Welding method

2.2.1

Submerged Arc Welding (SAW)

The weld bead is protected by a cover of flux during the welding.
• Submerged Arc Heavy duty
Submerged Arc Heavy duty with a Ø35 mm connector, permits a load of up to 1500 A.
This version can be equipped with feed rollers for single wire welding. A special knurled feed
roller is available for flux-cored wire, which guarantees even feed without the risk of
deformation due to high feed pressure.
• Tandem welding (Submerged Arc)
For tandem welding, a welding head of type A6SF is always used, which must be connected
to 2 welding power sources and 2 control units of type PEK.
The tandem welding head includes 2 single welding heads (A6SF), each with its own contact
tip. Each contact tip has a maximum rated load of 1500 A.
2.3

Horizontal welding

The products described in this manual are designed for horizontal welding.
NOTE!
Do not use A6 Mastertrac Tandem when welding on inclined planes.
