Product Description
HFTR-45000 Servo Capacitor Discharge Spot Welding Machine
Product Overview
The HFTR-45000 utilizes stored electrical energy for resistance welding instead of conventional continuous welding power supplies. Energy discharges through the welding circuit when electrodes contact the workpiece, generating concentrated heat precisely at the welding point.
This energy-storage welding principle makes the machine ideal for applications requiring high instantaneous welding currents. Configured as a servo welding machine, the HFTR-45000 provides controlled electrode movement and repeatable welding conditions for precision applications.
The machine supports both spot welding and projection welding across various ferrous and non-ferrous materials.

Servo Capacitor Discharge Welding Process
Capacitor discharge welding systems store electrical energy before the welding cycle begins. During welding, this stored energy releases through the welding circuit, concentrating at the electrode-workpiece contact area.
The complete welding sequence includes:
- Energy storage
- Workpiece positioning
- Electrode approach
- Electrode pressure application
- Energy discharge
- Weld formation
- Holding period
- Electrode release
For projection welding, the projection on nuts, bolts, or metal components concentrates welding current and mechanical force at defined locations. The servo system adds precise mechanical movement control, with motion and force configurations tailored to specific workpiece and production requirements.

Material thickness, electrode configuration, welding position, and required joint strength should be evaluated during equipment selection.
Automotive Welding Applications
Automotive manufacturing utilizes high-strength steel, hot-formed steel, and galvanized sheet for structural and body components, often requiring carefully controlled resistance welding conditions.
High-Strength Steel: Used where higher material strength is required. Welding conditions should be established according to specific steel grade and component thickness.
Hot-Formed Steel: Used in automotive structural components. Joint structure, material condition, and electrode access must be considered during welding process development.
Galvanized Sheet: Zinc coating changes electrode-workpiece contact conditions. Electrode condition and welding parameters require careful consideration during process development.
Nut and Bolt Projection Welding: Projection geometry concentrates current and pressure at intended welding locations, making fixture positioning and electrode alignment critical for production consistency.
