*Tips about drive rollers: You'll see two different rollers provided. One will be on the machine and the other will be in a bag. If
you look very closely at the grooves, one has teeth and one does not. The one with the teeth is called the knurled drive roller
(FIG3) and is designed to be used with your flux core wire. The smooth drive roller is for solid core MIG wire(FIG4). The drive
roller will have markings on the front and back in two different sizes, in either millimeters or thousandths. A .06mm will handle
0.023 to 0.025 wire. Likewise a .08 will handle .030 wire. Be sure the correct size groove is in the outer position of the drive
assembly to match the size of the wire you will be using and reinstall. Do not over tighten the wire tensioner on the drive
mechanism.

3. Remove the spool retainer (2) by turning it counter clockwise.
4. Remove any plastic covering that may be on your new wire but do not un-secure the wire that is in the spool yet unless it
interferes with the following test. If it does, just secure the loose wire end with painters tape or similar to the rest of the
wire temporarily.
5. Place your wire spool on the idler roller with the wire set up to be fed from the bottom as seen in the photo. Before un-
securing the wire, replace the spool retainer and spring. Next roll the wire spool to be sure it turns freely with just a slight
drag.
