2 INTRODUCTION
2.1 General
The A2TFJ1/A2TFJ1Twin automatic welding equipment is designed for Submerged Arc
Welding (SAW) of butt and fillet joints.
The A2TGJ1/A2TGJ14WD automatic welding equipment is designed for MIG/MAG
welding of butt and fillet joints.
All other applications are prohibited.
Intended for use in combination with PEK and ESAB welding power sources LAF, TAF or
Aristo1000.
NOTE!
Aristo1000 only together with PEK with serial no. 747-xxx-xxxx or later.
2.2 Welding method
2.2.1 Submerged Arc Welding (SAW)
Use A2TFJ1/A2TFJ1Twin automatic welding equipment for Submerged Arc Welding.
• Submerged Arc Light duty
Submerged Arc Light duty with a Ø20mm connector permits a load up to 800A
(100%).
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.
2.2.2 MIG/MAG welding
For MIG/MAG welding use either automatic welding equipment A2TGJ1 or A2TGJ14WD.
A2TGJ14WD consists of a four wheel drive wire feed unit.
The welding head is water-cooled. The cooling water is supplied by hoses from connections
intended for the purpose.
2.3 Definitions
SAW The weld bead is protected by a cover of flux during the welding.
SAW Light duty Permits welding with lower current load and thin wire.
MIG/MAG welding The weld bead is protected by shielding gas during welding.
Twin-arc welding Welding with two wires in one welding head.
2.4 Horizontal welding
The products described in this manual are designed for horizontal welding.
NOTE!
Do not use A2 Multitrac when welding on inclined planes.
