Frequently Asked Questions (FAQ)
What materials are the UN series butt welding machines suitable for?
The UN series butt welding machines are specifically designed to weld Low-Carbon Steel, Aluminum, and Copper rods or wires.
What are the differences in capacity and input current among the UN-25, UN-30, and UN-50 models?
The UN-25 has a rated capacity of 25KVA with an input current of 65.8A; the UN-30 has a capacity of 30KVA with an input current of 78.9A; and the UN-50 features a capacity of 50KVA with an input current of 131.6A. All models operate on a 380V input voltage.
What is the duty cycle of these welding machines?
All three models (UN-25, UN-30, and UN-50) have a standard rated duty cycle of 20%, ensuring stable performance for industrial batch processing.
What is the maximum welding diameter for copper on the UN-50 model?
For copper materials, the UN-50 model supports a welding diameter range of 5 mm to 12 mm.
How does material type affect the welding diameter range?
Welding capacity varies by material conductivity and hardness. For example, the UN-30 welds Low-Carbon Steel from 6-16 mm, Aluminum from 5-12 mm, and Copper from 4-10 mm. Please refer to the parameters table to choose the right model for your specific material dimensions.
