• Ideal for automatic horizontal fillet, lap and butt welding operations
  • Controls are available to perform continuous and/or stitch weld operations
  • Dual gun holder assembly is available for efficient simultaneous welding
  • Wheels on the standard Moggy can be reversed to allow the moggy to run on standard v-groove track
  • The magnetic moggy has a magnetic base that clings to the vertical member for out of position applications
MOGGY® Automated Trackless Welding Carriage

The Gullco MOGGY® friction drive travel carriage is designed to perform Horizontal Fillet Welding, Lap Welding and Butt Welding. It can be fitted with a Gullco Compact Oscillator to perform multi-pass welding. These operations can be performed on horizontal fillets with a minimum radius of 39 in. (1 meter) and up to a 30º incline. Following is a brief description of the Moggy and components that make up the system.

It is a lightweight, portable, four wheel friction drive travel carriage that can be used with or without track to automate welding operations. A speed potentiometer provides infinite speed selection within the 6 to 115 in/min (15.2 to 292.2 cm/min) range. The unit comes complete with adjustable guide rolls, travel limit switch assembly, vertical and horizontal slides providing 1 3/4" (44.4mm) adjustment and a semi-automatic gun holder. It is designed to run on a horizontal path against a vertical surface or a vertical path against a horizontal surface (Magnetic MOGGY®) to perform a fillet weld.

The Standard MOGGY® can be adapted for use on standard 6" (152.4mm) v-groove track by reversing the wheel assemblies. Safety is assured by using Gullco low voltage 24 volt DC highly advanced control power supply system that is available in 3 line voltage inputs ... 42, 110 and 230 volt AC 50/60 Hz.

Trackless Magnetic MOGGY® Trackless Welding Travel Carriage

"low cost, highly efficient automation of out-of-position fillet, lap and butt welding applications"

This Gullco MOGGY® is essentially the same as the Standard MOGGY® described inside this folder except it has a magnetic base and heavy duty urethane 0.875" (22.23 mm) wide wheels for continuous travel in the horizontal and vertical position.
