The cycle time to Demag, after the Coil is placed on the end of a Pipe, is less than 30 seconds. The Reversing and Reducing DC Demag lasts for over a week, requiring a Demag Crew work ahead of the Welders, not slowing production. To ensure demagnetization has been achieved, operators need to use a gauss meter to check the pipes' weld bevel. Generally an acceptable level of magnetization for welding (manual or automatic) is a field of ±2 Gauss.
Coil Models from the WDV-14-PD and below weigh less than 60 Pounds (27kg) are intended to be handled manually by the operator. The WDV-16-PD weighs just over 100 Pounds (45kg) and is intended to be positioned with a utility crane. The WDV-60-PD weighs just over 1000 Pounds (455kg), requiring the use of a dual wheel truck with a bumper mount crane. The same truck will require a generator appropriately sized for the Coil. A WDV-8-PD requires 1500 watts, while the WDV-60-PD requires 15 Kilowatts, making a 1 ton truck acceptable. Most modern engine driven Welders as used on a Pipeline Right of Way, have sufficient AC Power for even the largest WDV-PD Coils.
