1. Stable machine structure upside and downside of electrodes apply the pressure mode with assistant stroke. The welding efficiency is much higher.
2. The transformer of welding machine adopts the special resistance welding machine, the silicon steel slice is featured of high magnetic: the inner water- cooled by force; stronger power and high duty ratio.
3. Controlled by micro-computer and can saved at most 16 sets of welding settings, which is quite convenient for different kinds of welding sheets.
4. Can widely used in nut, studs, traffic tools, household items, cars. And it can be welded low-carbon steel, stainless steel, coated steel, non-ferrous metal wire, sheet, pipe, etc.
Components of Welding Machine:
The fire door spot welding machine consists of a frame, a workpiece moving platform, a welding machine moving mechanism, upper and lower electrodes, a welding transformer, and a welding machine controller, PLC controller, air circuit system, cooling water circuit system and other components.
Pneumatic Transmission Mechanism:
When the fire door spot welding machine is used for welding, the lowering of the upper electrode and the pressing of the weldment are realized by the pneumatic transmission mechanism,the mechanism is composed of cylinder, piston, guide rod, sealing ring, sealing ring, etc.
Air Circuit System:
The air circuit system is composed of ball valve, air filter, pressure reducing valve, oil atomizer, electromagnetic air valve, cylinder, etc.
Install the workpiece: the rear positioning block and the right positioning block are used as the reference positioning block. To adjust, the motor zero point needs to be corrected. Other positioning blocks can be adjusted close to the workpiece. The side floating positioning block clamps the framework of the workpiece and the panel together to avoid the displacement of the welding spot. (The manual clamping screw fixes the workpiece on the side floating positioning block).
Welding: after the start (automatic) switch is pressed, the program automatically controls the action of the equipment to complete the product until the stop button is pressed.
Control System Functions
Specific functions are as follows:
1.The welding time: can be set to accurately control the welding time through IGBT, which provides necessary conditions for the consistency of welding.
2. The constant current function: can realize the constant current function through the control of IGBT, which solves the fundamental problem that ordinary energy storage welding cannot control the welding current.
3. Multiple discharge pulses: have three welding pulses: preheating, welding and tempering. The welding pulse can be cycled, and the number of cycles can be set to 99 at most.
4. Welding current display: the effective value and peak value of welding current can be displayed after welding.
