2. System Description

(1) Features

Overview

This manual is organized to assist you in getting productive quickly with your

TL-080B/BF.

TL-080B/BF come in different sizes and configurations and may be installed on

our mounting hardware, custom mounting posts, or installed directly on your

equipment using the two tapped holes on the rear of the weld head. Some heads

are manually-actuated, others are air-actuated.

Mounting templates and all necessary installation hardware are shipped with each

weld head.

TL-080B/BF are precision, low inertia, force-fired Weld Heads with a narrow

vertical profile. The 1-3/4 inch (4.5 cm) width, 1 in. (2.5 cm) stroke, 20 pound (89

N) maximum force, and throat depth allow their use in a wide variety of precision

resistance welding applications. Offset electrode holder is available. The

dimensions of the mounting post and the main shaft have been selected to ensure

that the electrodes do not "wipe" more than 0.003 in. (0.076 mm) on the 20 lb. (89

N) heads. This is an important consideration in critical welding applications such

as hermetic seals and pressure transducers.

TL-080B/BF is a "production line" head with a bearing life designed for a minimum

of 20 million operations. Our Weld Heads excel at precisely placing consistent,

high quality welds. Their low inertia, lightweight design assures fast dynamic

response, allowing the electrodes to follow the minute expansion and contraction

of the weld joint as it heats and cools during the welding cycle. A differential

motion Force-Firing System initiates the power source at the precise moment the

Preset Firing Force is applied to the workpieces. Linear ball bearing bushings and

an oversized, anti-rotational bearing system provide true, vertical in-line electrode

motion, assuring smooth vertical travel of the upper electrode arm. This system

minimizes the wiping action of the electrodes, even at maximum force settings.

Preset Firing Force

Firing force is continuously adjustable from 0.5 lbs (2.2 N) to 20 lbs. (89 N). An

adjustable Tare Spring compensates for the weight of the electrode holders. The

Firing Force Adjustment Cam easily adjusts the sensitivity of the Firing Force

Switch.

Up And Down Stops

TL-080B/BF have adjustable Upstops and Downstops. The Downstop can be used

to limit excessive downward travel. The Upstop controls the stroke, and

consequently, the travel time of the head. In automated machine applications,

using a stroke of less than 1/8 in. (3.2 mm) may significantly reduce bearing life.

Electrodes

TL-080B/BF accept a wide variety of standard and special purpose electrodes.

There are models available, which accept 1/8 in. (3.2 mm), Unibond®, and Unitip®

Electrodes. The optional Model ETB4 Table Electrode fits TL-80.

Insulation

The Terminal Block, Flexible Copper Strap, and Upper Electrode Assembly are

electrically insulated from the frame of the Weld Head. The Frame, Support Post,

and Support Base are grounded to the bench top.

Welding Cables

#2 Welding Cables is provided to connect TL-080B/BF Heads to the power source.

Our Heads deliver maximum performance when used with the appropriate our

power sources.

Footpedal Actuation

TL-080B/BF Weld Heads, model number suffix "F," are footpedal (manually)

actuated. The Model CP Cable Pedal is a treadle-type cable actuator providing an

approximate 3 to 1 mechanical advantage. This pedal is used with TL-80BF.

Air Actuation

TL-80B is equipped with a top mounted Air Cylinder with two Flow Controls, one

or two Air Pressure Regulators, and a four-way Solenoid, making it easy to

incorporate these weld heads into automated welding systems. The Air Solenoid

Valve is available with 115 V AC ratings. Two Flow Controls are used to adjust the

up and down speed of the upper electrode. The Air Solenoid Valve can be

energized by most of our power sources, or by a Model FSAC Footswitch. The

Footswitch can be a single or two level type, dependent upon the power supply

and the user's preference. We suggest that lubricators not be used in "clean"

environments. However, the user will then be required to periodically put a few

drops of oil in the cylinder. Some users use lubricators, some do not.

(3) Welding Capabilities

Series Welding

In series welding applications, both electrodes contact

the same surface of each workpiece. The weld current

flows from one electrode through the workpiece to the

other electrode. This technique is used to weld

workpieces which have only one surface accessible.

The work surface, or a user supplied fixture, acts as a

support for the workpieces in series welding. If the Table

is insulated from the workpieces, there is no possibility

of shunting current away from the (-) electrode.

Step Welding

In step welding, the size of the weld and the surface

marking is frequently controlled by the diameter of the

face of each electrode. If the (+) Electrode is significantly

larger than the (-) Electrode the lower workpiece will not

have any marking and the weld will be under the (-)

Electrode.

The Table Electrode, or a user supplied fixture, acts as a

support for the workpieces in step welding.

If the Table is insulated from the workpieces, there is no

possibility of shunting current away from the (-)

electrode.
