This program runs the advanced T.MAP RapiDeep process for ECOspark wire, 1.2 mm diameter, with M21 shielding gas. The manufacturer lists a more stable arc, less heat and fewer weld defects for RapiDeep.
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. TERRA NX 400/500 MSE and URANOS NX 2700 PMC and MTE are not listed for RapiDeep. 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 RapiDeep differ from ArcDrive?
ArcDrive is standard synergic welding with short and spray arc. RapiDeep is a T.MAP process: per the price list faster welding, better penetration and a more concentrated arc with less heat. ArcDrive for this set-up: ArcDrive 1.2 mm, gas M21 (79.S1.27699).
Can I use this program with a different gas?
No: the curves are made for M21. For M20 choose a separate program: RapiDeep 1.2 mm, gas M20 (79.RD.27999).
