Point welding machines are divided into pedal welding machines, Working Principle of Extrusion Welding Machine, mid -frequency point welding machines, which are small categories of resistance welding machines. Working Principle of Extrusion Welding Machine is generally a industrial -frequency AC welding machine. It uses cylinder compressed air to compress the workpiece to achieve a type of welding machine. The controller has three modes: constant voltage, constant heat, and constant current.

Set the constant pressure mode according to the following details

1. Open the "power switch" on the right side of the controller to display the lights of the window.

2. Press the work/set key to switch to the set state

3. Press the "↑ ↓" key in the middle, press and press for 5 seconds to enter the "secondary menu"

4. Click the "↑ ↓" key until the parameter value appears.

5. Press "+ -" key to turn numbers into "4"

6. Press the "↑" key, select "AC00" status

7. Turn off the controller power switch and restart the switch

8. At this time, the concept of the controller in the "constant voltage state" is "V" (that is, the number 50 is 50V and the highest is 450V).
