POSITIONING THE DRIVE ROLLER
The Eastwood MP140i Wire Drive Roller has twin grooves to accommodate both
0.023” [6mm] and 0.030”/0.035” [0.8mm/0.9mm] wire.
The MP140i Drive Roller is factory set up ready to use 0.023” [0.6mm] solid wire.
IMPORTANT NOTE:
In this position, the narrower 0.023” [0.6mm] grove is inboard,
under the wire while the 0.6 marking is visible on the outward face of the Drive Roller
(FIG 13)
.
0.023” [6mm] wire can be used with the Drive Roller in this position. If 0.030”
[0.8mm] or 0.035” [0.9mm] wire is to be used, the drive roller position needs
to be reversed.
Reverse the drive roller according to the following procedure:
• Open the side door of the Welder to access the drive motor compartment
(FIG 14)
.
• Push the Pressure Adjuster rearward, pivot it down and out of the way then
pivot the Tension Arm up away from the Drive Roller
(FIG 15)
.
• Loosen and remove the Drive Roller Retaining Knob
(FIG 13)
.
• Remove the Drive Roller and view the wire sizes stamped on each side of
the Roller.
• Install the Drive Roller in the orientation so that the chosen wire size stamping
is facing outward making sure shaft key aligns with the Drive Roller keyway
(FIG 13)
.
• Reinstall the Drive Roller Retaining Knob on the shaft.
• Replace the Tension Arm and re-latch the Pressure Adjuster.
INSTALLING THE WIRE SPOOL
The Eastwood MP140i can be used with either a 4” or an 8” wire spool. A 4” Spool
fits directly on the Spool Shaft. To use the larger 8” spool, the included 8” Spool
Adaptor is necessary.
To install a 4” Wire Spool:
• Open the door of the Welder and remove the Spool Retaining Knob, Spacer,
and 8” Spool Adaptor from the Wire Spool Spindle.
• Slide the 4” Wire Spool onto the Spindle and reinstall the Spacer and the Spool
Retaining Knob then place the 8” Spool Adaptor in a safe place if it is needed
in the future.
SETTING THE WIRE SPOOL PRESSURE ADJUSTER
• To set the tension on the wire, incrementally tighten the Spool Retaining Knob
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 freely spin on the shaft and unspool
all of the wire. If the tension is too tight, the Drive Roller will have difficulty
pulling the wire off the spool and some slipping may occur.
To install an 8” Wire Spool:
• Open the door of the Welder and remove the Spool Retaining Wingnut and
Spacer from the Wire Spool Spindle.
• Slide the 8” Wire Spool Adaptor into the center of the Wire Spool.
• Slide the 8” Wire Spool Adaptor with the wire spool installed onto the spindle
and reinstall the Spacer and the Spool Retaining Knob.
• Set tension on the wire as noted in above steps.
