WIRE DRIVE ROLL
The drive rolls installed with the POWER MIG® 216
have two grooves, one for .035"(0.9mm) wire and the
other for .045"(1.1mm) wire. Drive roll size is indicated
by the stenciling on the exposed side of the drive roll.
WIRE SIZE CONVERSION PARTS
The POWER MIG® 216 is rated to feed .025" through
.045" (0.6-1.1mm) solid or cored electrode sizes.
The drive roll kits and Magnum Pro 250L gun and
cable parts are available to feed different sizes and
types of electrodes. See Accessories and
Maintenance sections of this Instruction Manual.
