SAFETY PRECAUTION 
ELECTRIC SHOCK can kill.
•Turn the input power off at the power source disconnect switch before attempting to connect the input power to the
•Only qualified personnel should perform this installation.
Electrode Routing
The electrode supply may be either from reels, Readi- Reels, spools, or bulk packaged drums or reels. Observe the following precautions:
a)The electrode must be routed to the wire drive unit so that the bends in the wire are at a mini- mum, and also that the force required to pull the wire from the reel into the wire drive unit is kept at a minimum.
b)The electrode is "hot" when the gun trigger is pressed and must be insulated from the boom and structure.
c)If more than one wire feed unit shares the same boom and are not sharing the some power source output stud, their wire and reels must be insulated from each other as well as insulated from their mounting structure.
WIRE DRIVE SPEED RANGE SELECTION
The rated speed and wire size range for each wire drive head is shown in the SPECIFICATIONS in the front of this section.
Control Speed Range Setting
The speed range is set up to match the wire feed head connected to the
10 Series Wire Drive Ratio Selection
The 10 Series type drives include two external gear sizes; a 1" dia. gear and a
The following procedure is for changing ratio of the 10 Series wire drive:
1)Pull open the Pressure Door.
2)Remove the Phillips head screw retaining the pin- ion gear to be changed and remove the gear. If the gear is not easily accessible or difficult to remove, remove the feedplate from the gearbox. To remove feedplate:
a)Loosen the clamping collar screw using a 3/16" Allen wrench. The clamping collar screw is accessed from the bottom of the feedplate. It is the screw which is perpendicular to the feeding direction.
b)Loosen the retaining screw, which is also accessed from bottom of feeder, using a 3/16" Allen wrench. Continue to loosen the screw until the feedplate can be easily pulled off of the wire feeder.
3)Loosen, but do not remove, the screw on the lower right face of the feedplate with a 3/16" Allen wrench.
4)Remove the screw on the left face of the feedplate. If changing from high speed (larger gear) to low speed (smaller gear), line the lower hole on the left face of the feedplate with the threads on the clamping collar. Line the upper hole with the threads to install larger gear for high speed feeder. If feedplate does not rotate to allow holes to line up, further loosen the screw on right face of feed- plate.
5)Install gear onto output shaft and secure with flat washer, lock washer, and Phillips head screw which were previously removed.
6)Tighten the screw on lower right face of feedplate.
7)
8)Feedplate will be rotated
a)Loosen the clamping collar using a 3/16" Allen wrench. The clamping collar screw is accessed from the bottom of the feedplate. It is the screw which is perpendicular to the feeding direction.
b)Rotate feedplate to the desired angle and tight- en clamping collar screw.
9)Make sure to properly set the switch (S2) code on the control board inside the control box for the new gear size installed. See OPERATION “Setting the DIP Switch” for setting instructions.
