OPERATION WIRE FEED WIRE WELD MODE VOLTMETER CIRCUIT BREAKER SPEED SELECTOR (OPTIONAL} COARSE ARC VOLTAGE CONTROL FINE ARC VOLTAGE CONTROL A. Description of Controls 1. Power Switch — Turns machine on and off. 2. Coarse Arc Voltage Control — A five position selector switch which changes the arc voltage by approximately 4 volts when switched from one position to the next. (The minimum range is for solid wire only.) 3. Fine Arc Voltage Control — A continuously adjustable rheostat that gives approximately 5 volts of arc voltage control. This control gives overlapping ranges on each of the five coarse voltage control settings when using solid wire procedures, and - 8 - it gives overlapping ranges on each of the upper four coarse arc voltage control settings when using Innershield procedures. The Fine Arc Voltage Control is effective only while welding; it does not control the open circuit voltage. 4. Voltmeter — This meter reads the voltage at the output studs of the machine. The actual arc voltage at the workpiece is slightly lower due to the drop in the gun conductor cable and in the work cable. 5. Wire Speed — Controls the wire speed from 50 to 400 inches per minute. The control can be preset on the dial plate to the desired wire speed and the actual wire speed while welding will be very close to that value. 6. Wire Feed Circuit Breaker — This control has a dual function. It can be used as an on-off switch to completely stop wire feed and it functions as an overload circuit breaker. When the button is completely black the circuit breaker is closed and wire will feed when the gun trigger is pressed. Press the button once to turn off the wire feed. A white band will appear on the button. To turn the wire feed back on, press the button again. (See Maintenance Section.) B. Polarity Check to see that the cable coming from the conductor block on the wire feed unit goes to the output stud that is of the polarity required for the process that is to be used. (Refer to “Output Connections”, Page 6.) C. To Start the Welder Turn the “Power Switch” to “ON”. This lights the red pilot light next to the switch and starts the cooling fan. Operate the gun trigger for welder output and to energize the wire feed motor. D. Wire Reel Loading (30, 50 and 60 Pound Coils) 1. Open the side door for access to the wire feed compartment. To remove the wire reel from its shaft, grasp the spring loaded knob and pull it out. This straightens the knob so it seats into the shaft when released. Remove the reel. 2. Lay the reel flat on the floor, loosen the spinner nut and remove the cover plate. 3. Before cutting the tie wires, place the coil of electrode on the reel so it unwinds as the reel rotates clockwise. a. Be sure the coil is placed so the spring loaded arms will not interfere with the later removal of the coil tie wires. (See photo.) b. When loading .030 and .035" Lincoln electrode, be certain the coil is placed on the reel so the spring loaded arms are at the center of the slots in the cardboard coil liner. This provides the positive compression of the coil needed for trouble-free wire feeding. (See photo.) c. Put the cover plate on the reel so the four arms of the cover straddle the spring loaded arms of the reel proper. WIRE FEED COMPARTMENT Shown with optional K-341 Timer Kit and with top of case removed. 4. Tighten the cover as much as possible by hand. DO NOT hammer on the spinner nut arms. 5. Cut and remove only the tie wire holding the free end of the coil. Insert the free end into one of the holes in the cover and secure it by bending it back. Cut and remove the remaining tie wires. CAUTION: Always be sure the free end of the coil is securely held while the tie wires are being cut and until the wire is feeding through the drive rolls. Failure to do this will result in “back-lashing” of the coil, which may tangle the wire. A tangled coil will not feed so it must either be untangled or discarded._ 6. Replace the reel on the wire feeder. Grasp the shaft kn...
