Dc Inverter Precision Steel Door Aluminum Stud Multi Head Spot
Welding Machine
Product Introduction
The multi head spot welding machine is mainly composed of machine
body, transformer, upper and lower projection welding platform
(special projection welding machine), upper and lower welding arm
body (special spot welding machine), gas circuit (pressurization)
system, water circuit (cooling) system, controller and manual
switch.

Advantages
1. The welding current is DC. When there are inductive/magnetic
materials in the secondary winding, the welding will not be
affected;
2. The body of the stationary spot welding machine is cast by the
thickened steel plate, and the body is stable.
3. The upper and lower electrodes are made of highly conductive
materials with auxiliary pressure, which has good welding effect
and high efficiency. The internal water cooling system can reduce
the welding temperature.
4. Spot welder can store up to 15 groups of welding modes, which
can meet the requirements of different workpieces.
Major Structure
Working Principle
The time control of "pressurization", "welding", "maintenance",
"rest" and other procedures in the process of welding workpiece is
completed by the time regulator in the spot welding controller. The
time required for each procedure and the size of welding current
(i.e., "welding specification") should be set in advance.
When the welding machine is welding, first place the workpiece
between the electrode of the welding tongs, then press the switch
manually, the "pressurization" program starts, the solenoid valve
acts, and the compressed air enters the cylinder of the welding
machine to make the electrode of the welding tongs act, and then
press the workpiece tightly; After an appropriate delay, the
"welding" procedure begins. At this time, the primary coil of the
welding transformer is connected to the power supply through the
triggered thyristor (whose conduction angle is controllable), and
the secondary welding current is generated to weld the workpiece;
After the "welding" procedure, the thyristor is turned off, the
transformer primary coil is powered off, and the welding machine
enters the "maintenance" procedure; After the pressure is
maintained for a period of time, the solenoid valve is
disconnected, the upper electrode releases the workpiece, and the
welding machine enters the "rest" procedure. At this time, a
welding cycle has been completed.
