Welding processes, procedures and welding charac-
teristics for MIG/MAG welding

General

TPSi power sources contain a selection of welding processes, procedures and welding
characteristics that enable a wide range of materials to be processed in the most effective
way.
Welding charac- When selecting the filler metal, various process-optimised welding characteristics are
teristics available depending on the welding process and shielding gas combination.
The supplementary label for the welding process provides information about certain prop-
erties and the use of the welding characteristic:
Special welding characteristic properties
arc blow
arcing
braze
braze+
cladding
dynamic
galvanized
gap bridging
multi arc
pipe
root
universal
TWIN
Mixed process characteristics
mix
PCS
28
Characteristics with improved arc break properties by deflecting the
external magnetic fields
Characteristics for a special type of hardfacing on a wet or dry surface
(e.g. grinding rollers in the sugar and ethanol industries)
Characteristics for brazing processes (high brazing speed, reliable
wetting and good flow of braze material)
Optimized characteristics for bracing processes with special "Braze+"
gas nozzle (narrow gas nozzle opening, high shielding gas flow rate)
Characteristics for cladding with low penetration, low dilution and
wide weld seam flow for improved wetting
Characteristics for high welding speeds with concentrated arc
Characteristics for galvanised sheet surfaces (low zinc pore risk, re-
duced zinc melting loss)
Characteristics with very low heat input for optimum gap-bridging abil-
ity
Characteristics for components being welding by several interfering
arcs
Characteristics for pipe applications and positional welding on narrow
gap applications
Characteristics for root passes with powerful arc
Characteristics for conventional welding tasks
Synchronised characteristics for two wire electrodes in a single weld
pool (TANDEM welding process)
Characteristics with process switch between pulsed and dip transfer
arc
Specifically for welding vertical-up seams with cyclic change between
a hot and cold supporting process phase.
Pulse Controlled Spray Arc
Direct transition from the concentrated pulsed arc to a short spray arc.
The advantages of pulsed and standard arcs combined in a single
characteristic.
