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.

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.

5.2 Insertion of the liner
From the EURO-connector, insert the liner into the torch assembly until it sticks out of the torch head. Close the wire feeder protection and turn on the power supply. Press the ‘inch’ button of the wire feeder until the wire electrode emerges from the contact tip of the torch head.
Attention! The wire electrode feed out can cause bodily injuries! When activating the trigger, electric tension may occur. If the torch head touches conducting materials, welding may be activated unintentionally
Wire feed rate may be adjusted by using the potentiometer of the power supply. When changing the wire electrode diameter, make sure to change the contact tip as well.

5.3 Connection of the torch assembly (water-cooled torches)
Make sure that the minimum quantity of cooling liquid for the cooler is adhered to.
Attach the blue hose of the Euro-Connector to the output of the cooling system and the red hose to the cooling system return.
Make sure to follow the instructions regarding cooling liquid as indicated by the manufacturer of the power source.
Bleed the cooling circuit before the first use of the torch assembly.

5.4 Controlling the shielding gas
Make sure that all shielding gas connections are airtight.
The nature and the quantity of shielding gas depends on the welding application and on the gas nozzle type. Set in accordance with your welding procedure (WPS).
Loosen the drive rollers and cut the wire electrode flush with the gas nozzle using a cutter.
Slightly open the gas cylinder valve and push the torch trigger or the gas test button on your wire feeder: shielding gas comes out. Place the flowmeter in a vertical position on the gas nozzle (Fig. 1) and adjust the gas volume on the regulator.

Attention: Poor gas protection leads to poor welding quality.

5.5 Connection of extraction unit
The SifGun Evolution extraction torches must be connected to an extraction unit to ensure extraction of welding fumes.
All indicated values apply only under the use with a fume extraction unit.
Connect the torch to an extraction unit by a flexible hose with a length which does not exceed 10m. On the torch side, the hose is connected to the T-piece besides the EURO-connector using the multi-diameter reducer part supplied, which you must cut to size. On the extraction unit side, the hose is connected to the sleeve of the filtration housing (there may be two entries for the connection of two welding torches on the same extraction unit on a twin entry extraction unit).
Please refer to the extraction unit operation manual for further information.

5.6 Deactivation
After welding, only deactivate the power source after shielding gas flow has stopped. Turn off the shielding gas supply. When using the extraction unit in automatic mode, make sure to only switch off the unit after the automatic end of extraction. In manual mode, we recommend keeping the extraction unit turned on for a couple of minutes after welding to cool down the extraction torch.

Maintenance

Risk of bodily injuries: Before performing any inspection or maintenance, always unplug the welding torch. Make sure that the power supply cannot be turned on by anyone else. Risks of bodily injuries from flying particles.
Always wear appropriate protective wear, safety goggles and respiratory protection!
Due to the use of high-quality components, our extraction torches need little maintenance. In order to optimize efficiency and to ensure continued functionality of the torch we recommend regular maintenance. Individual checks and maintenance tasks should be performed at regular intervals, depending on the conditions under which the welding torch is operated. We recommend the creation of individual maintenance schedules for each user individually. All regular and scheduled maintenance of the welding torch should be recorded.

To help ensure trouble-free functioning, the following inspections should be made at regular intervals:

• General visual inspection of the welding torch for any sign of damage or wear.
• Check all removable connectors to ensure that they are properly situated.

Replace the following items as needed:

• Insulating inserts
• Contact tips,
• Gas nozzle and all other consumables.
• To avoid leakage, check the connectors and connecting hoses. Avoid undue torsion and traction on the torch.
• Depending on the wire quality, remove any abraded wire and change the liner regularly.

6.1 Changing the liner
Loosen the knurled nut holding the liner on the EURO-connector using MIG helper pliers (ET001W).
Pull out the old liner and blow out the liner with compressed air (max. 6 bar). Press the liner all the way into the torch assembly until it rests against the contact tip and hold it there. Now gently tighten the knurled nut on the EURO-connector and cut the liner close to the EURO-connector.
According to the wire diameter, we recommend the use of the installation tool from WELDABILITY SIF.
Attention: If the clamping screw which secures the liner is fastened too tight, it will deform the liner and impede the feeding of the wire.

6.2 Water-cooled welding torch
Thermodynamic equilibrium is set up between the welding torch and the cooling system. The heat absorbed by the torch head (depending on welding current) is transported by the cooling liquid to the cooler. In case of cooler malfunction or blockage overheating may occur and deteriorate the welding torch. The maximum permissible welding currents given on the “technical data” page are applicable under the following conditions: Direct coupling via the supply line to the cooling system. Welding torch length of 4m. An efficient cooling system with clean cooling fins and filters.

Ambient temperature of 20°C (68°F).
Check the filling level of the cooling system and replenish the coolant as necessary. Check the cooling circuits for leaks regularly.
Always prevent coolant liquid from entering the wire guide. Water leaking can adversely affect the quality of welding.

Parameters for water-cooled manual or robotic welding torches according to EN 60974-7.
