Our factory (Shanghai OUPASI electric appliances) is equipped with a Fully Automatic Wire Threading, Resistance Measurement, and Spot Welding Integrated Machine, streamlining three core production steps into one continuous process.

This system automatically inserts resistance wires into magnesium oxide-filled tubes, instantly measures resistance values for precision control, and performs high-speed spot welding to secure terminal pins.

Key features of our production capability:

High efficiency – threading, testing, and welding completed in seconds

Real-time resistance monitoring – ensures product consistency

Stable spot welding – clean welds without damaging resistance wires

PLC-controlled – quick adjustment for different heater specifications

With this integrated equipment, we reduce manual handling, improve quality stability, and increase output per shift. Ideal for water heater tubes, oven heating elements, and industrial electric heating tubes.
