No. 726
This line of furnaces provides new, advanced techniques in fast, efficient melting of lead, babbitt, tin, zinc, as well as all other low and medium-fusion metals and alloys. Furnaces with blowers are used to melt aluminum if metal impurities caused by cast iron pot are not objectionable.
Each furnace features Johnson’s automatic spark ignition system and safety controls. Quality insulation assures furnace efficiency. Separate exhaust vents direct hot gases away from operator. Furnaces (without asterisks below) are equipped with powerful Johnson atmospheric burners for fast heat-up and recovery rate. Bodies are constructed of reinforced steel to give maximum life under conditions of continuous operation.
Heavy-wall cast iron pots are supplied with all models. Automatic temperature controls are also available at extra cost.
For high production jobs, Johnson Models 527, 719, 721, 725, and 726 have blast-type burners powered by a blower. These models have same quality construction features mentioned above. The Johnson Automatic Spark Ignition System and Safety Equipment are also included.
