The Electronics Lab
is equipped to support the design and analysis
of analog and digital control systems.
The EMC Lab
is equipped to conduct electro-magnetic
interference testing.
The Power Lab
is equipped to build and test full-scale
prototype machines rapidly to support the
development of new power conversion
techniques. As new power electronic
components emerge they are evaluated
and implemented.

Power Electronics Design
The reliability of a welding power source is critical. Electronics improvements are the foremost
method of continually improving the reliability, efficiency, and performance of our power sources.
Lincoln invested in improving the dependability, durability, and efficiency of its inverters. Lincoln engineers
developed innovative solutions for power conversion. Extensive research is conducted in the electronics,
EMC, and power laboratories.
Reliability Testing
During Product Design
Environmental Stress
Screening (ESS) subjects the
machine to extreme conditions
of temperature and humidity.
Mechanical tests such as vibration and drop
testing provide evidence to the machine’s
durability and resistance to breaking.
Infrared thermal analysis is done
on power electronic assemblies in
the power electronics lab. This is
done at both the PC board level
and the machine level.
