whatever mode and parameter settings were last set will remain as the current settings the next time the unit is energized.
4-2. MIG Mode
In MIG mode, VOLTS is lit under left display and WIRE SPEED is lit under right display. Left knob is used to adjust
welding voltage within a range of 14-32 volts, and right knob is used to adjust wire feed speed within a range of 25-700
IPM. Refer to weld chart in front compartment for proper parameter settings according to wire type, shielding gas, and
material type and thickness.
4-3. Jog Mode
If gun trigger is pressed and held for more than 3 seconds without striking an arc, unit will automatically shut off weld
power. For MIG guns, shielding gas will shut off after 1 minute, and for spool guns, shielding gas will continue to flow
