Stiffener Welder
The Stiffener Welder automates dual-side welding for “I,” “T,” and “Angle” stiffeners, handling flange widths up to 12″ (300 mm) and heights from 3″ to 16″ (75–400 mm). Mounted on caster and guide wheels, it offers easy mobility and precise torch tracking with spring-loaded arms and spatter guards. Equipped with heavy-duty drive and top-brand wire feeders, it delivers reliable, efficient welding for a variety of applications.
Key Features
Dual-Side Welder for Maximum Efficiency
Weld both sides of a stiffener simultaneously, doubling your production rate and significantly reducing welding time.
Versatile Stiffener Compatibility
Weld “I”, “T”, and “Angle” stiffeners with flange widths from 0 to 12 inches (0–300 mm) and heights from 3 to 16 inches (75–400 mm).
High-Quality Components
Equipped with either the Lincoln Electric® Flex Feed® 84 or Miller® S-74 wire feeders—trusted names in industrial welding.
Advanced Torch Tracking System
Two floating, spring-loaded arms with “V” rollers and spatter guards follow the joint precisely, even over tack welds.
Heavy-Duty, Mobile Design
Four large caster wheels provide effortless mobility, while a rugged drive system ensures smooth, consistent travel along the workpiece.
Made in the USA
Proudly built in the United States using industrial-grade components for reliability and durability.
