This PulseDrive program sets the machine up for pulsed arc welding with G3/4 Si1 (ER70S-6) class wires, 0.9 mm, with M21 shielding gas. It provides pulsed arc and double pulse, which means less spatter and better pool control.
What it is for
The program holds synergic curves for this one combination of wire, diameter and gas. You change wire feed speed or plate thickness and the machine sets voltage and arc shape itself. The program is meant for unalloyed and low-alloy steels, which covers most structural work. M21 is the most widely used mixture for structural steels.

FAQ
Which machine can run this program?
Any machine on the list above. You buy the program for one specific machine: give its model and serial number with your order. Installation (service visit or manufacturer update) is agreed after the order.
How does PulseDrive differ from ArcDrive?
ArcDrive means short and spray arc without pulse. PulseDrive gives pulsed arc and double pulse: less spatter and easier pool control. ArcDrive for this set-up: ArcDrive 0.9 mm, gas M21 (79.S1.149).
Does it suit wire from any manufacturer?
Yes, if the wire belongs to the G3/4 Si1 (ER70S-6) class, which you can check on the spool label. If you weld with Union K 52, choose the program tuned to it: PulseDrive Union K 52 0.9 mm, gas M21 (79.P1.14995).
