Magnetic Arc Control: Magnetic Probes

All probes include simple, secure mounting provisions and can attach to most welding torches in minutes. Water-cooling hoses (where required) and probe cables are part of each probe assembly. See the controller/probe compatibility chart for system details.

MP-100 Probe

MP-100 PROBE

The MP-100 probe incorporates the latest magnetic technologies. Though similar to the MP-1 probe, the new MP-100 probe has a much higher gauss strength and three times the efficiency of the MP-1. The MP-100 does not require water cooling; however, it does allow for optional water cooling.

For added convenience and flexibility, it also features a detachable control cable. Single-axis probe adapts to conventional torches. A variety of return rings and tips are available for different configurations.

MP-1 Probe

MP-1 PROBE

The MP-1 is a single-tip, water-cooled probe that adapts to conventional torches. The MP-1 works well in tight clearances and is primarily used to weave the arc across the seam or to stabilize the arc.

MP-2 Probe

MP-2 PROBE

The dual-tip MP-2 slips over a conventional TIG torch and can be used either for cross-seam weaving or in-line weaving. In-line weave is primarily used in tube mills to preheat the tube, giving increased weld travel speeds.

MP-22 Probe

MP-22 PROBE

Use the MP-22 probe with the MA-20 control unit only. This twin-tip side-mount unit is capable of delivering the full 600 gauss magnetic field to the welding arc area. Though normally used in an air-cooled mode, if necessary, the MP-22 can also be water-cooled.

MP-4 Probe

MP-4 PROBE

With four independently controlled magnetic coils, the MP-4 probe has the highest capacity for multiple arc and weld bead profiles. It is used with the MA-40 control unit only.

The AP Automation MA-40 Control Unit and MP-4 Probe provide the ability to shift the entire arc pattern relative to the weld seam with position controls, as shown below.
