ADJUSTING THE MACHINE FOR WELDING OF ALUMINIUM
For feeding the AL wire it is necessary to use roll with the “U” profile - see
paragraph OVERVIEW ROLLS WIRE FEED. To prevent problems with feeding
use wires with diameter. 1.0 mm of AIMg3 or AlMg. Wire of alloy Al99, 5 or AlSi5
are too soft and easily will cause problems with movement.
For the aluminium welding it is also necessary to provide the torch tefl. liner and
special current nipple. We do not recommend you to use the torch longer than 3
m. Great attention must be paid to adjust the contact power of rolls – it must not
be too high, otherwise there is a deformation of the wire.
As a protective atmosphere is necessary to use argon.
