This ArcDrive program sets up the machine to weld with ECOspark wire, 1.0 mm, with M20 shielding gas. It covers short arc and spray arc, in manual and synergic mode.
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. Typical work: steel structures, frames, tanks and machine parts in unalloyed and low-alloy steel.

FAQ
Will this program work on my machine?
Yes, as long as your machine is in the selection 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 1.0 mm, gas M20 (79.RD.27899).
Can I use this program with a different gas?
No: the curves are made for M20. For M21 choose a separate program: ArcDrive 1.0 mm, gas M21 (79.S1.27599).
