6.1 HOW TO CHOOSE THE WIRE LINER fOR DIRECT AND EURO CONNECTION
TORCHES
Mainly we can have 2 types of wire liners: Steel wire liners and Teflon wire liners.
• The steel wire liners can be coated or not coated: the coated wire liners are used for air cooled torches;
the wire liners which are not coated are used for water cooled torches.
• The Teflon wire liners are suggested for the welding of Aluminium, as they allow a smooth feeding
of the wire.
