DESIGN FEATURES AND
ADVANTAGES
• Excellent arc characteristics for optimum constant
voltage submerged arc and Innershield welding
performance.
• A control circuit designed to provide good starting
for a large variety of processes and procedures.
• Output Control Potentiometer that provides easy
single range continuous control.
• Output Control Switch that provides simple switch-
ing from local to remote control.
• Output Terminals Switch to energize output termi-
nals either local or remote.
• White neon pilot light to confirm that the Input
Contactor is energized.
• DC Ammeter and Voltmeter
• 42VAC 10 Amp auxiliary power available for the
wire feeder, circuit breaker protected.
• Single MS-type (14 pin) connector for wire feeder.
• 115VAC 15 Amp auxiliary power available for the
wire feeder, circuit breaker protected.
• 115VAC 15 Amp GFCI receptacle available on 60
Hertz models, circuit breaker protected.
• Multi-functional terminal strip for easy connection
of wire feeding control cables.
• Recessed output terminals to avoid any person or
object from accidentally coming into contact with
the output terminals and labeled " + " and " - " for
easy identification.
• Thermostatically protected power source.
• Electronic protection circuit to protect power
source against overloads.
• Input line voltage compensation to provide an
essentially constant output.
• SCR electronically controlled welder output pro-
vides extra long life, especially for highly repetitive
welding applications.
• Solid state 2 and 4 circuit for extra long life.
• Two circuit solid state control system provides
maximum performance and circuit protection.
• Low profile case provides maximum use of space.
• Convenient access to all controls.
• Output lead strain relief loops to prevent terminal
and cable damage.
• Easily removed case side, even when stacked.
• Outdoor operation because enclosure is designed
with air intake louvers that keep dripping water
from entering the unit. Transformer, SCR bridge,
and choke have special corrosion resistant paint
for added protection.
