Welding Equipment
Wire feed system
The A314E/A324E-L wire feed system is a new
generation of wire feeder for ABB welding robots,
based on a well-proven basic concept.The main
feature of this new wire feed system is the very
wide speed range, from 0.5 – 30 m/min, which is
extended from the previous version.The very low
speed capability gives maximum control during
weld starts and excellent arc characteristics when
welding at low wire feed speeds as well as high
performance, high speed welding all the way up
to 30 m/min.This is thanks to the advanced
electronic precision control system.
The MIG/MAG process
Several different MIG/MAG process modes are
used in a robot welding system i.e. short arc,
spray arc, pulsed arc and rapid processing.The
key requirement for a stable arc, irrespective of
process mode, is a constant and reliable wire feed.
The performance of any power source and robot
system can be ruined if the wire feed is unstable.
The A314E/A324E-L wire feed system satisfies
these requirements giving you reliable, high
performance welding.

Welding Equipment
Integrated with the robot
The wire feeder is mounted on the upper arm of
the robot, which gives only a short distance between
the wire feeder and the welding gun, a necessity
for stable wire feeding.Weld starts are particularly
sensitive to long feed lengths due to the flexibility
of the wire in the liner.
The signal cables to the feeder are integrated
into the robot, simplifying the cable management
to achieve maximum movement of the robot in any
station configuration.
Programming
The programming of the complete robot welding
station is performed from the programming unit.
This includes all the welding parameters such as
voltage, wire feed speed and crater fill data.
The wire feeder is only one component in ABB’s
comprehensive range of equipment.Together these
components ensure high quality robotic welding.
Technical data
Wire feed speed range 0.5 – 30 m/min
Wire diameters (standard) 1.0 and 1.2 mm
Safe and user-friendly design
The wire feed unit, together with the sensors, valves,
relays etc. is enclosed in a protective case to minimise
contamination of the feeder, wire and electrics from
damaging abrasive dust and also to protect the user
from exposed parts of the welding circuit. Push
buttons mounted on the front of the case provide
easy access for manual operations such as wire feed
and safety reset.The status of water flow, gas flow
and collision sensor are shown on the robot teach
pendant, making it quick and easy to trace the
source of errors.
The wire feed unit is equipped with four driven
feed rolls powered by a strong electrical encoder
driven motor with tacho supervision to ensure accu-
rate and reliable wire feeding.The control system is
based on computerised switching technology to give
rapid acceleration and deceleration of the wire feed,
and important factor during arc starts and stops.
Rollers for other diameters and for different types of
wire are available as options.
