A CLOSER LOOK
Rugged Testing and Reliability
All Lincoln inverters are fully tested for reliability before and after assembly.
• Each machine undergoes a functional weld test to ensure performance.
• Lincoln inverters are operated in an environmental chamber under extreme conditions
of temperature and humidity.
• Mechanical testing, including vibration and drop testing is performed.
• Extensive temperature testing is performed to ensure that all components are running
within allowable range.
• Three-year warranty on parts and labor.
• Manufactured under a quality system certified to ISO 9001 requirements and ISO 14001
environmental standards.
• Designed to the IEC/EN 60974-1 standard. Meets tough NEMA EW 1,
CSA NRTL/C standards.
• Meets rigorous IP23S environmental rating.

UALITY AND RELIABILITY
Robust Design
Safety, reliability and serviceability are built into Lincoln’s inverter design.
• Invertec inverter models operate at a high efficiency (88-90%) with a 95% minimum
power factor at rated output and are capable of operating from a universal 3 phase
input voltage (208 to 575 volts).
• Thermostatically protected.
• Electronic output over-current protection and electronic input over-voltage protection.
• Operating Temperature Range: -20ºC to +40ºC.
• Storage Temperature Range: -40ºC to +40ºC.
• Double insulation and varnish on main transformer.
• Shielded heavy duty input contactor in tightly sealed environmental enclosure.
• Tough PC Boards — potted and trayed, filled with epoxy, double locked harness
connectors, environmentally protected connectors, electrical silicone grease, high
current rating. Extra attention to detail provides excellent protection from dirt, dust
and the environment.
• Efficient Cooling System with industrial motor with sealed bearings and metal fan blade.
• Fan-As-Needed
™
— reduces power consumption, damaging thermal cycling and the
amount of debris that gets drawn into the machine by shutting the fan down when it
is not needed.
