The A6TF F1/ A6TF F1 Twin automatic welding machines are designed for
Submerged-arc welding (SAW) of butt and fillet joints.
All other applications are prohibited.
They are intended for use in combination with the control box, PEK and ESAB's
welding power sources LAF or TAF .
2.2 Welding Method
2.2.1 Submerged Arc Welding (SAW)
S Submerged arc Light Duty.
Submerged arc light duty with a Ø 20 mm connector permits a load up to
800 A (100%).
S
Submerged-arc Heavy duty
Submerged-arc heavy duty, with a
∅
35 mm connector, which permits a load of
up to 1500 A.
This version can be equipped with feed rollers for single or twin wire welding
(twin-arc). A special knurled feed roller is available for flux-cored wire, which
guarantees even wire feed without the risk of deformation due to high feed pressure.
2.3 Definitions
