Installing Welding Wire; Feeding Welding Wire - Eastwood MIG 250 Assembly & Operating Instructions

INSTALLING WELDING WIRE

The MIG 250 can be used with either a 4" or 8" Wire Spool. To use the larger 8" spool an
included adapter is necessary.
To install a 4" Wire Spool:
1. Open the door of the welder and remove the wing nut, spacer and 8" Spool Adapter
from the wire Spool Spindle.
2. Slide the 4" Wire Spool onto the spindle and reinstall the spacer and wing nut (Fig. G).
Place the Spool Adapter in a safe place for if it is needed in the future.
3. To set the tension on the wire, tighten the wing nut till there is a slight resistant to
spinning the wire spool. If the tension is set too loose the wire spool will spin on the
shaft and un-spool the wire. If the tension is too tight, the drive roller will have issues
pulling the wire and feeding issues will occur.
To install an 8" Wire Spool:
1. Open the door of the welder and be sure the 8" spool adapter is installed on the spindle.
If it has been previously removed, reinstall it (Fig. H).
2. Align the pin on the spool adapter with the hole on the wire spool and slide the spool
over the adapter making sure the pin on the adapter goes into the hole in the spool.
3. To set the tension on the wire, tighten the wing nut until 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 un-spool the wire. If the tension is too tight, the drive roller will
have issues pulling the wire and feeding issues will occur.

FEEDING WELDING WIRE

1. Turn Power Switch off and disconnect welder from power supply.
2. Unlock the Pressure Adjuster on the Wire Tensioner by pushing it
towards the front of the welder.
3. Lift up the Rocker Arm so that it is out of the way.
4. Ensure that the Drive Roller size is appropriate to the welding wire
size; see page 7 on how to change the Drive Roller.
5. Pull out the welding wire from the welding wire spool carefully.
NOTE: DO NOT LET GO OF THE WIRE PRIOR TO STEP 5 OR
THE SPOOL WILL UNRAVEL RENDERING IT USELESS.
6. Cut off the small piece of the curved segment at the front of
welding wire and straighten the welding wire approximately
3.0" long.
7. Thread the welding wire through the guide pipe and over the wire feed roller and into the torch hole.
8. Reattach the rocker arm and reset the Pressure Adjuster on the wire feeder.
9. Remove the contact tip and nozzle from the MIG Gun.
10. Turn on the machine.
11. With the gun pointed away from you and others, depress the Quick Feed button to feed the wire through the gun cable. Stop feed-
ing the wire once the wire has come a few inches out of the end of the MIG Gun. 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 1⁄2 turn and test again.
