This RapiDeep program runs the T.MAP process for Union K 52 wire, 0.8 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. The program is meant for unalloyed and low-alloy steels, which covers most structural work. A 0.8 mm wire works well on thin sheet and in position welding.

FAQ
Will this program work on my machine?
Yes, as long as your machine is in the selection list above. 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 0.8 mm, gas M21 (79.S1.00795).
Can I use this program with a different gas?
No: the curves are made for M21. M21 is the most widely used mixture for structural steels. For M20 choose a separate program: RapiDeep 0.8 mm, gas M20 (79.RD.01295).
