High Tensile Steel Arc Welding Electrodes

C-28

CNS E5028
JIS D5028
AWS E7028

Description?G

The C-28 is an AWS E 7028 electrode. This is a high speed electrode when used for fillet welds. It is an exceptionally fast welding electrode when used down hand in properly designed weld joints or in horizontal fillet welds where equal leg fillets are desirable. The arc force minimizes slag entrapment while the slag is self removing in most applications.

Application?G

Railroad cars, structurals, earth moving equipment, plate fabrication and mining machinery.
