INSTRUCTIONS FOR WELDING AND BLOW TORCH WORK ON THE EXTERNAL STRUCTURE
Ensure that there are no hydraulic or electrolyte leaks on the platform.
When welding, work in the opposite direction from the control console to avoid sparks damaging it .
-
Any welding and cutting (blow torch) work from the basket on a building’s metallic structures requires the following precautions to be
taken:
A - WITH ELECTRIC WELDING EQUIPMENT
- It is essential that the machine has a discharge braid connecting the platform’s chassis to the ground.
- It is also essential that the external structure to be welded is connected to the earth. If the above conditions are observed, the platform
can, in this case, be in contact with the structure or the elements to be welded without damaging the electronic components.
- The power supply to the welding equipment must be via an earthed socked and any extension required just also be earthed.
- In all cases, ensure that there are no electrical arcs in the basket or on the platform (contact between the brazing rod or the torch and the
welding equipment’s earth). To ensure this, at any time the welding equipment’s earth must not be positioned on the platform’s basket
but instead only as close as possible to the element to be welded.
- Switch off the welding equipment before disconnecting the earth clamp from the element or elements to be welded.
B - WITH A BLOW TORCH
- Attach the blow torch’s bottles to the basket’s handrails.

- Do not set the blow torch down on the lip of the basket while it is still operating or point it towards the control console or its power
cables.
