IDLER OPERATION
Start the engine with the "Idler" switch in the "High" position.
Allow it to run at high idle speed for several minutes to warm the
engine. See Specifications for operating speeds.
The idler is controlled by the "Idler" toggle switch on the welder
control panel. The switch has two positions as follows:
1. In the "High"
position, the idler solenoid deactivates,
and the engine goes to high idle speed. The speed is con-
trolled by the governor.
2. In the "Auto"
/
lows:
a. When welding or drawing power for lights or tools (approxi-
mately 100 watts minimum) from the receptacles, the idler
solenoid deactivates and the engine operates at high idle
speed.
b. When welding ceases or the power load is turned off, a pre-
set time delay of about 15 seconds starts. This time delay
cannot be adjusted.
c. If the welding or power load is not re-started before the end
of the time delay, the idler solenoid activates and reduces
the engine to low idle speed.
RESIDUAL CURRENT DEVICE READY (ONLY FOR 12459)
The SA-400I is configured to allow for the addition of a Residual
Current Device (RCD) to protect the 240V Single Phase
Receptacle. The auxiliary power area on the front panel of the
SA-400I has a hole sized and shaped to accept a typical 2-pole
(RCD) along with a protective rubber boot. A cover plate with a
label "RCD Ready" covers the hole and secures a mounting
bracket on the backside of the panel.
NOTE: the RCD should be rated for at least 15 amps. There are
many suppliers of RCDs. Some examples are:
• Allen Bradley, part number 1492-RCD2A40
• Clipsal, part number 4RC225/30
The protective boot can be used on both RCDs & can be
obtained from:
• APM-Hexseal, part number HE-1035
See Section F-3 Diagrams of this Operator's Manual for
instructions on installing an RCD and protective rubber boot.

AUXILIARY POWER
If GFCI is tripped, See the MAINTENANCE section for detailed
information on testing and resetting the GFCI.
The AC auxiliary power, supplied as a standard, has a rating of
3.0 KVA of 120/240 VAC (60 hertz). Set fine current adjustment
at 100 for maximum auxiliary power.
With the 3.0 KVA, 120/240 VAC auxiliary power, one 120V duplex
protected by GFCI and one 240V duplex, grounding type
receptacle with 2 pole, 15 amp circuit breaker.
One 240 VAC European (IEC-309) 16 AMP receptacle is protected
by a 15 AMP 2-pole circuit breaker, that provides 3.0 KVA of
continuous power. Maximum current is 15 AMPs (only on code
12459).
The rating of 3.0 KVA permits a maximum continuous current of
13 amps to be drawn from the 240V duplex receptacle. 20 amps
can be drawn from the 120V duplex receptacle. The total
combined load of all receptacles is not to exceed 3.0 KVA.
An optional power plug kit is available. When this kit is specified,
the customer is supplied with a plug for each receptacle.
