This synergic ArcDrive program is set up for Union K 56 wire, 0.8 mm diameter, with M21 shielding gas. It covers short arc and spray arc, in manual and synergic mode.
What it is for
A program is a set of synergic curves for one wire, one diameter and one gas: you set wire speed or material thickness and the machine selects voltage and arc shape. Use it for unalloyed and low-alloy steels in the workshop and in production. M21 is the most widely used mixture for structural steels.

FAQ
Which machine can run this program?
Any machine on the 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 ArcDrive differ from PulseDrive?
ArcDrive welds with short and spray arc, without pulse. PulseDrive adds pulsed arc and double pulse, which helps on thin sheet and in position. The PulseDrive version of this program: PulseDrive 0.8 mm, gas M21 (79.P1.00794).
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 C1 choose a separate program: ArcDrive 0.8 mm, gas C1 (79.S1.00294).
