This ArcDrive program sets up the machine to weld with G3/4 Si1 (ER70S-6) class wires, 0.8 mm, with M20 shielding gas. You work in synergic or manual mode, with short arc or spray arc.
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. 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. 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.
Should I choose RapiDeep instead of ArcDrive?
If productivity matters to you, yes. RapiDeep is a T.MAP process: the price list credits it with faster welding, better penetration and less heat. The guide does not list it for TERRA NX 400/500 MSE or URANOS NX 2700. The same set-up in RapiDeep: RapiDeep 0.8 mm, gas M20 (79.RD.012).
Does it suit wire from any manufacturer?
Yes, if the wire belongs to the G3/4 Si1 (ER70S-6) class, which you can check on the spool label. If you weld with BÖHLER EMK 8, choose the program tuned to it: ArcDrive BÖHLER EMK 8 0.8 mm, gas M20 (79.S1.23599).
