Product Description

Hwashi AT-MF25K Gantry Multi-Spot Welder for Sheet Metal Stiffener

Product Overview

One Pass. Continuous Seam. Zero Leaks.

Introducing the Hwashi AT-MF25K Gantry Multi-Spot Welding Machine — engineered for high-volume production of sheet metal stiffeners, reinforcement ribs, and structural reinforcement profiles. Designed for elevator door panels, control cabinet enclosures, supermarket shelf boards, and industrial box panels. Built for manufacturers who demand precision, speed, and consistent weld quality across large production runs.

Product Description

The AT-MF25K is a gantry-style automatic multi-spot welding machine specifically engineered for reinforcing stiffener ribs on sheet metal components. Featuring a robust gantry structure with horizontally and vertically adjustable electrode spacing, this machine handles both single-row and multi-row stiffener welding with unmatched flexibility.

What sets the AT-MF25K apart is its servo-driven feeding and welding system — operators load the sheet metal once, and the machine automatically completes all weld points in a single clamping cycle. The MFDC (Medium Frequency Direct Current) inverter power supply delivers rapid welding cycles while preserving zinc coating integrity on galvanized sheets, ensuring weld spots remain color-consistent and free from burn-through or zinc spattering.

Trusted by leading manufacturers including Fast Elevator, the AT-MF25K is the go-to solution for elevator door panel production lines requiring high throughput and zero-defect welds.

Working Principle

The AT-MF25K employs MFDC (Medium Frequency Direct Current) spot welding technology operating at 1000Hz inverter frequency. The gantry structure provides rigid support for multiple welding transformers, while servo motors drive precise horizontal and vertical positioning of electrode heads. Weld parameters (current, time, pressure) are precisely controlled through the human-machine interface (HMI), allowing operators to set weld row count and spacing directly on the touchscreen.
