Safety Messages

2.1

Using the Correct Connection Terminal

Use the appropriate connection terminal that is compatible with the
fitting type used. Be sure the contact is firmly established and do not
use connection terminals or terminal adapters that are burnt or not
designed for the intended use.
2.2

Improper Use of the Welding and Power Supply Cables

Do not carry the product by its cables and do not pull the power cord
to unplug the unit from the socket. Protect the cables against heat,
oil, and cutting edges.
2.3

Securing the Fitting and the Joint

Use positioner clamps or a vice to secure the fitting and the joint
to be made before welding. The fitting manufacturer's installation
instructions, local and national regulations have to be respected in
all cases.
A welding process must never be repeated with the same fitting, since
this may cause parts under power to be accessible to the touch.
