Stainless Steel Welding Electrodes
E307-16 - Isoarc 307

Descriptions
ISOARC 307 Stainless steel

Characteristics
This electrode is specially formulated to weld at low amperage to ensure minimum distortion. The ISOARC 307 has good ignition and re-ignition properties, good slag removal and minimal loss through spatter. The high recovery rate of 180% ensures fast deposition with a minimum dilution of the base metal.

Applications
ISOARC 307 is used on crossing and points, gears, hot dies, rolls, valves, shafts, gear-teeth, machine parts and heavily loaded welds. Because of its high heat resistant properties, it is ideal as a buffer layer prior to hot working hard-facing applications.

Procedures
Keep the arc short to medium. DO not weave more than three times the diameter of the electrode. Pre-heat up to 250 degrees on steels with poor weldability. Pre-heating is not required for other steels. Always use dry electrodes.

Redrying
Should electrodes become moist re-dry at 350° C for 1 hour
