FITTING AND THREADING THE ELECTRODE
WIRE - ALWAYS USE ER70S-6 WELDING
WIRE WHEN WELDING STEEL.
1. Remove the wire spool clip from
the spool hub.
2. Unpack the spool of welding wire
from its protective packaging.
3. Place the spool of ER70S-6 weld-
ing wire onto the hub. The wire
is fed off the bottom of the
spool.
CAUTION
Look for wire protruding
from the center of the
spool. The protruding wire
is electrically HOT during
welding and must not touch
the machine. Cut this wire
flush with the spool.
4. Replace the spool clip on the
hub.
5. Unlatch the pressure roll arm
and swing it open.
6. Make sure the double v-groove
drive roll is installed to match
the wire size. To change the
wire size setting, remove the
drive roll, turn it over and
reinstall it on the shaft.

properly adjusted. When welding
steel, the gas flow rate is 30
CFH. When welding aluminum, the
gas flow rate is 40 CFH.
NOTE
The PBE180 must be turned
"ON" and the MIG torch
trigger depressed, before
