1. The SifGun Fume Extraction Torch
The SifGun Fume Extraction Torch is a patented MIG welding torch with integrated extraction at
the nozzle of the welding torch. Therefore the extraction is close to the weld pool, so the fumes
coming from the welding process are extracted immediately. As a result the welder is exposed to
up to 95% less welding fumes.
Because of the conic shape of the nozzle, the protective gas exits at a high speed and is not
sucked away by the extraction. The quality of the welding process remains the same as with a
welding torch without integrated extraction.
The welding torch is delivered ‘ready to use’. It only has to be connected to a welding machine and
extraction unit. The SifGun Fume Extraction Torch is available in a air- and water-cooled version
The welding torches in this manual have been build in compliance with:
• EN 60974-7 Arc Welding Equipment Part 7: Torches
• 2006/95/EC Low Voltage Directive
• 2004/108/EC Electromagnetic Compatibility
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 his
authorised dealers.
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.

2. Safety
WARNING
READ THESE SAFETY INSTRUCTIONS CAREFULLY.
Failure to observe these safety instructions can lead to serious injury and/or damage to the
product. Only operators with relevant knowledge of arc welding should use this product.
• The vibration of the welding torch is less than 2.5m/s². No special precautions are required
related to vibrations.
• Arc welding can injure eyes, burn skin and cause hearing damage. Therefore:
- Use welding shield with lter complying with respectively the EN 175 and EN 379 standards.
- Wear proper protective clothing and ear protection.
- Make sure others are protected (e.g. curtains) from arc rays and ashing.
• Remove all combustible materials – including liquid and gaseous fuels, cloth, sawdust, wood,
paints and solvents - from the work area or completely cover the materials with a protective
non-ammable covering. Fire extinguishing equipment should be ready at hand for instant use.
Pay attention to spatter/dross created during welding; sparks can cause re several hours after
welding has nished!
• Work pieces must be completely cleaned so that no substances on the material, such as chlori-
nated solvents, can produce ammable or toxic vapours.
• Do not weld containers that have held combustibles.
• Always check cables before operating the machine. Defective cables may cause injury and/or
re.
• Do not make temporary repairs. Repairs should be made by qualied personnel.
• Do not pull cable assembly across sharp edges or expose to welding spatter or hot surface.
• To prevent electric shock, isolate yourself by using proper protective clothing and insulating
mats. DO NOT wear wet clothing!
• Do not exceed power rating. Overload can lead to torch damage, destruction and/or injuries.
• Turn o primary power before working on torch parts and/or replacing consumables.
• Do not breathe fumes or gases from welding. Welding fumes are harmful; lead, cadmium,
copper, zinc, mercury, stainless steel, galvanised steel and beryllium in particular. Therefore,
use ventilation or an extraction system to ensure that Maximum Admissible Concentration of
harmful substances (MAC) level is not exceeded.
• Use proper gas for the welding process (argon or helium) and pressure reducing regulator.
• Keep cylinders in an upright position. When not in use, keep cylinder valves closed. Keep cylin-
ders away from heat, sparks or ame.
• Follow the pressurised gas manufacturer’s operating instructions for mounting the regulator to
the gas cylinder.
