A motor repair company in Southeast Asia was facing a challenge that many industrial maintenance workshops
know all too well.
Their business focused on repairing large electric motors, generators, and power distribution equipment. During
maintenance, damaged copper busbars, conductors, terminals, and electrical connectors often required rebuilding or
repair welding.
Although they had tried several welding materials, the results were not always satisfactory. Some welds showed
poor conductivity, while others developed porosity or cracks after service. In some cases, overheating occurred at the
repaired area, leading to additional downtime and expensive rework.

The company needed a more reliable solution.
A Simple Change That Made a Big Difference
After receiving a recommendation from an experienced welding engineer, the company decided to test ERCu
Copper Welding Wire.
The first application involved repairing a heavily worn copper busbar in an industrial power distribution system.
The welding team immediately noticed the difference:
• Stable arc performance
• Smooth wire feeding
• Excellent fusion with the copper base metal
• Minimal spatter
• Clean and attractive weld appearance
Most importantly, conductivity testing after welding showed excellent results.
The repaired busbar was returned to service and continued operating under high electrical loads without overheating
or failure.
Expanding the Use of ERCu
Encouraged by the successful repair, the company began using ERCu Copper Welding Wire in a wider range of
projects, including:
• Copper busbar repair and fabrication
• Electric motor winding restoration
• Transformer maintenance
• Generator component rebuilding
• Copper connector manufacturing
• Electrical terminal welding
• Industrial equipment maintenance



According to the workshop manager:
"The biggest benefit was confidence. We knew the repaired components would perform reliably in service. That
reduced callbacks, rework, and customer complaints."
Why ERCu Copper Welding Wire Works
