Equatip Holders

  • For No. 4 RW Electrodes 1-in. Shank
The Equatip dual tip holder is a smaller version of the Equa-Press holder (on next page). It is more compact, and is more economical for those applications where it will work equally well. An even smaller device, the Equatip adapter (not water-cooled) is shown in box below.

Using the Equatip holder, both tips contact the work squarely, because tip axes remain parallel to direction of force (unlike the Teeter-Tip adapters). An internal roller equalizes current and pressure between the two electrodes, and will compensate for work height variations up to 116".

The holders are ordered with either 1" or 1-12" spacing between barrels, and with tip sockets to accept either male Tuffcap caps (58" dia.) or straight No. 4 RW electrodes. (Bent tips are not recommended.) The distance between welds can be varied by rotating offset-nose tips in the barrels.

Equatip holders can be supplied with straight shanks for arm mounting, a tapered adapter shank for holder mounting, or a cylinder adapter shank to be clamped to a cylinder rod. Clamps are sold separately.

Equatip holders can be used with forces up to 1000 lbs.

The Light Duty Equatip adapter works like the Heavy Duty Equatip holder, but it is not water-cooled and is meant for less demanding jobs. It costs less, and it's a little smaller, barrels being 58" apart. It uses RWMA male cap taper #4 electrodes.

Cylinder-Mounted Multi-Spot Holders

  • 7/8-14 Threads for 4 and 5 RW Adapters Part No. 194-1578
  • 1/2-14 NPT Threads for 4 and 5 RW Adapters Part No. 194-1588
These standard-tip holders are mounted directly to air or hydraulic cylinder pistons. They are ideal for assembling special multi-head resistance welding equipment. Current and coolant water are brought to each of the holders separately.

Electrode adapters for the tip diameter being used and in lengths to suit your set-up are ordered separetely. Water tubes, for carrying water into the tip, should also be ordered separately.

TUFFALOY offers both straight and offset holders for cylinder mounting. Clamps (see below), hose connections, water tubes and adapters not included. Order separately.

Off-Set Holders

Offset holders are offered in eight offset sizes, from 18 to 1 inch. The standard models have a 12-NPT adapter socket, to hold adapters for 4 & 5RW electrodes. Ordering a 34-NPT socket will permit adapters for 6 & 7RW electrodes to be used.

Replaceable Cap

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.

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.

ALL CAPS are made with the same nose designs in conformance with RWMA standards.

MALE AND FEMALE 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.

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.
