TUFFALOY

swivel tips

TUFFALOY

refractory metal-faced tips

Swivel tips have ball-jointed

swivel heads to compensate

for minor misalignment, and

to eliminate marking of the

work surface. They are all

machined from Class 2 alloy

bar stock. The S-and SS-

Series tip water hole does

not reach the head. In the

OS and OSH models, the

water does contact the

head, and O-rings are used

to seal it. In the SS Series

a spring is used to keep

pressure on head for

better positioning.

Class 1 and class 3

heads are also available.

*Will fit Tuffcap adapter shanks having No. 5 RW tapers, as shown on page 6.

Note: Standard swivel

tilt is approximately

18’, a 25’ swivel is

available on request.

Add suffix “HS” to

above part number.

The TUFFALOY copper-tungsten, tungsten and molybdenum-faced tips

listed here withstand greater heat and pressure, at the expense of

some conductivity. Besides being used for spot welding high resistance

base metals, they are useful in achieving “heat balance” when welding

dissimilar metals. (The higher resistance electrode is used against the

lower resistance, or thinner, member, to help contain the heat generated.)

They have the same diameters and tapers as the standard straight tips in

this catalog. Bodies are of Class 2 alloy. Lengths other than those shown

can be ordered.

Taper
