Frequently Asked Questions
?
What materials can the UN series welding machines process?
The UN series is specifically designed for welding low-carbon steel, aluminum, and copper. The welding diameter range varies depending on the specific model selected.
?
What is the input voltage requirement for these models?
All models in this series, including UN-25, UN-30, and UN-50, operate on a standard input voltage of 380V.
?
What does the 20% duty cycle indicate?
A 20% duty cycle means that within a 10-minute operating cycle, the machine can weld continuously for 2 minutes and must cool down for the remaining 8 minutes.
?
How do the input currents differ among the UN-25, UN-30, and UN-50 models?
The input current scales with the rated capacity: UN-25 requires 65.8A, UN-30 requires 78.9A, and the high-capacity UN-50 requires 131.6A.
?
Which model is best suited for welding thicker copper rods?
For copper welding, the UN-50 model is recommended as it supports a welding diameter range of 5-12 mm, compared to 4-8 mm for the UN-25 and 4-10 mm for the UN-30.
