4. Instructions for use
According to the customer’s specifications, the extraction welding torch can be configured with
different gas nozzles, contact tips and gas diffusers. Any welding operation at high power should
be performed with a gas nozzle of a large inner diameter.
At low power, gas nozzles of smaller inner diameter should be used. For aluminum welding, you
must use drive rollers with specially formed grooves in the wire feed system. Use a special capillary
liner with wire electrodes made of aluminium and stainless steel.
5. Installation
5.1 Preparation for welding
Prior to welding, please make sure that the torch head is correctly equipped with a contact tip and
a gas nozzle. Make sure that the welding current does not exceed permitted values. Please refer
to the related operating manuals for further information about the power source, the wire feeder,
the gas cylinder and cables. Refer to the existing technical literature for further information about
welding processes and application techniques.
The fume extraction welding torch features a compact connector (standard EURO-connector) with
a clamping nut. Always make sure that the clamping nut is well tightened. A loose contact may
cause heating of the torch assembly.
When using water cooled welding torches, connect the blue and red hose (blue: water output, red:
water return) to the corresponding connectors on the power supply or wire feeder.
