This PulseDrive program sets the machine up for pulsed arc welding with ECOspark wire, 1.0 mm, with M20 shielding gas. Pulsed arc and double pulse make thin sheet and positional welds easier.
What it is for
Each program covers one combination: wire, diameter, gas. You enter wire speed or material thickness and the machine selects voltage and arc shape. Use it for unalloyed and low-alloy steels in the workshop and in production.

FAQ
Which machine can run this program?
Any machine on the list above. TERRA NX 320/400 SMC SteelDrive and TERRA NX 400/500 MSE are not listed for PulseDrive in the selection guide. 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 1.0 mm, gas M20 (79.S1.27899).
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) 1.0 mm, gas M20 (79.P1.013).
