SifGun 350 Torch Neck Insulator

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.

Sif Part Number: EXTEVO900400

Specifications

The SifGun Evolution welding torches are designed for a maximum open-circuit DC voltage of 113V (maximum voltage). Prior to welding, please make sure that your power supply complies with this specification. The SifGun evolution welding torches are designed for indoor use only. Do not use the welding torch at ambient temperatures exceeding 40°C (104°F).

The welding torches operate exclusively in the MIG and MAG processes. For safety reasons, WELDABILITY SIF does not authorize any modification or post-manufacturing alteration to the torch. The alteration will void manufacturing warranty automatically. Fume extraction welding torches are to be used with a mobile or centralized extraction unit.

SifGun Evolution fume extraction torches must be used with the leather protection mounted on the torch assembly (supplied).

The water cooled torches have to be connected to a cooling system. Attach the blue hose of the Euro-Connector to the output of the cooling system and the red hose to the cooling system return. Please refer also to the operation manual of the cooling system.

Prepare 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.
