Power supply product reliability tests exceed 10 years

Miyachi Unitek tests power supply products, some of which reportedly have been running continuously in 105° temperatures for over a decade.

Miyachi Unitek Corp., a manufacturer of welding equipment and laser processing systems, for decades has allegedly been assessing its power supply technologies for effectiveness, reliability and durability by putting its power supply products to the test, running them continuously in an extreme 105° environment to prove the design’s merit.

The testing occurs in an area in the factory referred to as “the torture room” for its high temperatures and constant clatter of weld heads. The torture room holds a variety of Miyachi’s resistance welding power supply units, including advanced capacitive discharge welders and full-featured AC resistance weld controls. Many units have been run continuously for 10 to 15 years, for a total of 15 to 25 million cycles.

The objective of the torture room is to understand how the products perform over time. Miyachi Unitek’s engineers determine what works well and what breaks down after years of use, and they use that information to improve the next generation of equipment.

The torture room also allows Miyachi Unitek to make better guarantees about their technologies’ performance. “When your sales person praises a system’s reliability, we know it’s the truth because of our tests,” said Kevin Gunning, director of quality, service and support. “Our thorough assessments allow us to confidently say our equipment is robust enough for the long haul.”

Annual Salary Survey

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.

There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.

But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
