caps and shanks
TUFFALOY
Tuffcap electrodes consist of two pieces: a shank and
a replaceable cap. These two-part electrodes can offer
major economies, because when the nose geometry is
worn out, only the cap needs to be replaced. And it costs
far less than a standard one-piece electrode. (A Tuffcap
shank will normally outlast twenty caps.) Also, electrode
inventory can be kept small because all nose designs
will fit the same size shank.
Female Cap Type
Electrode Assembly
TWO TYPES: TUFFALOY offers two kinds of Tuffcap
electrodes. One uses a male cap that fits into the shank.
The other has a female cap that fits over the shank.
FEMALE AND MALE CAPS are available in the widest
range of sizes, alloys, and styles. They are made in both
Class 1 and Class 2 alloy, and in sizes to fit- shanks sized
4 through 7 RW. Male caps are more effectively cooled
than female caps.
Male Cap Type
Electrode Assembly
ALL CAPS are made with the same nose designs in
conformance with RWMA standards.
SHANKS are made of Class 2 alloy, either straight,
or bent to provide an offset. Shanks other than those
cataloged can be special ordered. Tuffcap, caps and
shanks should be used only in a directly opposed,
straight-line manner. They do not work as well as
standard electrodes on heavily coated metal such
as galvanized or tin-plate.
Size 5 RW straight
and offset style shanks
holding male type caps
with swivel heads.
These caps are cataloged
on pages 6 & 7.
TUFFTRODE-Z CAPS FOR COATED STEELS
To avoid electrode sticking problems common when
welding galvanized and aluminized materials, these
copper chrome-zirconium alloy caps are offered. They
give the same performance as dispersion-strengthened
caps but cost far less. They are Class 2 caps in
mechanical and physical properties.
Both male and female caps are offered in all the standard
nose designs.
NEW! SUPER NOSE DESIGN CAPS
To avoid mushrooming and brassing problems associated with standard designs, these caps
have a self-dressing weld face ring that acts as a control zone. The Super Nose caps are
available in TUFFALOY’s new “Z” material, that eliminates electrode sticking problems
common when welding galvanized and aluminized materials.
Both male and female designs are offered, designed to fit shanks with 5 RW taper.
