Precision Automated Welding & Cutting Motion Control System

The Bug-O MDS Linear Weaver Kit (240V) is a heavy-duty, modular drive system engineered for automated arc welding and cutting applications that demand precise, repeatable weld quality. Built by Bug-O Systems, a trusted name in portable welding automation, this kit combines a high-torque Master Drive Unit with a Linear Weaver and Weaver Control Module to deliver consistent oscillating weld patterns on straight or curved workpieces.

Key Features

• 240V Master Drive Unit – High-torque, low-inertia motor with a fail-safe brake for precise starts and stops, plus motor overload protection for reliable long-term operation
• Closed-Loop Control – Closed-loop speed and position control ensure repeatable, high-quality welds pass after pass
• Linear Weaver Attachment – Bolts directly onto the carriage to produce true linear oscillation, with adjustable weave width from 1/8" to 2" (3–50 mm)
• Weaver Control Module – Digital readout with dial controls for travel speed, weave amplitude, weld dwell (left/right), steering, and a Forward/Stop/Reverse switch
• Multiple Weld Patterns – Selectable modes including Run, Step, Tractor Stop on Dwell, and No Weave to match your application
• Modular & Upgradeable Design – Compatible with the full Bug-O Modular Drive System (MDS) lineup, allowing future expansion with additional carriages, rail, or accessories
• Rigid Rail & Magnetic Mounting – Includes rigid track sections and on/off magnetic mounts for fast setup on flat or curved steel surfaces
• Durable Industrial Build – Designed for demanding shop-floor and field welding environments; backed by a manufacturer warranty

Ideal Applications

This kit is well-suited for shipbuilding, pressure vessel fabrication, structural steel, pipe and tank welding, and any operation requiring automated weaving for wide-groove or multi-pass welds. The 240V configuration makes it a strong fit for facilities running higher-voltage single-phase power infrastructure.

Why Choose the Bug-O MDS Linear Weaver Kit?

By automating the weave pattern, this system reduces operator fatigue, improves weld consistency, and increases productivity compared to manual weaving techniques — all while maintaining tight control over bead width, travel speed, and dwell time.
