“MOGGY” PORTABLE FRICTION DRIVE TRAVEL CARRIAGE
This manual covers the operating instructions of the following “MAGNETIC MOGGY” travel
carriages;- GM-03-300,
GM-03-350.
GENERAL DESCRIPTION
The Gullco “ MAGNETIC MOGGY” is a portable, friction drive travel carriage, designed with multiple
functionality in mind. It is an electrically powered self propelled carriage that travels in forward and
reverse directions at precisely controlled speeds. It consists of a 24 VDC permanent magnet gear
motor which engages with the drive axle through a pair of bevel gears. The drive and driven axles
are connected through a toothed timing belt arrangement which allows both axles to impart a
tractive effort through the four rubber tired, friction drive wheels. Fine adjustment horizontal and
vertical positioning slides as well as a fully adjustable gun/torch holder positioning assembly, are
used to attach the welding gun or cutting torch, to the “MAGNETIC MOGGY” carriage. Adjustable
guide roller assemblies enable the “MOGGY” carriage to maintain a set distance from a vertical
member (usually the vertical member of a fillet joint). The unit is equipped with a raised carrying
handle for lifting, as well as for hanging when in storage. Safety is greatly enhanced by the use of
Gullco’s low voltage (24 VDC), highly advanced control and power supply system that is available in
three line voltage inputs...42, 115 and 230 VAC, single phase, 50/60 Hz., or alternately, any
unregulated 24 V power supply at 30 watts of power. The microprocessor motor control offers
operator interface of forward, reverse, infinitely variable speed, weld enable and disable functions
and, depending on the model, various welding/stitch welding parameters. An L.E.D. display
indicates different modes and status of operation as well as showing the travel speed in either
inches per minute or centimetres per minute. An end of travel limit switch and actuating rod is used
to stop the “MAGNETIC MOGGY” and welding/cutting cycle when activated.
INTENDED / FORESEEN USAGE
The Gullco “MAGNETIC MOGGY” is
intended to automate and improve the
quality of welding and cutting operations
by carrying the welding gun or cutting
torch, at precisely controlled speeds, along
the path of the joint as well as providing
the interface between the welding/cutting
motion and the arc start and stop signal(s).
The “MAGNETIC MOGGY” is normally
guided by adjustable guide wheels which
are used to keep a set distance from the
joint/weld path. The “MAGNETIC
MOGGY” carriage is flexible enough to
allow it to be easily configured for
horizontal lap, butt and fillet weld joints as
well as a variety of cutting processes. The
GM-03-350 model provides continuous
mode welding/cutting and the GM-03-300
models also offer accurate distance stitch weld functionality, regardless of travel speed adjustment.
Using the Gullco “MAGNETIC MOGGY” travel carriage system will add accuracy and uniformity to
welding/cutting operations while increasing productivity. Typical applications include shipbuilding,
offshore construction, steel fabrication industries, etc...
