WIRE FEED DRIVE ROLL KITS

NOTE: The maximum rated solid and cored wire sizes for each wire drive head and selected drive ratio is shown on the SPECIFICATIONS in the front of this section.

The electrode sizes that can be fed with each roll and guide tube are stenciled on each part. Check the kit for proper components.

Synergic 7F Wire Drives (K679) use 4-Roll drive roll kits with 2 driven rolls, per Table C.1 in ACCES- SORIES. These kits are common with those used for the 4-Roll LN-7 GMA and LN-9 GMA Lincoln Wire Feeders, but are not common with those used with the 10 Series wire drive units. Installation instructions are included with the kits.

10 Series Wire Drives use 4-Roll drive roll kits with 4 driven rolls, per Table C.1 in ACCESSORIES.

PROCEDURE TO INSTALL DRIVE ROLL AND WIRE GUIDES

WARNING

ELECTRIC SHOCK can kill.

•Do not touch electrically live parts such as output terminals or internal wiring.

•When inching with gun trigger, electrode and drive mechanism are “hot” to work and ground and could remain energized several seconds after the gun trigger is released.

•Turn OFF input power at welding power source before installation or changing drive roll and/or guide tubes.

•Welding power source must be connected to system ground per the National Electrical Code or any applicable local codes.

•Only qualified personnel should perform this installation.

Observe all additional Safety Guidelines detailed throughout this manual.

Synergic 7F Wire Drive 4-Roll Kits (KP655 and KP656)

1)Turn OFF welding power source.

2)Release both quick release levers by sliding the levers sideways into the open positions.

3)Remove clamping screw & clamping collar from the drive shaft closest to the incoming side of the feeder.

4)Install drive roll onto keyed shaft. (Do not exceed the maximum wire size rating of the wire drive.) Replace collar and tighten clamping screw.

5)Back out the set screw for the middle guide tube. Install the middle guide tube and slide it up against the drive roll. DO NOT TIGHTEN THE MIDDLE GUIDE AT THIS TIME.

6)Install the outgoing drive roll following the same procedure as steps 3 & 4.

7)Center the middle guide between the two drive rolls and tighten in place.

8)Back out the screws for the incoming and outgoing guide tubes.

9)Install the longer guide tube in the rear hole near the incoming drive roll. Slide the tube in until it almost touches the roll. Tighten in place.

10)Install the remaining guide tube in the front hole. Be certain that the proper plastic insert is used. Fine wire chisel point tube must have largest radius next to drive roll. Tighten in place.

11)Re-latch both quick release levers.

12)To start new electrode, straighten the first 6" (150mm) and cut off the first 1" (25 mm). Insert free end through the incoming tube. Press gun trigger and push wire into the drive roll.

TO SET IDLE ROLL PRESSURE, see “Idle Roll Pressure Setting” in OPERATION.

10 Series Wire Drive Roll Kit Installation (KP1505 and KP1507)

1)Turn OFF Welding Power Source.

2)Pull open Pressure Door to expose rolls and wire guides.

3)Remove Outer Wire Guide by turning knurled thumb screws to unscrew from Feedplate.

4)Remove drive rolls, if any are installed, by pulling straight off shaft. Remove inner guide.

5)Insert inner Wire Guide, groove side out, over the two locating pins in the feedplate.
