Product information

The OFG-285 consists of a main unit with a safety circuit and a swing arm conduit to an electrode head. The main box can be mounted to brackets 50 mm (2”) outside a launder. The electrode head is to be swung over the molten metal and leveled so that the ends of the electrodes hit just above the maximum allowed level in the launder. The electrode head can be swung out from the launder during maintenance.
