This PulseDrive program sets the machine up for pulsed arc welding with BÖHLER EMK 4 Ultra wire, 1.2 mm, with M21 shielding gas. You get pulsed arc and double pulse, useful where the look of the weld face matters.
What it is for
A program is a set of synergic curves for one wire, one diameter and one gas: you set wire speed or material thickness and the machine selects voltage and arc shape. 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
Will this program work on my machine?
Yes, as long as your machine is in the selection 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 1.2 mm, gas M21 (79.S1.00992).
Can I use another ER70S-3 wire?
The curves are tuned to BÖHLER EMK 4 Ultra. Another wire may behave differently, so contact us and we will match a program to the wire you use.
