1. GENERAL INFORMATION
1.1. Application
The LIZARD is a welding carriage designed to produce continuous or intermittent butt
and fillet welds using MIG/MAG torches with the handle diameter of 16–22 mm (0.63–
0.87’’). The carriage is fixed by permanent magnets and can work in the following
welding positions: PA/1F/1G, PB/2F, PC/2G, PD/4F, and PE/4G.
Accessories allow, for instance, welding with oscillation, using torches with the
handle diameter larger than 22 mm, two torches simultaneously, guiding the carriage
along outside edges, lap joints and templates, walls low or with holes, and on ceilings,
pipes, and tanks.

1.3. Design
The LIZARD welding carriage consists of a chassis, a drive system, a controller,
a cross slide, two guide arms, a cable anchor, and a torch holder. The drive system
contains a gear-motor that drives four rubber wheels.
Permanent magnets fitted at the carriage bottom ensure proper clamping to
ferromagnetic surfaces. The cross slide allows for precise control of the torch holder
position in both the horizontal and vertical axis, and connecting the arc ignition cable
will enable the carriage to ignite an arc when selecting a travel direction.

2. SAFETY PRECAUTIONS
1. Before beginning, read this Operator’s Manual and complete proper occupational
safety and health training.
2. Use the carriage only in applications specified in this Operator’s Manual.
3. The carriage must be complete and all parts must be genuine and fully operational.
4. The specifications of the power source must conform to those specified on the
ratingplate.
5. Plug the carriage into a properly grounded power source.
6. Never carry the carriage by the cords or the arc ignition cable and never pull them
as this may damage them and result in electric shock.
7. Untrained bystanders must not be present near the carriage.
8. Before beginning, make sure that the correct is the condition of the carriage, power
source, cords, arc ignition cable, plugs, control panel, and wheels.
9. Keep the carriage dry. Exposure to rain, snow, or frost is prohibited.
10. Keep the work area well lit, clean, and free of obstacles.
11. Never use near flammable liquids or gases, or in explosive environments.
12. Make sure that the rubber of the wheels is clean and not damaged.
13. Never disassemble the cover of the wheels.
14. Remove objects attracted to the chassis by the magnet.
15. Transport and position the carriage using the carrying handle and only when the
magnet ON/OFF lever is set to the position ‘O’.
16. Position the carriage on the ferromagnetic workpiece in such a way that the
wheels are in contact with the surface and there is no contact between the
surface and the chassis.
17. Do not stay below the carriage placed at heights.
18. Plug the cords and the arc ignition cable only when the power switch is set to the
position ‘O’.
19. Keep the sockets clean. Do not use compressed air for cleaning.
20. Install only MIG/MAG torches with the handle diameter corresponding to the
torch holder in use.
21. Position the torch not more than 80 mm (3.15’’) outward from the left or right side
of the carriage.

22. Keep the torch cables from coming in contact with the surface. They must be
suspended to reduce the load of the carriage. Use only cables whose weight is
not more than 12 kg (27 lbs) for horizontal work and 8 kg (18 lbs) for vertical work.
23. Operating on curvatures with a convex or concave radius less than 1500 mm (5 ft)
is prohibited.
24. When operating at heights, use a safety line to protect the carriage from dropping.
25. Always use eye protection (helmet, shield, and screen), hearing protection, gloves,
and protective clothing during operation. Do not wear loose clothing.
26. Before every use, inspect the carriage to ensure it is not damaged. Check whether
any part is cracked or improperly fitted. Make sure to maintain proper conditions
that may affect the operation of the carriage.
27. Never try to manually stop the motion of the carriage. To stop, set the travel
direction switch to the position ‘O’.
28. Maintain only when the carriage is unplugged from the power source.
29. Repair only in a service center appointed by the seller.
30. If the carriage falls from any height, is wet, or has any other damage that could
affect the technical state of the carriage, stop the operation and immediately
send the carriage to the service center for inspection and repair.
31. Never leave the carriage unattended during operation.
32. Remove from the worksite and store in a secure and dry location when not in use.

3. STARTUP AND OPERATION
3.1. Preparing
Use the carrying handle to transport the carriage to the worksite. Then, set to the
position ‘O’ all the switches (power, travel direction, and arc ignition switch) and the
magnet lever.

Connect the carriage to the power source, insert the torch into the torch holder,
and then secure it with the knob. Next, insert the torch cable into the cable anchor,
secure it with the knobs, and then fix the anchor in the required position using
the lever.

3.2. Connecting to welding circuits
The carriage can control two torches using the arc ignition cable plugged into the arc
ignition socket. To do this, connect any blue-jacketed wire to any terminal of the welding
circuit, and then connect the second blue-jacketed wire to the second terminal of the
same circuit, according to the diagram shown in Fig. 4. To control the second torch,
connect the green-jacketed wires to the terminals of the second welding circuit.
Fig. 4. Connecting the arc ignition cable to welding circuits
To check whether the arc ignition cable is connected correctly, power the carriage
by setting the power switch to the position ‘I’, and set the arc ignition switch to the
position TEST, which should enable the arc for a while.
