Stainless Tube Mill
Using two MA-40 magnetic arc controls, two MP-4 probes, and three AVC-5 arc length control systems, the TIG arc is compressed and oscillated to reduce arc drag and porosity. Increased penetration, consistent seam fusion and very high travel speeds were achieved using the first arc for preheating (oscillating the arc longitudinally) and the second arc for compressing the arc for full penetration welding.

V-Prep Joint on Steel Flange
An MP-1 magnetic probe is used in conjunction with precision wire feed to create a wide weave patterned weld bead, which has equally deep penetration on both sides. The magnetic arc oscillator eliminated the need for a mechanical oscillator.
