintain constant arc length.
C-1 C-1 ACCESSORIES DRIVE ROLL KITS Refer to Table C.1 for various drive roll kits that are available for the POWER MIG. All items in Bold are supplied standard with the POWER MIG. TABLE C.1 * .035 Aluminum recommended for Push-Pull systems only. 3/64" (1.

D-1 D-1 MAINTENANCE CONT ACT TIP AND GAS NOZZLE INST ALLA TION a. Choose the correct size contact tip for the elec- trode being used (wire size is stenciled on the side of the contact tip) and screw it snugly into the gas diffuser. b. Be sure the nozzle insulator is fully screwed onto the gun tube and does not block the gas holes in the diffuser.
D-2 D-2 MAINTENANCE 5. Seat Liner bushing into back of gun. Secure Liner by tightening set screw. Do not install the gas dif- fuser at this time. 6 . Lay the cable straight and trim Liner to 9/16 ” . Remove burrs. 7. Secure the gas diffuser into the tube.
