4 TECHNICAL DATA

4.1 Welding torch

The torch model has to be chosen 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, high heat

reflection in corners, etc, these must be taken into account by selecting a welding torch with

adequate reserve in power rating.

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

the processes of metal inert gas welding (MIG), metal active gas welding (MAG) and metal

inert gas soldering with commercial round wires. Do not use the torch for other processes.

For aluminium welding the RT82W water cooled torch must be used.

See the spare parts list for available torch models.

nominal current)

For detailed information regarding the rating and technical specifications of your torch please

see the spare parts list included with the torch. The values for torch rating and duty cycle are

valid for a 10 min. cycle.

The indicated ratings refer to a standardized case of use. In special cases, e.g. in case of an

especially high heat reflection on the torch, the torch may overheat at lower currents than

indicated. In this case, please use a more powerful model or reduce the duty cycle.

The rating will be notably reduced with the use of pulsed arc power sources.

For cable assembly ratings, see section "Cable assemblies".

4.1.2 Cooling circuit limits

Valid for water cooled version only.
