High Frequency Inverter Spot Welding Power Supply - HF2

Product catalog summary

Overview: The HF2 and HF2S are high-frequency inverter welders designed for precision joining of small parts. Operating at 2 KHz, these welders offer high-speed digital feedback to control weld current, voltage, or power, ensuring consistent and repeatable welding. They are known for extending electrode life significantly and include a selectable weld energy limiting feature for high nugget quality.

Key Features:

Constant current, voltage, or power control modes.
High weld repetition rates suitable for spot, braze, and seam welding applications.
Graphical and alpha-numeric user interface with I/O communication ports for factory integration.
Optional built-in Weld Sentry for sophisticated weld data gathering and SPC computations.

Technical Specifications:

Control System: 2 KHz PWM inverter with feedback every 250 microseconds.
Line Voltage: Three-phase, 208, 230, 380, or 460 VAC ±13%, 50/60 Hz.
