This PulseDrive program sets the machine up for pulsed arc welding with BÖHLER EMK 4 Ultra wire, 1.2 mm, with M20 shielding gas. Pulsed arc and double pulse make thin sheet and positional welds easier.
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. M20 contains less CO2 than M21, so the arc is calmer and produces less spatter.

FAQ
Will this program work on my machine?
Yes, as long as your machine is in the selection list above. Give the machine model and serial number with your order so we can confirm compatibility with its software. Whether our service installs it or it comes as a manufacturer update is settled 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 1.2 mm, gas M20 (79.S1.01492).
Can I use this program with a different gas?
No: the curves are made for M20. For M21 choose a separate program: PulseDrive 1.2 mm, gas M21 (79.P1.00992).
