INSTALLING THE WIRE SPOOL

The Eastwood MIG 140 can be used with either a 4” or an 8” wire spool. A 4” Spool fits 
directly on the Spool Shaft and the included, pre-installed 8” Spool Adapter must be 
removed and placed in a safe location for future use.
To use the larger 8” spool, the included, pre-installed 8” Spool Adaptor must be used.

TO INSTALL A 4” WIRE SPOOL

•  Open the door of the Welder and remove the Spool Retaining Wingnut, Spacer, 

and 8” Spool Adaptor from the Wire Spool Spindle 

(FIG 9)

.

•  Pull out the welding wire from the wire spool carefully. 

IMPORTANT NOTE:

 

DO NOT

 let go of the wire or the entire spool could unravel.

•  With the wire feed 

oriented forward and from the underside of the spool

slide the 4” Wire Spool onto the Spindle and reinstall the Spacer and the Spool 
Retaining Wingnut then place the 8” Spool Adaptor in a safe place if it is needed 
in the future 

(FIG 10)

DO NOT

 unravel wire at this point.

SETTING THE WIRE TENSION ADJUSTER

•  To set the tension on the wire, incrementally tighten the Spool Retaining Wingnut 

at the center of the Spindle 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 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 included 8” Wire Spool Adaptor into the center of the Wire Spool.
•  With the wire 

feeding forward from the underside of the spool

, slide the 8” 

Wire Spool Adaptor with the wire spool installed onto the spindle and reinstall the 
Spacer and the Spool Retaining Wingnut.

•  Set tension on the wire as noted in above steps.
