4 TECHNICAL DATA
Duty cycle
The duty cycle refers to the time as a percentage of a ten-minute period that you can weld at
a certain load without overloading. The duty cycle is valid for 40 °C / 104 °F, or below.
General torch data with reference to IEC/EN 60 974−7
Type of guidance: Manual
Wire type: Standard round wire
Voltage rating: The control circuit and trigger switch are
rated for a voltage of 42 V, max. 1 A
Specifications of the torch cooling circuit (for
liquid cooled torches only):
• minimum flow 1.2 l/min
• min. water pressure: 2.5 bar
• max. water pressure: 3.5 bar
• input temperature: max. 40 °C
• return temperature: max. 60 °C
• cooling capacity: min. 1000 W, up to
2000 W depending on the application
Liquid cooled torches
Return temperatures of more than 60 °C can shorten the lifetime of the torch or cause
damage or destruction of the torch. The cooler must always be filled with sufficient cooling
liquid, refer to the instruction manual for the cooling unit. In case of a high thermal load on
the torch, use a cooler with sufficient capacity. Use only special cooling fluid containing
corrosion inhibitors for welding torches. For suitable products, contact your nearest ESAB
dealer.
The ratings are valid for cable lengths from 3.0 to 5.0 m.
The rated loads refer to a standardized case of use. Under special conditions, e.g. in case of
high heat reflection on the torch, the torch could overheat even when operated below the
rated load. In this case choose a more powerful model or lower the duty cycle.
Conditions of intended use
1. The welding torch should only be used within the above-mentioned
technical specifications and for its intended purpose.
2. The type of torch must be chosen according to the welding application. The required
duty-cycle and load, the type of cooling, guiding method and the wire diameter have to
be considered. If increased requirements exist, for example caused by pre-heated
work pieces, high heat reflection in corners, etc. these must be taken into account by
choosing a welding torch with adequate reserve in rated load.
3. The product must be protected from humidity and moisture during transport, storage
and operation.
