The Diverse Zeromag ZM100A is a demagnetizing system for steel tubes and plates. It is used to reduce the magnetic field levels in welding joint preparations to levels which are low enough to enable welding to proceed. Zeromag is used to eliminate arc blow which can occur when the parts to be welded are magnetic – this shows up as high magnetic field levels in the joint preparation.


– Overcoming Arc blow

– Pipe butt welding

– Plate and pressure vessel welding

– Use with TIG, MIG, MMA and Sub-arc processes.
