GENERAL DESCRIPTION
The 350-SA is a heavy duty engine-driven DC arc
welding power source capable of providing constant
current output for stick welding or DC TIG welding.
With the addition of the optional Wire Feed Module for
K1314-4, the 350-SA will provide constant voltage
output for running the LN-25, LN-23P or LN-7 wire
feeders. The Wire Feed Module is factory-installed on
the K1314-5 350-SA.
The output rating of the 350-SA is 350 amperes at 34*
arc volts at 25% duty cycle. Duty cycle is based on a
ten minute period; thus, the welder can be loaded at
rated output for 2.5 minutes out of every ten minute
period.
* The output rating at 60% duty cycle is
250 amps at 40V.
DESIGN SUMMARY
Control Panel
Both the engine and the welder controls are located
on one recessed panel at the exciter end of the
machine. The welder controls consist of a five step
“Current Range Selector” switch and a “Fine Current
Adjustment” rheostat. Each welder is equipped with a
“Start” button and an “Idler Control” switch. The
Perkins diesel uses a “Thermostart” button, and has a
“Stop” control.
On this panel is also mounted an engine temperature
gauge, a battery charging ammeter, an oil pressure
gauge, and the three prong grounded type auxiliary
power receptacle.
Copper Shunt Windings
For long life and dependable operation.
Engine Idler
The 350-SA is equipped with an electric automatic
engine idler. It automatically increases and decreases
engine speed when starting and stopping welder or
using auxiliary power. A built-in time delay permits
changing electrodes before the engine slows to its low
idle speed. The “Idler Control Switch” on the panel
locks the idler in full speed position when desired.
Auxiliary Power
3.0 kVA of nominal 115/230V, 60 Hz, AC

Output voltage is within ± 10% at all loads up to
rated capacity.
Welder Enclosures
The complete welder is rubber mounted on a rugged
steel base.
The output terminals are placed at the side of the
machine so that they are protected by the door. The
output terminals are labeled (+) and (-).
Remote Control
K924-1 (for K1314-4, -5 only) - (Field Installed).
Provides a receptacle switch and remote control box
with 100 ft cord for fine current and OCV adjustment
at the welding site.
Cranking System
A 12 volt electric starter is standard.
Air Cleaner
Heavy duty two stage dry type.
Muffler
A muffler to reduce engine noise is standard on the
diesel engine units.
Engine Hour Meter
A meter to record the hours of operation.
Diesel Engine Protection
The system shuts the engine down in the event of
sudden low oil pressure or high coolant temperature.
