Waveform of speed short arc welding process
By eliminating the "globular" arc mode, which is characterized by heavy and sticky spatter and higher energy than the short a
speed short arc enables to:
Reduce the amount of distortions at high welding currents in the typical "globular" welding range
Reduce the amount of spatter compared to the globular mode
Achieve good weld appearance
reduce smoke emissions compared with the usual modes (up to 25% less)
Achieve good rounded penetration
Enable welding in all positions

NORMAL Pulsed MIG
Metal transfer in the arc takes place by detachment of droplets caused by current pulses. The microprocessor calculates all t
parameters for each wire speed, to ensure superior welding and striking results.
The advantages of pulsed Mig are :
☞ Reduced distortions at high welding currents in the customary "globular" welding and spray arc ranges
☞ Enables all welding positions
☞
Excellent fusion of stainless steel and aluminium wires
☞ Almost complete elimination of spatter and hence of finishing work
☞
good bead appearance
☞ Reduced smoke emissions compared with customary methods and even
