ZR-10 Approximate Fuel Consumption

Low Idle - No Load
2400 RPM
High Idle - No Load
3700 RPM
AC CC Weld Output
225 Amps @ 25 Volts
DC CC Weld Output
210 Amps @ 25 Volts
DC CV Weld Output
200 Amps @ 20 Volts

Auxiliary Power

9000 Watts
" CONTROL" SWITCH
Provides a fine welding current adjustment within the
Range Switch settings in the STICK/TIG mode and
welding voltage control with the Range switch set in
the wire feed mode.

"IDLER" SWITCH

The idler switch has two positions, "HIGH" and
"AUTO".
When in "HIGH" ( ) position, the engine will run
continuously at high idle.
When in "AUTO" ( /
operates as follows:

• WELDING

When the electrode touches the work, the welding
arc is initiated and the engine accelerates to full
speed.
After welding ceases (and no auxiliary power is
being drawn), the engine will return to low idle
after approximately 10 to 16 seconds.
• AUXILIARY POWER
With the engine running at low idle and auxiliary
power for lights or tools is drawn (approximately
100-150 watts or greater or 1500W on 460v 3ø)
from the receptacles, the engine will accelerate to
high speed. If no power is being drawn from the
receptacles (and not welding) for 10-16 seconds,
the idler reduces the engine speed to low idle.

STARTING / SHUTDOWN INSTRUCTIONS

STARTING THE ENGINE

WARNING
• Do not touch electrically live parts
of electrode with skin or wet
clothing.
• Keep flammable material away.
• Insulate yourself from work and
ground. Wear eye, ear, and body
protection.
• Keep your head out of the fumes.
• Use ventilation or exhaust to
remove fumes from breathing zone.
Be sure all Pre-Operation Maintenance has been per-
formed. Also, read the Engine Owner's Manual.
Remove all loads connected to the AC power recepta-
cles. To start the engine, set the "Idler Control" switch
in the Automatic ( /
Use the choke control as follows:
Honda Engine - Always pull the choke control out
when starting the engine; cold. Place the "Engine"
switch in the "ON" position.
Push the "START" button and crank the engine until it
starts. Release the button as soon as the engine
starts. Do not push the "START" button while the
engine is running because this will cause damage to
the ring gear and/or starter motor. After the engine
has started, slowly return the choke control to the full
"in" position (choke open).
After running at high engine speed for 10-14 seconds,
the engine will go to low idle.
Allow the engine to warm up by letting it run at low idle
for a few minutes.

STOPPING THE ENGINE

Remove all welding and auxiliary power loads and
allow engine to run at low idle speed for a few minutes
to cool the engine.
Stop the engine by placing the "Engine" switch in the
"OFF" position.
A fuel shut off valve is not required on the ZR-10
because the fuel tank is mounted below the engine.
