Equipment Overview

Intermediate Frequency Inverter DC Resistance Welding Control Power Supply is composed of single-phase or three-phase alternating current into pulsating direct current through a rectifier circuit, which is converted into an intermediate frequency square wave connected to a transformer through an inverter circuit composed of power switching devices, and then rectified into direct current with less pulsation after step-down to supply electrodes for welding workpieces. Inverters usually use current feedback pulse width modulation to obtain stable constant current output. The intermediate frequency inverter spot welding machine has superior performance and is suitable for welding thin metal parts with high thermal conductivity and fine workpieces.

IST inverter DC spot welding machine features

1. Induction load voltage, feedback control constant current, to achieve high-quality welding.

2. The power-on mode of PRE HEAT and MAIN HEAT is preheated before welding to ensure stable welding quality.

3. Maintain the continuity of energy density, short welding time, and reduce the deformation and discoloration of the base material. (Welding time is controlled in microsecond units, continuous output mode).

4. Easy to change from low current to high current, suitable for precision welding.

5. The upper and lower limits of the current can be set to simply judge whether the welding quality is good or not, which is suitable for welding automation instruments.

6. The welding current rises with the power-on time to ensure the welding result.
