This RapiDeep program runs the T.MAP process for diamondspark GUARD 420 MC wire, 1.2 mm, with M21 shielding gas. The Böhler Welding price list credits RapiDeep with faster welding, better penetration and a more concentrated 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
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 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.S1.28199).
Can I use this program with a different wire?
The curves are tuned to diamondspark GUARD 420 MC. Another wire may behave differently, so contact us and we will match a program to the wire you use.
