WELD WIRE 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.
