1000 A IGBT DC Power Supply in the Welding Workshop of Baoti Equipment, Baoji, Shaanxi

Industry: Plasma welding & automated welding equipment  |  Site: welding workshop of Baoti Equipment, Baoji, Shaanxi  |  Product: 1000 A IGBT DC power supply

Kulun Electric’s 1000 A IGBT DC power supply is applied in the welding workshop of Baoti Equipment in Baoji, Shaanxi, mainly providing stable DC power for plasma welding systems. For plasma welding requirements of constant current output, wide parameter adjustment, arc starting and arc stability, safety protection and automation integration, the supply uses IGBT high-frequency inverter technology to meet current stability and control interface needs across different welding conditions.

1. Project Overview

2. Application Background

Plasma arc welding is a welding process with high requirements on power source output characteristics. Output current stability, arc starting success rate, arc stability and parameter adjustment accuracy directly affect welding quality, efficiency and the operating stability of automated equipment.

In the Baoti Equipment welding workshop, the plasma welding system needs a DC supply that adapts to different materials, thicknesses and process parameters. Beyond 1000 A-class current output, the supply must provide constant current control, wide-range adjustment, protection functions and automation interfaces.

3. Requirements & Technical Challenges

For this application, the heating and power control system had to address the following points:

• High constant current requirement: When arc length or workpiece surface condition changes, the supply must keep output stable, reducing current fluctuation effects on weld quality.
• Wide parameter adjustment range: Plasma welding covers different materials and thicknesses, requiring wide current and voltage adjustment ranges.
• Reliable arc starting and stability: Stable arc starting and arc keeping are needed at welding start and during continuous welding.
• Complete safety protection: Overcurrent, overvoltage, undervoltage and overheating protection must cut output and alarm promptly on abnormality.
• Automation integration: Welding equipment usually links to control systems; the supply must provide analog, digital or communication interfaces.
