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 modications 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

welding machine’s instructions thoroughly before using our welding torches.

The manufacturer reserves the right, whenever necessary and without prior notice, to amend

these instructions as a result of clerical or printing errors, incorrect information, or the addition

of improvements.

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 qualied 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:

www.sifweld.com

3. Technical specications

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

specication. 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 modication 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 inammable 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 specications, the extraction welding torch can be congured with

dierent gas nozzles, contact tips and gas diusers. 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.

www.sifweld.com

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.

www.sifweld.com

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.
