Overcomes arc blow

Portable Weld Demagnetizer

Reduces or eliminates the effects of magnetic arc blow

ZeroMag measures and neutralizes magnetic fields which may be present in the weld preparation region of mating steel components. The demagnetization process can be performed manually or automatically using ZM100A. ZeroMag is suitable for manual or automated welding processes.

DIVERSE demagnetizers are compact, ruggedly constructed units for use in typical welding site environments.
Hyperbaric versions are available on special quotaion. Simple and rapid to deploy, ZeroMag will greatly assist productivity, reducing welding times while minimising weld repairs and downtime associated with magnetic arc blow.

Recent developments to the Zeromag family include a robust set of stainless steel field probes and a computer controled add-in to degauss steel samples. The degauss option provides various demagnetizing strategies, and programmable speed of current change, BH loop fractional reduction and final step size.

With some large samples the number cycles around the BH loop will be large and the rate of change of current restricted. The Zeromag degauss option advises the degauss time in advance so that the best compriomise between production rates and good demagnetization can be realised.
