Important note!
▪ The torch capacity values given refer to a standard application case using standard
accessories.
▪ The torch and cable assembly capacity drop when using pulsed arc power sources.
▪ In special cases e.g. in the event of very high reflective heat, the torch may overheat even
under less load than the maximum rated capacity. In this case, the welding duration in the
duty cycle must be reduced, a more powerful torch selected, or the welding conditions
must be improved.
▪ ESAB products are manufactured to the current state of the art and are safe to operate if
they are used as intended.
▪ The ratings are valid for cable lengths 8 and 12 m.
▪ For special cable lengths > 12m, a reduction in performance is required due to the
increased heat influence.
▪ For water-cooled special cable lengths > 12m a sufficient dimensioned cooling device is
needed (cooling capacity > 2KW). The coolant flow rate should not fall below 1.2 L / min.
2.3 Selection of a suitable torch
The torch model must 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 considered by choosing a
welding torch with adequate reserve in power rating (see section 2.2).
