6.3 250R MIG Welding Setup
1 Ensure the machine is correctly plugged into the main circuit
2 Proper PPE must be worn
3 Ensure workplace safety such as fume extraction is in place
4 Switch machine on using On/Off switch 12 at the back of the
machine
5 Open gas cylinder and set gas flow rate
6 The REM indicator light goes on when the power source and wire
feeder are connected. This means the wire speed feed 15 and
voltage 18 will need to be adjusted on the wire feeder control
panel
7 Set voltage and wire feed speed (the tables included in this
manual can be used as a guideline for voltage and wire speed
selection)
8 Voltage is set by adjusting voltage knob 18 on wire feeder
9 Inductance can be changed by adjusting the
power source. The value will be displayed on the power source
control panel while welding
10 Welding wire can be fed through the torch by selecting the
"Wire Inch" button 17 on the wire feeder
11 For certain types of self shielded flux cored wires it is required to
change the polarity. This can be achieved by switching the work
return lead and clamp from the negative dinse connector 8 to
the positive dinse connector 6. The pigtail needs to then change
from the positive dinse connector 6 to the negative dinse
connector 8.
NOTE
Refer to the Control Panels section for a complete explanation of
all functionalities.
