This PulseDrive program sets the machine up for pulsed arc welding with ECOspark wire, 1.2 mm, with M20 shielding gas. You get pulsed arc and double pulse, useful where the look of the weld face matters.
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. Typical work: steel structures, frames, tanks and machine parts in unalloyed and low-alloy steel.

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 1.2 mm, gas M20 (79.S1.27999).
Can I use another ER70S-6 wire?
The curves are tuned to ECOspark. For other brands of the same class the price list offers the Universal ARC line, here: PulseDrive G3/4 Si1 (ER70S-6) 1.2 mm, gas M20 (79.P1.014).
