CASE STUDY
ROTOCON Ground Clamps Provide Quick ROI for Rotary Tank Welding Applications
Challenge
With over 100 years of experience in pioneering the compressor, air conditioning, refrigeration industry, Meridian Laboratory was approached by this manufacturer with challenges they faced in rotary tank welding applications. The company’s manufacturing process included using conventional brushed, rotary welding grounds.
Conventional brushed rotary grounds rely on metal on metal contacts to transfer current from the rotating to stationary portions of a machine. While simple in design and construction, there are numerous drawbacks associated with using conventional brushed rotary welding grounds. In fully and semi-automated rotational welding fixtures the machine relies on a fixed current setting to weld each seam. Over time, as a brushed rotary ground wears and changes in contact resistance, this increase in contact resistance leads to higher voltage drop and poor welding penetration. The end result is a greater amount of scrapped parts which did not meet the high-quality standards the manufacturer is known for.
Solution
The company learned about Meridian Laboratory’s ROTOCON MC-Series rotary electrical grounds and the wide array of models, designs, and capabilities spanning from 250 to 10,000 amperes. They then retrofitted their existing equipment, replacing all brushed ground clamps with maintenance-free ROTOCON rotary grounds. After installation, the customer quickly realized the gains of consistent and level current flows while eliminating the greasing and maintenance.
Key Statistics
- Consistent and low contact resistance provided steady stable current flow
- 100% maintenance free and arc free design allows for uninterruptable machine output and usage
- Fewer defective end products provides quick return on investment

Excellent service! We faced Meridian with a difficult part to make and asked for perfection. They took the challenge on … More and through repeated effort and determination, Vance and the team were able to get us the "perfect" product we needed. Although this was undoubtedly a frustrating project for all involved, they saw it through and proved Meridian Laboratory to be exactly the company we needed and want to work with in the future. Great work!

Adam and the crew at Meridian Laboratory were a pleasure to work with! Adam was extremely helpful, knowledgeable, and responsive. … More A slipring was purchased through Adam for the use of a university engineering capstone project, he was eager to help and very nice throughout the entire process to ensure our needs were satisfied. The slipring shipped and delivered in a timely manner and once the unit was received, all expectations were exceeded. The fit and finish of the slipring was great, and it performed exactly as expected. I highly recommend Meridian Laboratory if you require the use of a slipring, as I cannot say enough good things about the team over there and their American made products

We contacted Adam Ellingson of Meridian Laboratory about acquiring a high-speed 3 channel ROTOCON slip-ring for our university … More capstone project. Mr. Ellingson was gracious enough to provide our team with a 6 channel slip-ring that performed excellent out of the box. The slip-ring assembly feels precisely machined and spins true with little mechanical resistance. It was the perfect product for testing our axial flux generator design and the extra channels came in handy. We appreciate the ease of mounting and excellent support from Mr. Ellingson.
