SET-UP FOR FLUX CORE WELDING
The Eastwood MIG 180 comes factory set-up to weld with Solid Wire and Shielding Gas.
Flux Core does not require shielding gas.
Three changes to the Set-Up need to be made to MIG Weld with Flux Core wire:
- Reverse polarity from DCEP to DCEN.
- Install Flux Core wire.
- Position Drive Roller to accept Flux Core wire.
CHANGING THE POLARITY TO DCEN FOR WELDING WITH FLUX CORE WIRE
To use a Flux Cored wire, the Polarity of the short Integral Ground Connection Lead [d]
attached to the Front Panel must be reversed (FIG 14).
ELECTRIC SHOCK CAN CAUSE INJURY OR DEATH!
Disconnect Welder from power supply before beginning.
• Disconnect the Short, Integral Ground Connection Lead [d] from the Positive (+)
Connection Receptacle [e] by rotating the Rubber Insulator 1/2 turn Counter-
Clockwise and pulling outward.
• Align the key of the brass ferrule with the notch of the receptacle at the 12:00
position, then insert the Lead [d] onto the Negative ( - ) Connection Receptacle
[c], seat fully and rotate 1/2 turn Clockwise to lock (FIG 14).
• Insert and lock the Ground Clamp Cable into the (+) Positive Connection
Receptacle [e] (FIG 14).
POSITIONING DRIVE ROLLER FOR WIRE SIZE
The Eastwood MIG 180 Wire Drive Roller has twin grooves to accommodate both 0.023"
[6mm] and 0.030"/0.035" [0.8mm/0.9mm] wire.
The MIG 180 Drive Roller is factory set and up ready to use 0.030" (0.8mm) solid wire.
IMPORTANT NOTE: In this position, the actual, 0.030"/ [0.8mm] groove is inboard, un-
der the wire while the 0.8 marking for the 0.030" [0.8mm] wire is visible on the outward
face of the Drive Roller.
To Clarify; The stamped marking on the side of the drive roller indicates the size of the
groove on the opposite side of the roller (FIG 15).
Reverse the drive roller position according to the following procedure:
• Open the side door of the Welder to access the drive motor compartment.
• 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 16).
• Loosen and remove the Drive Roller Retaining Knob (FIG 16).
• 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 15).
• Reinstall the Drive Roller Retaining Knob on the shaft.
• Replace the Tension Arm and re-latch the Pressure Adjuster.
