5.7 USE CHEMICALLY INERT PIPES
Never perform welding on pipes that contain (or previously
contained) substances which, combined with heat, can
produce gases that are explosive or dangerous to human
health.
5.8 PERSONAL PROTECTION
Wear insulating footwear and gloves.
5.9 BE CAREFUL WITH THE CABLES
•
Never disconnect the plug from the power socket
by tugging on the power cable;
•
Never detach the pins from the fitting by tugging
on their power cables;
•
Never move the equipment by dragging it along
by its power cables.
•
Do not touch directly exposed/worn out
terminals/connectors
5.10 PREVENT OVERVOLTAGE
Use stabilized generators only. Voltage spikes and
overvoltage may damage the equipment.
5.11 FIRE OR EXPLOSION
This welding equipment must not be used in areas where
there is any risk of fire or explosion. It is compulsory in such
conditions to use specifically designed and constructed
equipment.
5.12 DISCONNECT POWER PLUG AFTER WELDING
On completion of the welding operation, always
remember to disconnect the plug from the mains /power
socket.
6. General welding criteria
The quality of the joint depends on your careful compliance with the following
recommendations.
6.1 HANDLING THE PIPES AND COUPLINGS:
During welding, the pipes and couplings must be at near-ambient
temperature, as detected by the welder’s temperature probe. They
must consequently be protected from direct sunlight both before
and during welding, since they could otherwise become much
warmer than the ambient temperature, with a consequent
negative effect on the electro-melting process (i.e. excessive
melting of the pipe and coupling). In the case of excessively high
temperatures, move the pipes and couplings to a cool, shady place and wait for their
temperature to return to near-ambient values.
