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.
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.
7. MIG polarity lead
The polarity lead is used to connect the MIG gun to the appropriate positive or negative
output terminal (allowing polarity reversal for different welding applications). In general, the
polarity lead should be connected in to the positive welding terminal (+) when using steel,
stainless steel or aluminum electrode wire. When using gasless wire, the polarity lead is
generally connected to the negative welding terminal (-). If in doubt, consult the manufacturer
of the electrode wire for the correct polarity. Insert and turn the male plug securely to achieve
a secure electrical connection.
8. Negative welding output terminal
The negative 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), TIG torch
or work lead. Negative welding current flows to 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.
WARNING!
Loose welding terminal connections can cause overheating and result in
the male plug being fused in the dinse terminal.
WARNING!
Loose welding terminal connections can cause overheating and result in
the male plug being fused in the dinse terminal.
