3. Digital Wire Feed Speed (WFS) and Welding Amperage (A) (Right side LED display)
MIG mode
This digital meter is used to display the pre-set (preview) wire feed speed in IPM (inches per
minute) in MIG mode and actual welding amperage of the power source when welding.
During non-welding, the digital meter will display a pre-set (preview) value of wire feed speed.
This value can be adjusted by varying the Wire feed speed control knob (4).
NOTE!
The preview functionality provided on this power source is intended to
act as a guide only. Some differences may be observed between
preview values and actual welding values due to factors including the
mode of welding, differences in consumables/gas mixtures, individual
welding techniques and the transfer mode of the welding arc (dip
versus spray transfer). Where exact settings are required (in the case
of procedural work), it is recommended that alternate measurement
methods be utilized to ensure output values are accurate.
3.1
Wire
speed
indicator
The wire speed indicator illuminates when MIG mode is selected to identify that the digital
wire speed/amperage meter is previewing wire speed in IPM (inches per minute).
The wire speed indicator extinguishes when the user is MIG (GMAW/FCAW) welding or
depressing the MIG gun trigger and the digital wire speed/amperage meter displays actual
welding amperage of the power source.
4. Wire speed/amperage control
In MIG mode, the wire speed/amperage control knob adjusts the speed of the wire feed motor
(which in turn adjusts the output current by varying the amount of MIG wire delivered to the
welding arc). The optimum wire speed depends upon the material type and the welding
application. The setup chart on the inside of the wire feed compartment door provides a brief
summary of the required settings for a basic range of MIG (GMAW/ FCAW) welding
applications.
NOTE!
The preview functionality provided on this power source is intended to
act as a guide only. Some differences may be observed between
preview values and actual welding values due to factors including the
mode of welding, differences in consumables/gas mixtures, individual

5. MIG gun
adapter
(TWECO
style)
The MIG gun adapter is the connection point for the MIG gun. Refer section 5.6 Attaching the
ESAB fusion 180 A MIG gun for installation of MIG gun to the power source.
6. Positive
welding
output
terminal
The positive welding terminal is used to connect the welding output of the power source to the
appropriate welding accessory such as the MIG gun (via the MIG polarity lead), electrode
holder lead or work lead. Positive welding current flows from the power source via this dinse
type terminal. Insert and turn the male plug securely to achieve a secure electrical
connection.
WARNING!
Loose welding terminal connections can cause overheating and result in
the male plug being fused in the dinse terminal.
