2.2 Specifications
ESAB MXH PP
Field of application
ESAB MIG/MAG welding torches are intended for use on CE-compliant welding
power sources for metal inert gas welding (MIG), metal active gas welding (MAG)
and metal inert gas soldering processes with commercially-available round wires.
The torches may not be used for other processes.
Type of guidance
by hand
Voltage rating
The torch is rated for a welding voltage of max. 113 V (peak value).
The control circuit (switch or micro switch) is rated for a voltage
of 50 V, max. 1 A.
Remote control devices with electronic elements may be subject to individual
specifications.
Cooling method
Gas-cooled and water-cooled versions are available. The water-cooled version
includes the additional connections for water inlet and return.
Capacity
The maximum welding current depends on the torch version used, please refer to
the type plate on the machine side connector of the torch for applicable data.
The following maximum values apply:
▪ MXH 315 PP (gas-cooled): Mix: 270A; CO

Important note!
Return temperatures of more than 60 °C / 140° F may cause
damage or destroy the cable assembly. The cooler must always be
filled with enough cooling liquid, please consult the user manual of
the cooling unit. In case of a high thermal load on the torch, please
use a cooler with enough capacity.
