Installing Wire Spool - Eastwood MIG 175 Assembly & Operating Instructions

INSTALLING WIRE SPOOL

The Eastwood MIG175 can be used with either a 4"or an 8" Wire Spool. To use the larger 8" spool an included adaptor is necessary.
To install a 4" Wire Spool:
1. Open the door of the welder and remove the wing nut (Fig. 2G), spacer (Fig. 1G), and 8in Spool Adaptor (Fig. 3G)
from the Wire Spool Spindle.
2. Slide the 4" Wire Spool onto the spindle and reinstall the spacer and the wing nut and place the 8in Spool Adaptor
(Fig. 3G) in a safe place if it is needed in the future.
3. To set the tension on the wire, tighten the wing nut till there is a slight resistance to spinning
the wire spool on the spindle. If the tension is set too loose the wire spool will spin on the
shaft and unspool all of the wire. If the tension is too tight, the drive roller will have issues
pulling the wire off the spool and some slipping may occur.
NOTE: Hold exposed wire end to keep the spool from unraveling.
To install an 8" Wire Spool:
1. Open the door of the welder and remove the wing nut, spacer, and 8" Spool Adaptor
from the Wire Spool Spindle.
2. Slide the 8" Wire Spool Adaptor into the center of the wire spool.
3. Slide the 8" Wire Spool Adaptor with the wire spool installed onto the spindle and
reinstall the spacer and the wing nut.
4. To set the tension on the wire, tighten the wing nut till there is a slight resistance to spinning
the wire spool on the spindle. If the tension is set too loose the wire spool will spin on the shaft
and unspool all of the wire. If the tension is too tight, the drive roller will have issues pulling the
wire off the spool and some slipping may occur.
CONNECTING THE WELDER TO A POWER SOURCE
The Eastwood MIG175 welder requires a dedicated 220 VAC 30 Amp grounded outlet protected by a time delay breaker.
The MIG175 is equipped with a NEMA 6-50P Plug which requires a NEMA 6-50R outlet to be connected.
THREADING WELDING WIRE THROUGH THE
DRIVE MOTOR TO THE WELDING GUN
1. Unlock the Pressure Adjuster (Fig. 1H) on the wire tensioner and
lift up the rocker arm (Fig. 2H). Insure that the wire drive wheel
is appropriate to the welding wire size, see above describing the
installation to wire feed roller installation.
2. Pull out the welding wire (Fig. 3H) from the welding wire spool
carefully. NOTE: Do not let go of the wire prior to step 5 or
the entire spool will unravel and be useless.
3. Cut off the small piece of the curved segment at the front of
welding wire and straighten the welding wire approximately
3.0" long.
4. Thread the welding wire through the guide pipe (Fig. 4H) and over
the wire feed roller (Fig. 5H) and into the torch hole (Fig. 6H).
5. Reattach the rocker arm (Fig. 2H) and reset the Pressure Adjuster (Fig. 1H) on the wire feeder (now the welding wire can
be fed smoothly).
6. Remove the contact tip and nozzle from the MIG Gun.
7. Turn on the machine and set the wire speed about 1⁄2 on the scale.
8. With the gun pointed away from you and others, depress the trigger to begin feeding wire. NOTE: Watch the drive roller
to see if any slipping is occurring between the roller and the wire—if so turn the machine off and tighten the Pressure Adjuster
