4-10. Preparing Unit For MIG Welding
To select MIG welding process, proceed as
follows:
Follow safety precautions according to
Section 1.
Prepare unit according Section 3.
Using the proper cable bundle, connect
unit to the wire feeder (see Wire Feeder
manual).
Using a cable with a proper adapter, con-
nect gun to the MIG gun connector on wire
feeder (see Wire Feeder manual).
Connect work clamp cable to the WORK
connector.
If using a water-cooled gun, connect input
coolant hose to blue quick connect fitting
and return coolant hose to red quick con-
nect fitting.
.
Check coolant level after attaching
torch coolant hoses and running cool-
er. Be sure coolant appears in upper
half of indicator. Add coolant if neces-
sary (see Section 3-9).
If a remote control is desired, connect it to
the Remote Control receptacle on the wire
feeder (see Wire Feeder manual).
Turn unit On.
Allow time for unit to complete its start up
cycle.
Set MIG welding process using P3 push
button.
4-11. Selecting Manual MIG Welding
Set Manual MIG welding process using P3 push button.
In Manual MIG mode, the operator may need to adjust main welding
parameters for specific arc characteristics. Wire feed speed and arc
voltage will appear on D1 and D2.
During Setting :
D1 value is default voltage setting of 18.5 V (range is 10.0 V to 50.0
V).
D2 value is default wire feed speed setting of 5.0 m/min (range is 1.0
m/min to 20.0 m/min).
During MIG Welding:
D1 value is Measured Welding Voltage in Volts.
D2 value is Measured Welding Amperage in Amperes.
See Wire Feeder manual for all other remaining manual MIG set-
tings.
Setting Cooler Status
.
Be sure that cooler is turned on for water-cooled torch to prevent
damage to torch components.
Use E1 to change D1 to W
−
ON.
D2 value is default setting of ON.
Use E2 to change D2 value to OFF, if applicable.
