Lincoln Electric IM613-B manual Ratio Change Procedure

A-5 INSTALLATION A-5

RATIO CHANGE PROCEDURE:

1)Power down the Power Feed by turning OFF its companion PowerWave power source. For maxi- mum safety, disconnect the control cable from the Power Feed.

2)Pull open the Wire Feeder’s Compartment Door.

3)Remove the Feedplate per the following:

a)Disconnected the Electrode from the Feedplate

b)Pull open the Wire Drive Pressure Door.

c)Using a 3/16" Hex Key Wrench remove the two screws that secure the Feedplate to the Interface Plate. These screws are located just below and to the right and just below and to left of the lower drive gears.

d)Swing the rear of the Feedplate out towards the front of the machine which will allow it to be pulled back and out of the machine.

Note: The shielding gas hose and gun leads are still attached to the Feedplate. This is OK provided that the Feedplate is setting on a suitable surface such that no excess tension is being place on the gas hose and gun leads. If necessary remove the gas hose and disconnect the leads.

4)Remove the pinion gear as follows:

a)Using a phillips head screwdriver remove the screw that secures the gear to the output shaft of the gearbox and remove the gear.

b)Lightly cover the output shaft with engine oil or equivalent. Install appropriate size gear(small gear for low speed and a large gear for high speed) onto output shaft and secure with flat washer, lock washer, and Phillips head screw which were previously removed.

6)Re-attach Feedplate (and gas hose and gun leads if they were removed) that was removed in Step 3 and reconnect the Electrode Cable.

Note: The screws that secure the Feedplate to the Interface Plate must go thru the insulator bushings in the Feedplate.

7)Close the Wire Drive Pressure Door and Wire Feeder’s Compartment Door.

8)Set the High/Low Dip Switch on Feed Head PC board as follows:

a)Remove the left case side as follows:

-Remove 4 screws that directly secure the case side

-Loosen the 3 screws that secure the lower skid rail. This will free the case side edge and allow it to be lifted up and removed.

Note: PF-11's that have been installed horizontally on top of the Power Source will need to remove the Mounting Bracket in order to access the the left case side.

b)Locate the 8-position DIP switch (S1) on the Feed Head PC board. The setting will be made on the bottom most switch, DIP switch #8.

c)Using a pencil or other small object, to slide the switch left, to the “OFF" position, when the low speed gear is installed. Conversely, slide the switch right, to the “ON" position, when the high speed gear is installed. Refer to the diagrams below.

Setting for Low Speed Setting for High Speed

Note: Be sure that the woodruff key remains secured to the output shaft during the gear change.

5)Position the Motor/Gearbox as follows:

a)There are 4 screws that secure the Motor/Gearbox to the Interface Plate. Using a 3/16" Hex Key Wrench remove the 2 upper screws and loosen (but don’t remove) the 2 lower screws.

b)Slide the Motor/Gearbox to the

c)Secure in position with flat washers, lock wash- ers, and socket head screws that were previ- ously removed and loosened.

d)Replace the left case side and screws(and Mounting Bracket if required). The PC board will “read” the switch at power up, automatically adjusting all control parameters for the speed range selected.
