Possible uses, IMPORTANT! As a rule, the Pulsed / Pulsed arc combination can be used for all
area of applicati- welding applications.
on
However, Pulsed / Pulsed is particularly suitable for aluminium applications.
A "master identification signal" is outputted by the robot control. This signal
defines the leading power source.
Time-coordination of the two power sources:
The welding-current pulses of the trailing power source are placed exactly
between 2 welding-current pulses of the leading power source (180° phase
displacement).
This leads to:
- optimum metal transfer (one droplet of metal per welding-current pulse)
- minimum arc-blow effect in the pulsed arc
- the arcs do not influence one another
IMPORTANT! As both power sources work with the same pulse frequency,
there is only a limited difference in the wirefeed speeds in the case of
the "Pulsed / Pulsed" arc combination.
stable arc across the entire power range
reproducible process
good thermal input and high welding speed:
A higher power output is usually set on the leading wire electrode.
This leads to:
- targeted thermal input
- thorough fusion of the cold base metal
- exact root fusion
- the trailing wire electrode fills the weld-pool
- prolonged degasification time (= reduced sensitivity to porosity)
- high welding speed
