    Fume Guns FAQs

    Straight answers to the questions people ask most when choosing and using fume extraction MIG torches.

    What is a fume extraction MIG torch and how is it different from a normal one?icon-minus-redicon-plus-red

    It is a MIG torch with a built-in extraction path. A nozzle around the gas shroud draws fume in as it is produced, through a second hose that runs alongside the main cable to an extraction unit. This captures fume right at the source, before it reaches your breathing zone.

    The welding side works like a standard torch, but the torch is a little heavier and bulkier, and it needs a suitable extractor to work.

    Will it fit my machine?icon-minus-redicon-plus-red

    The torch end must match your machine's torch connection, commonly a Euro type fitting. The extraction hose then connects to the extractor, not to the welding machine.

    Check the connector type on your machine and the hose fitting on your extractor. If either does not match, ask before buying, as adaptors can reduce performance or fit badly.

    Do I need a special extractor to use one?icon-minus-redicon-plus-red

    Yes, you need an extractor that is specified for use with extraction torches. Many are designed to pull a strong suction through a narrow hose rather than moving a large volume of air through a wide arm, but the exact design differs between makers, so check what your torch and extractor require.

    The extractor must be able to draw enough air through the torch, and the hose connections must match. Weak suction means poor capture, while suction that is too strong can disturb the shielding gas. Check the manuals for both the torch and the extractor before you buy.

    How do I choose the right current rating and length?icon-minus-redicon-plus-red

    Pick a rating comfortably above the current you weld at, for the gas you use and the duty you need, as the real rating is affected by both. Then choose the shortest length that lets you reach the work, because longer cables are heavier, reduce suction at the nozzle and are harder to handle.

    Check the maker's ratings for your gas, not just the headline figure.
