1. Special Notes
(1) Safety Precautions
Prior to use, read these “Safety
Precautions” carefully to gain a full
understanding of the proper method of
use.
•The precautions listed here are designed
to ensure safe use and proactively
prevent risks and damage to the user and
other people.
All precautions are critical for safety.
Please read them all.
•The hazard signs have the following
meanings:
DANGER
Indicates a high risk of death or serious
injury if precautions are not correctly
observed.
WARNING
Indicates a risk of death or serious injury if
precautions are not correctly observed.
CAUTION
Indicates a risk of physical injury or damage to
product if precautions are not correctly
observed.
These symbols indicate
"prohibition." They are
warnings concerning
actions out of the
scope of the warranty
of the product.
These symbols indicate
actions that operators
must take.
Each symbol with a
triangle indicates a
DANGER, WARNING,
or CAUTION to the
operator.
DANGER

Burns or electric shock may result. Do not touch the inside of the Controller
other than for maintenance as described in the operation manual.
In the event of a problem, contact our serviceperson for internal inspection
and repair.
Never disassemble, repair or modify the Controller.
These actions can cause electric shock and fire. Do not do anything other
than the maintenance described in the operation manual.

WARNING
Do not insert your fingers or hands between the electrodes.
When welding, keep your fingers and hands away from the electrodes.
Do not touch any welded part or electrode during welding or just after
completion of welding.
The welded parts of a workpiece, electrodes, and the arm are very hot.
Do not touch them; burns may result.
Ground the Controller.
If the Controller is not grounded, electric shock may result.
Do not expose to water or other liquid.
Exposing electrical components to water or other liquid may result in electric
shock or short-circuiting.
Apply the specified supply voltage.
Application of a voltage outside the specified range may result in fire or
electric shock.
Use only the specified cables.
Use of a cable of insufficient capacity may result in fire.
Do not damage the power cable or connecting cables.
Do not walk on, twist, or pull on any cable.
The power cable and connecting cables may be broken, and that can cause
electric shock, short circuits and fire.
If any part needs to be repaired or replaced, consult us or your distributor.
Stop the operation if any trouble occurs.
Continuous operation after occurrence of a trouble such as burning smell,
abnormal sound, abnormal heat, smoke, etc. can cause electric shock and
fire. If such a trouble occurs, immediately consult us or your distributor.
Persons with pacemakers must stay clear of the welding machine.
A person who uses a pacemaker must not approach the welding machine or
walk around the welding shop while the welding machine is in operation,
without being permitted by his/her doctor. The welding machine generates a
magnetic field and has effects on the operation of the pacemaker while it is
turned on.
Protective gear must be worn.
Put on protective gear such as protective gloves, long-sleeve jacket, leather
apron, etc. Spatter can burn the skin if they touch the skin.
Wear protective glasses.
If you look at the flash directly during welding, your eyes may be damaged.
If any spatter gets in your eye, you may lose your eyesight.

CAUTION
Always use a terminal cover.
Touching the terminal block directly may result in electric shock. Be sure to
fit the block with a cover.
Connect the cables securely.
Improper connection of a cable may result in fire or electric shock.
Use proper tools (wire strippers, pressure wire connectors, etc.) for
terminal treatment of the connecting cables.
Do not cut the wire conductor; fire or electric shock may result.
Install the Controller on a firm and level surface.
If the Controller falls or drops, injury may result.
Do not place any container of water or other liquid on the Controller.
If water or other liquid spills, insulation will deteriorate, which may result in
electrical leakage and/or fire.
Keep combustible matter away from the Controller.
Spatter may ignite combustible matter. If it is impossible to remove all
combustible matter, cover it with non-combustible material.
Do not cover the Controller with a blanket, cloth, etc.
Do not cover the Controller with a blanket, cloth, etc. while it is in use.
The cover may be overheated and burned.
Do not use this Controller for any purpose other than welding.
Use of this Controller in a manner other than specified can cause electric
shock and fire.
Use ear protectors.
Loud noises can damage hearing.
Keep a fire extinguisher nearby.
Keep a fire extinguisher in the welding shop in case of fire.
Maintain and inspect the Controller periodically.
Maintain and inspect the Controller periodically, and repair any damage
nearby before starting operation.

(2) Precautions for Handling
Install the Controller securely on a firm and level surface, to ensure that it will not fall.
Do not install the Controller in the following locations:
Damp areas (where the humidity is above 90%), areas where chemicals are handled, dusty areas,
areas near a high noise source, areas where water may condense, areas exposed to large amounts
of vibration or shock, and areas where temperatures are above 45°C or below 0°C
Clean the exterior of the Controller using a soft, dry cloth or one slightly dampened with water. If the
Controller is very dirty, use diluted neutral detergent or alcohol. Do not use paint thinner, benzine, etc., as
they may discolor or deform the Controller.
Do not insert a screw, coin, etc. into the Controller, as they may cause a malfunction.
Operate the Controller in accordance with the method described in this operation manual.
Press switches/buttons carefully by hand. Handling them roughly (using a screwdriver or the tip of pen)
may result in a malfunction or failure.
Press switches/buttons one at a time. Pressing more than one switch/button at a time may result in a
malfunction or failure.
(3) On Disposal
This product incorporates parts containing gallium arsenide (GaAs). At the time of disposal,
separate it from general industrial waste or domestic waste and carry out the disposal in
accordance with applicable laws and regulations.

2. Features
The WELTOUCH CT-110E is a constant/alternating-current resistance weld control with a
15-schedule setting function. It is controlled by a microcomputer, allowing it to be applied to all
types of welding. Due to the plating-layer treatment by the pre-stage current, heat treatment by
the post-stage current, etc., splashing is prevented, the welding tip is protected from
overheating, and an ideal welding current can be set. In addition, the CT-110E can be applied
to all types of spot-welding machines by selecting the secondary-or primary-current feedback
constant-current control and source-voltage fluctuation compensation method. The required
items can be set very simply and easily. The CT-110E has a wide range of features, as
explained below.
1) Indicates the welding current, schedule set No., set time, etc. with an LED.
2) Stores up to 15 schedules according to the materials and thicknesses of the
workpieces to be welded.
3) Equipped with the 3-stage power-on system, and upslope and downslope
functions.
4) Supplies a stable welding current by the primary and secondary constant-current
control method and source-voltage fluctuation compensation method.
5) Has the welding mode applied to the high-tensile steel plate with a high initial
resistance
6) Includes functions for monitoring the current and conduction angle.
7) Comes with a cover to protect the touch panel from oil mist.
8) Has three counters to indicate the quantity of products, and other information.
