OPERATION

General

General safety regulations for the handling of the equipment can be found on
page 64. Read through before you start using the equipment!
Select wire type and flux or shielding gas so that the weld material is as close as
S
possible to the analysis of the base metal. Select wire size and welding data in
accordance with the values recommended by the welding materials supplier.
Thorough preparation of the weld surfaces is necessary to achieve a good weld.
S
NOTE! The width of the weld 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 sheet thickness as the
S
production work piece.
For control and adjustment of the automatic welding machine and welding power
S
supply, see the instruction manual for the A2--A6 Process Controller (PEH).
For replacement of wear parts, see table on page 204.
