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.

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.
