General

General safety regulations for the handling of the equipment appear from
page 64. Read through before you start using the equipment!
Select wire type and shielding gas so that the weld material is as close as
S
possible to the analysis of the base material. Select wire size and welding data in
accordance with the values recommended by the consumables supplier.
Thorough joint preparation is necessary to achieve a good weld result.
S
NOTE! The width of the joint gap must be uniform.
To minimise the risk of heat crack formation the width of the weld must be
S
greater than the penetration depth.
Always carry out a test weld with the same joint type and plate thickness as the
S
workpiece to be produced.
For control and adjustment of the welding head and welding power source, see
S
the instruction manual for the A2--A6 Process Controller.
For the replacement of wear parts, see table on page 77.
