SAFETY INSTRUCTIONS

Although the “MAGNETIC MOGGY” carriage is manufactured for safe and dependable operation, it
is impossible to anticipate those combinations of circumstances, which could result in an accident.
An operator of this equipment is cautioned to always practice "Safety First" during each phase of
operation, setup and maintenance.

Read and understand the whole Operation Manual (including the additional Technical Manual
complete with the supplementary GSP Control Manual, “GD-031”) before operating or performing
service of this equipment. Become familiar with the machines operation, applications and
limitations. Keep the operation manual in a clean and readily available location.

This equipment is normally used to automate / semi-automate welding or cutting processes. These
processes usually have any combination of the following; bright and hot arcs, flying sparks, fumes,
ultraviolet and infrared radiated energy, hot work-pieces, compressed gases, etc.. The onus is on
the operator of this equipment to know, understand and follow all the safety precautions associated
with the process being used.

A careless operator invites troubles, and failure to follow safety practices may cause serious injury
or even death. Important safety precautions are given in the following:

Electrical Shock Prevention

 Do not use this equipment in damp or wet locations.
 Do not expose this equipment to rain.
 Never carry this equipment by the cables or pull the cables to disconnect from the

receptacle.

 Keep all cables from heat, oil and sharp edges.
 Inspect all cables periodically and replace if damaged.
 Inspect the secureness of all cables periodically and repair if loose.
 Disconnect the power cord when not in use.
 Disconnect the power cord positively to prevent electrical shock before repair and service

of the equipment.

Bodily Injury Prevention

 Do not wear loose clothing, jewellery and loose, long hair, which may get caught into

automatic systems or moving parts.

 Keep lifting handle dry, clean and free from oil and grease.
 Do not operate this equipment if ill or drowsy from medication or fatigue.
 Always keep the “MAGNETIC MOGGY” clean and in good working order.
 Report any unsafe condition for immediate correction.

ALL THE SAFE PRACTICES AND PRECAUTIONS MAY NOT BE GIVEN IN WRITING. SOME

ARE BASED ON COMMON SENSE, BUT OTHERS MAY REQUIRE TECHNICAL

BACKGROUND TO EXPLAIN.

SAFETY INSTRUCTIONS

The following cautionary/warning label is attached to each “MOGGY” carriage:­The below label pictorially represents the following:

“Warning:­Read the manual before turning the unit on and before performing service.

Also, positively disconnect the unit from all power supplies before servicing!”

VISE-VERSA

READ THIS BEFORE OPERATING THE “MOGGY” CARRIAGE

Ensure that an adequate and well-maintained weld return path is provided with good electrical
contact. Failure to do so may result in the welding current passing through the carriage and
damaging the wiring and electrical components.

Important information regarding safety and operation of the “GSP” motor control used in the
“MOGGY” carriage is contained in a supplemental manual attached at the end of the Technical
Manual. It is equally important to read, understand and apply the information contained within the
manual. The manual (GD-031) has a title “Technical Information For The Gullco “GSP” Micro­Processor Based, 24 Volt DC Motor Control”, and it’s pages are numbered with a prefix of “T“.

Warranty will be void if genuine Gullco replacement parts are not used.

“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

Note: wheels not exactly as shown, for

illustrative purposes only

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...

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

SETUP

Once the “MAGNETIC MOGGY” has been assembled and installed, as detailed in the Technical
Manual, adjust the vertical and horizontal slides so that they are in the middle of their strokes.
Insert the welding gun or cutting torch, into the gun holder. Position the gun or torch to the desired
operating position. Then adjust the two guide roller assemblies so that when both guide wheels are
running along the vertical member of the work-piece to be welded (or a template, guide or fence if
no vertical member is available), the leading guide wheel is marginally less extended than the
trailing guide wheel. On a straight work-piece, the optimum amount of difference is approximately
1” [25.4mm]. This places the “MAGNETIC MOGGY” carriage at approximately 5º off parallel to the
work-piece, ensuring that as the “MAGNETIC MOGGY” travels along, it is always driving in towards
the vertical guide. This ensures that the gun/torch to joint distance is always maintained. Fine
positioning of the gun/torch to joint may then be performed with the horizontal and vertical slides.
