Straight Electrodes tuffaloy-logo

standard_straight_tips_main2

Straight electrodes from TUFFALOY are distinguished for their high conductivity and resistance to deformation, which are the two major requirements of resistance welding electrodes.  Modern manufacturing methods and constant scientific quality control make the difference, starting with the alloying of pure copper, through bar extrusion, and the conversion of this high-quality bar stock into welding electrodes.

TUFFALOY ensures conformity to all standard dimensions. Before shipment, all electrodes must pass inspection by gage for uniform length, taper, and outline of point.

The bright shiny look of TUFFALOY electrodes is the result of a passivation process that eliminates excessive oxidation. It reflects the deep-down quality built into these electrodes and into all TUFFALOY products.

Only RWMA Class 1 (TUFFALOY 88) and Class 2 (TUFFALOY 77) electrodes are listed here. Class 3 alloy (TUFFALOY 55) electrodes are also available. For recommended uses of these alloys, see “Help Aids” in the upper right hand corner of this page.

To order Class 3 alloy electrodes, change description code to indicate it: see “Key to Description”, above.
