2 INTRODUCTION
The EWT 1000 welding equipment is designed for Submerged Arc Welding (SAW) and
GMAW (MIG/MAG) welding of butt and fillet joints.
All other applications are prohibited.
The equipment is intended for use in combination with EAC10 and ESAB digital power
sources LAFxxx1, TAFxxx1, or Aristo 1000 and also through the analog interface LAF635
and LAF1000.
The EAC10 also supports analog-controlled power sources from other suppliers; see
chapter "Connecting to a compatible DC analog power source" for more information about
the interface.
2.1 Welding method
2.1.1 Definitions
SAW The weld bead is protected by a covering of flux during the
welding.
GMAW (MIG/MAG) welding The weld bead is protected by shielding gas during welding.
Twin wire welding Welding with two wires in one torch.
Flat fillet welding Welding in the downhand position, on the top side of the joint.
2.1.2 Submerged Arc Welding (SAW)
Use EWH 1000 or EWH 1000 twin welding equipment for Submerged Arc Welding.
EWH1000 permits loads of up to 1000A (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 an even wire
feed without risk of deformation of the welding wire due to high feed pressure.
2.1.3 GMAW (MIG/MAG) welding
For GMAW (MIG/MAG) welding use welding equipment EWH 600 gmaw.
EWH 600 gmaw consists of a GMAW torch and gas shielding equipment.
The welding head is water cooled. The cooling water is supplied by hoses from connections
intended for the purpose.
2.2 Horizontal welding
The product described in this manual is designed for horizontal welding. The welding tractor
can be used for flat fillet welding when welding a tilted fillet joint with the optional flat fillet
welding kit.
NOTE!
Do not use EWT1000 when welding on inclined planes.
Avoid welding on surfaces with a slope of greater than 3° (>6in/10ft/ >5cm/m) due to risk
of weld defects caused by the large amount of melted metal in the weld pool.
