Postalloy® 2821-MCO Sugar Mill Roll Arcing Roughening Wire
Postalloy® 2821-MCO is a chromium carbide hardface alloy that produces a "Spatter Weld" (Chapisco), from small to large to enhance the gripping action. This versatility can meet the needs of all desired sugar mill roll rough surface requirements for pulling the cane during processing. It is easily applied during production or in shop roll maintenance. An ideal alloy for applications involving high abrasion and moderate impact.

Welding Parameters
Current Type: DC Electrode Positive
| Volts | Amps | Diameter | Stick Out |
|---|---|---|---|
| 22-28 | 175-300 | 1/16" (1.6mm) | 1"-1¼"(25-32mm) |
| 23-26 | 250-350 | 3/32" (2.4mm) | 1"-1½"(25-38mm) |
Welding Procedure:
When welding out of position, use the lower range of amperages and voltages. In addition, a gas cover may be useful, especially when using a constant current power source and voltage sensing feeder.
