INTRODUCTION

2.1

General

The A6TF F2 automatic welding machine, with two welding heads, is mounted on
a self-propelled trolley and is designed for submerged-arc welding of butt welds.
All other uses are prohibited
The position of welding head can be set horizontally and vertically with the linear
slides. Angular movement is adjusted with the angular slide.
The automatic welding machine is intended for use in combination with the PEK and
ESAB's welding power sources LAF or TAF.

Welding method

2.2.1 Submerged-arc welding
The weld bead is protected by a cover of flux during the welding.
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 wire welding . 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.
S
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 boxes 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 automatic welding machine is designed for horizontal welding.
A6TF F2 is not to be used for welding on inclined planes.
