This ArcDrive program sets up the machine to weld with BÖHLER EMK 4 Ultra wire, 1.2 mm, with C1 shielding gas. It covers short arc and spray arc, in manual and synergic mode.
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.

FAQ
Which machine can run this program?
Any machine on the list above. ArcDrive has the widest machine list: it also covers TERRA NX 320/400 SMC SteelDrive and TERRA NX 400/500 MSE. When ordering, give the model and serial number of the machine the program is for. Installation, by our service or as a manufacturer update, is agreed after the order.
How does ArcDrive differ from PulseDrive?
ArcDrive welds with short and spray arc, without pulse. PulseDrive adds pulsed arc and double pulse, which helps on thin sheet and in position.
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.
