ArcDrive program for G3/4 Si1 (ER70S-6) class wires, 0.8 mm, with M21 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
Will this program work on my machine?
Yes, as long as your machine is in the selection list above. 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 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. The PulseDrive version of this program: PulseDrive 0.8 mm, gas M21 (79.P1.007).
Can I use this program with a different gas?
No: the curves are made for M21. M21 is the most widely used mixture for structural steels. For C1 choose a separate program: ArcDrive 0.8 mm, gas C1 (79.S1.002).
