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.
• Designed to the IECEN 60974-1 standard.
• Standards - IECEN 60974-1, NEMA EW 3, CSANRTL/C.
• Environmental rating IP21S.
QUALITY AND RELIABILITY
Design
Safety, reliability and service-ability are built into Lincoln’s Inverter
design.
• Open construction for preventative maintenance and diagnostics.
• Thermostatically protected.
• Electronic output over-current protection and electronic input
over-voltage protection.
• Operating Temperature Range: -20C to +40C.
• Storage Temperature Range: -40C to +40C.
• Double insulation and varnish on main transformer.
• Shielded Heavy Duty Input Contactor in tightly sealed environ-
mental enclosure.
• Electrical connections coated with insulating compound for long
term reliability in harsh environments.
• Automotive grade sleeves protect leads from abrasion.
• Tough PC Boards - tray mounted, completely encapsulated,
double locked harness connectors, environmentally protected
connectors, electrical silicone grease, high current rating.
• Efficient Cooling System with Industrial Motor with sealed bear-
ings and metal fan blade.
• Fan-As-Needed - reduces power consumption and the amount of
debris that gets drawn into the machine by shutting the fan down
when it is not needed.

Cooling System
Power electronics innovations like lightweight
inverters and high speed chopper are common,
but Nextweld’s power electronics provide fabrica-
tors with a highly efficient system that are reliable
and can adapt easily to new operations. State-of-
the-Art Inverter technology provides high power
efficiency, excellent welding performance and a
lightweight, compact design. Lincoln inverters
undergo rigorous environmental, mechanical and
weld testing in the design/production process to
ensure ruggedness and reliability.
