WARNING!

Arc welding and cutting may cause injury to yourself and others. Take precautions

when welding and cutting.

ELECTRIC SHOCK - Can kill

• Install and ground the unit in accordance with instruction manual.

• Do not touch live electrical parts or electrodes with bare skin, wet gloves,

or wet clothing.

• Insulate yourself from work and ground.

• Ensure your working position is safe

ELECTRIC AND MAGNETIC FIELDS - Pose health risks

• Welders with pacemakers fitted should consult their doctor before welding.

EMF may interfere with some pacemakers.

• Exposure to EMF may have other health effects which are unknown.

• Welders should use the following procedures to minimize exposure to

EMF:

○ Route the electrode and work cables together on the same side of

your body. Secure them with tape when possible. Do not place your

body between the torch and work cables. Never coil the torch or work

cable around your body. Keep the welding power source and cables

as far away from your body as possible.

○ Connect the work cable to the workpiece as close as possible to the

area being welded.

FUMES AND GASES - Can be dangerous to your health

• Keep your head out of the fumes.

• Use ventilation, extraction at the arc, or both, to take fumes and gases

away from your breathing zone and the general area.

ARC RAYS - Can injure eyes and burn skin

• Protect your eyes and body. Use the correct welding screen and filter lens

and wear protective clothing.

• Protect bystanders with suitable screens or curtains.

NOISE - Excessive noise can damage hearing

Protect your ears. Use ear defenders or other hearing protection.

3 INTRODUCTION

The RT welding torch systems are developed for fully automatic MIG/MAG welding using

robots. The systems consist of a variety of Aristo RT torch necks designed for robotic use,

torch mounts, cable assemblies optimized for robotic use, and safety-off features to prevent

the system from damage in case of collision.

The standard RT welding system provides collision protection through the use of RTKS-2

which is a mechanical spring-loaded safety-off functionality. This can optionally be replaced

by RTFL-2 to take advantage of the collision detection function of the robot control system.

The standard RT welding system can be used with a variety of cable assembly types.

RTKSC-2 and RTFLC-2 torch mounts with Infiniturn or Helix cable assemblies are intended

for use in hollow wrist robot welding systems designed for advanced welding applications.

The safety-off mechanism in the RTKSC-2 torch mount allows for large elastic deflection of

the torch in case of collision. The Infiniturn and Helix cable assemblies are simple to install,

providing a highly reliable system with precise maneuvering capabilities.

In combination with the well-established Aristo RT robot welding torches, these constituents

create a highly reliable and long-lasting system which needs only a minimum of

maintenance.

The instruction manual is included on delivery of torch mounts and cable assemblies.

The ESAB ordering numbers, available accessories, spare parts, and wear parts are

found in the spare parts list.

4 TECHNICAL DATA

4.1 Welding torch neck

Choose your torch model according to the welding application. The required duty cycle and

capacity, the cooling method, and the wire diameter must be considered. If there are

increased requirements, for example caused by preheated work pieces or high heat

reflection in corners, take these into account by selecting a welding torch with adequate

reserve in its power rating.

RT welding torches are intended for the use with CE-conformant welding power sources for

the processes of Metal Inert Gas welding (MIG), Metal Active Gas welding (MAG) and MIG

Brazing with commercial round wires. Do not use the torch for other processes.

For pulsed arc welding of steel or aluminum welding, the RT82W water cooled torch must be

used.

4.3.1.1 RTKS-2 safety-off mechanism

The RTKS-2 safety mechanism is a spring supported device that protects the robot and the

torch system in case of a collision.

NOTE!

Do not disassemble the RTKS-2.

4.3.1.2 RTFL-2 intermediate flange

The rigid intermediate flange RTFL-2 can be used instead of the RTKS-2 if the robot has

an electronic collision detection system.

4.3.2 Torch mounts for hollow wrist system

In the hollow wrist system the Aristo RT welding torch necks are connected to the torch

mount KSC-2 or FLC-2.

The torch mount RTKSC-2 allows for elastic deflection of the torch in case of a collision. At

the same time, an electrical contact is opened, signaling the robot control to stop. After

resetting the error, the initial geometry and Tool Center Point (TCP) of the torch will be

reached with high precision. The system functions purely mechanically and is spring loaded.

The torch mount RTFLC-2 has no built-in safety-off function.

4.5.2 Cable assemblies for hollow wrist systems

The Infiniturn cable assembly allows endless rotation of the torch in both directions. At the

same time, cooling fluid, shielding gas, blow-out air, welding power, and the signal of the

safety-off mechanism are transferred.

The Helix cable assembly is designed for a rotational range of ±270° from the neutral

position. It can be used for welding tasks that do not require endless rotation.

The Infiniturn cable assemblies are available in gas and water cooled versions. The Helix

cable assemblies can be universally used for gas or water cooled applications.

NOTE!

Do not connect a Helix cable assembly operated with a gas cooled torch neck to a

water cooling system.
