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-
teristics
When selecting the filler metal, various process-optimised welding characteristics are
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 Characteristics with improved arc break properties by deflecting the
external magnetic fields
arcing Characteristics for a special type of hardfacing on a wet or dry surface
(e.g. grinding rollers in the sugar and ethanol industries)
braze Characteristics for brazing processes (high brazing speed, reliable
wetting and good flow of braze material)
braze+ Optimized characteristics for bracing processes with special "Braze+"
gas nozzle (narrow gas nozzle opening, high shielding gas flow rate)
cladding Characteristics for cladding with low penetration, low dilution and
wide weld seam flow for improved wetting
dynamic Characteristics for high welding speeds with concentrated arc
galvanized Characteristics for galvanised sheet surfaces (low zinc pore risk, re-
duced zinc melting loss)
gap bridging Characteristics with very low heat input for optimum gap-bridging abil-
ity
multi arc Characteristics for components being welding by several interfering
arcs
pipe Characteristics for pipe applications and positional welding on narrow
gap applications
root Characteristics for root passes with powerful arc
universal Characteristics for conventional welding tasks
TWIN Synchronised characteristics for two wire electrodes in a single weld
pool (TANDEM welding process)
Mixed process characteristics
mix 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.
PCS 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.
