1. The SifGun Evolution Fume Extraction Torch
Thank you for purchasing a quality product from WELDABILITY SIF. For your own safety, please
read these operating instructions carefully before operating this product. The owner of the
product must make this operating manual available to each operator and ensure the operator
has read and fully understands the instructions prior to use. Keep the operating manual in a safe
place for future reference.
This operating manual contain both water and gas cooled extraction welding torches. Please
refer to the current spare parts list for further details on the particulars of your welding torch,
such as torch assembly, connectors and torch heads. This product conforms to the requirements
of IEC 60974-7.
Refer also to the operating instructions for the fume extraction unit, the power source and any
other device connected to the torch.
The welding torch is only to be used by experienced personnel. It is not allowed for untrained
persons to install, handle or maintain our welding torches. Welding torches must be checked
regularly in order to guaranty optimum life time expectancy.
The user is fully responsible for possible defects arising out of misuse, inadequate maintenance,
damage, poor repair, or modications by other parties than the original manufacturer, or their
authorised service centres.
The welding torch is a component of a complete welding system. The torch will generate an
electric arc when connected with the appropriate welding machine. Ensure that you read the

Danger of personal injury: The operator must wear appropriate protective gear.
Protect the working zone from air ow. Do not weld on painted surfaces. Do not
weld on wet surfaces. Never place your face, hand or other body parts in front of
the contact tip while feeding the wire electrode.
Danger for the hands: Your skin must not get in contact with the welding torch!
Always put on welding gloves before welding.
Danger of material damage or personal injury: Make sure that the torch cable
assembly is not twisted and does not chafe against sharp edges. Damaged
insulation of the cable assembly must be repaired by a qualied technician
immediately.
All control wires must be protected against over-tension to avoid damages to all
peripheral devices, such as robots, handling equipment, electronic contour units,
power sources or wire feeders.
Do not roll over this product with forklifts or similar.
Do not x the torch in a vice.
In case of an accident, disconnect the supplies of electric power, compressed air
and shielding gas immediately. In addition to this manual, always observe all
safety instructions and the relevant accident prevention regulations. Ensure you
follow and appropriate method statements, developed from a thorough
risk assessment.

All WELDABILITY SIF products are manufactured using the relevant technology and in accordance
with approved safety regulations. To avoid injuries when using your SifGun Evolution torch the
following safety requirements must be carefully observed:

3. Technical specications
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
specication. 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 modication 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.
3.1 Risks when operating the torch
Danger for your eyes
Injuries can be caused by metal lings, electrode fragments or weld spatter while
blowing the liner. Always wear eye protection for those operations.
Fire and explosion hazard by sparks
Do not weld near to inammable materials or liquids. Store those materials outside
the welding zone. Avoid re risks caused by sparks or hot pieces and keep re sources
monitored. Ensure the availability of re extinguishers and their correct functioning.
Danger for your ears because of the noise (sound pressure level)
Always wear ear protection.
3.2 Authorised operators
The SifGun Evolution welding torches must only be operated by trained competent persons who
are aware of the relevant safety instructions. The owner of the product must make this operating
manual available to each operator and ensure the operator has read and fully understands the
instructions prior to use. Any use by untrained persons is not permitted.

4. Instructions for use
According to the customer’s specications, the extraction welding torch can be congured with
dierent gas nozzles, contact tips and gas diusers. 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.

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 rst 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 ush 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 owmeter 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.
