Function Guide
1. Digital Meters display preset amperage or
voltage while not welding. Displays actual
amperage and voltage while welding and for
5 seconds after welding has stopped.
Meter Maintenance Functions*
• Hour Meter: with engine off, place Engine
Control switch in the first RUN/IDLE
position to view engine hours.
• Oil Change Interval: with engine off, place
Engine Control switch into the second
RUN/IDLE position to see hours before next
oil change. Oil hours start at 100 and count
down to 0 (oil change due).
Note: Negative hours indicated when past
recommended oil change interval.
To Reset: Flip Engine Control switch from the
RUN/IDLE to RUN position 3 times.
2. Four Preset DIG Settings* offer the best arc
characteristics for different electrodes and
joint designs. The combined DIG and
Process switch along with preset DIG
settings makes it easy to set without the
complication of multiple switches.
DIG Settings
• Soft arc and smooth 7018 performance.
• Medium-soft driving arc.
• Medium-stiff driving arc.
• Driving arc such as pipe welding.
3. Adaptive Hot Start ™ * (Stick) automatically
sets starting amperage for great arc starts.
4. Great MIG/FCAW Performance with
voltage-sensing wire feeders.
5. Lift-Arc ™ /Scratch Start TIG* with Auto-Stop ™
provides great DC starts with both starting
techniques. Auto-Stop allows the arc to be
stopped without the loss of shielding gas.
6. Standard 14-Pin Receptacle for simple
connection of remote controls (not for wire
feeder usage). It features Auto Remote
Sense
™ * which automatically switches from
Panel to Remote Amperage/ Voltage (A/V)
control with remote connected. Eliminates
confusion of the Panel/Remote A/V switch.
7. Front Panel Fuel Gauge* LEDs indicate
fuel level. The “E” LED lights only when
fuel is low.
8. Speed Control Switch locks engine speed
at 1800 RPM for uninterrupted 60 Hz
generator power and light welding loads.
9. Engine Choke Control
