Edwards Engineering has been supplying innovative solutions to the sugar industry for more than 55 years. The Edwards Mavrex™ automatic arcing system is
purpose-built and is another in the extensive line of products designed to enhance sugar mill efficiency.

The Mavrex system provides increased arcing efficiency while promoting longer roll life and improved crushing efficiency.

Features

• Simplicity – Ease of operation, training and maintenance

• Repeatability – Highly accurate position control • Versatility – Can be used for straight line welding, roll building or arcing

• Reliability – Field-proven components designed for on-site maintenance use

• Compact – Quickly disassembled with largest component less than 600 mm x 600 mm

• Lightweight/Portable – Total system weighs only 70 Kg. Heaviest component 20 Kg

• Waterproof – Can be used in virtually any roll location under any condition

• Safety Shutdown – Will shut down with any unexpected mill stoppages

• Weld Current Shutdown – Systems stops with weld current failure

Benefits

• Lower Costs– Reduce consumable consumption by up to 75%

• Reduced Time – Roll arced with three faces in as little as two hours

• Flexible– One operator can operate two systems simultaneously

• Repeatable – No manual input needed for repeatable roll welding process

• Improved Safety – Operator is removed from hazardous fumes

• Planned – Welding tasks can be scheduled in workshop during slack
times

System Components

• Main Control Box – Rugged, waterproof housing with needed controls to operate the Mavrex system. Index controller allows programming flexibility for arcing up to 7 (or more) locations on each roll tooth.

• Remote Pendant – Allows remote or close-up adjustments of all welding functions during operations – centering, inching , direction, carriage and wire speed and weld voltage.

• Main Beam – High strength, yet inexpensive for permanent positioning to reduce set-up times

• Traversing Carriage – Fitted with variable speed DC motor with robot-style
encoder to provide infinitely adjustable pitch settings for precision and repeatability.

• Weld Arm – Fully automatic controlled electronically from the pendant and
specifically designed for better welding torch rigidity.

• Welding Torch – Heavy duty, open arc type rated for continuous 600 amps and requires no shielding gas or water cooling. Can be adjusted in forward plane from –10 to +45 horizontal

• Wire Feeder – PA-11 extra heavy-duty constant potential type with four drive rolls for continuous, positive arcing wire feed. Variety of rolls can be used, either mounted on wire feeder or at a remote dispenser.
