When connecting the hose package:
• Be sure to observe the minimum amount of coolant in the cooling unit.
• Make sure that the coolant supply (blue) and return (red) hoses are correctly
connected. To guarantee the life of your torch, we advise you to refer to the
coolant manufacturer's recommendations.
• Be sure to purge the cooling system the first time you use the torch.
The 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 hose package.
From the EURO-connector, insert the liner into the hose package until it sticks out the torch
head. Close the wire feeder protection and turn on the power supply. Press the thread button
of the wire feeder until the wire electrode emerges from the contact tip of the torch head.
Make sure that all gas connections are tight. The choice of the type of shielding gas
depends on the intended welding job and the type of gas nozzle.
Pre-connection operation: Open the valve of the gas cylinder very briefly before making the
connection. This operation removes any impurities.
Gas check: Loosen the drive system, then cut (with pliers) the welding wire flush with the
gas nozzle. Gently open the cylinder valve. Hold the contact trigger of the torch down (gas
escapes).

The amount of shielding gas should ideally correspond to the diameter
of the gas nozzle: gas nozzle Ø16 -> 15-16 l/min. Adjust the amount
of shielding gas if necessary. Place the flowmeter in a vertical position
on the gas nozzle (Fig.1) and adjust the gas volume on the regulator.
Warning : Poor gas protection leads to poor

welding quality.
