PulseDrive program for Union K 56 wire, 1.0 mm, with M21 shielding gas. It provides pulsed arc and double pulse, which means less spatter and better pool control.
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. Use it for unalloyed and low-alloy steels in the workshop and in production. M21 is the most widely used mixture for structural steels.

FAQ
Can I add this program to my TERRA NX or URANOS NX?
Yes, if your model is 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. 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 1.0 mm, gas M21 (79.S1.00894).
Can I use this program with a different gas?
No: the curves are made for M21. For M20 choose a separate program: PulseDrive 1.0 mm, gas M20 (79.P1.01394).
