ArcDrive program for Union K 56 wire, 0.8 mm, with M20 shielding gas. This is classic MIG/MAG without pulse: short arc at lower currents and spray arc at higher ones.
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
Can I add this program to my TERRA NX or URANOS NX?
Yes, if your model is 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. 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 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 M20 (79.P1.01294).
Can I use this program with a different gas?
No: the curves are made for M20. For C1 choose a separate program: ArcDrive 0.8 mm, gas C1 (79.S1.00294).
