To select MIG welding process, proceed as follows:
Follow safety precautions according to Section 1.
Prepare unit according Section 3.
Using a cable with a proper adapter, con- nect gun to the MIG gun connector.
Connect work clamp cable to the WORK connector.
If using a
Check coolant level after attaching torch coolant hoses and running cooler. Be sure coolant appears in upper half of indicator. Add coolant if necessary (see Section
If a remote control is desired, connect it to the Remote Control receptacle.
Connect gas hose to gas connector on rear of unit.
Turn unit On.
Allow time for unit to complete its start up cycle.
Set MIG welding process using P3 push button.
Purge air from gun gas hose using P8 push button (see Section
4-12. Selecting Manual MIG Welding
E1 | D1 | D2 | E2 |
P3 | P6 | P7 |
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.
D1 value is default voltage setting of 18.5 V (range is 10.0 V to 50.0 V).
Use E1 to change voltage.
D2 value is default wire feed speed setting of 5.0 m/min (range is 1.0 m/min to 20.0 m/min).
Use E2 to change wire feed speed.
Select trigger mode using P6 push button (see Section
Setting Inductance
Press P7 until L17 LED illuminates.
L17 ON selects Inductance. Default setting is 100% (range is 1% to 200%). D1 and D2 return to main display after several seconds.
.Higher inductance setting produces a softer weld puddle and less spatter, but arc starts may be more difficult. Lower induc- tance setting produces a stiffer weld puddle and more spatter, but arc starts may be easier.
