See our comparison test with SifGun on-torch extraction, showing the difference with and without this system in place.
Extraction takes place close to the MIG weld zone, but without disrupting your shielding gas, so the fumes coming from the welding process are removed immediately. As a result the user's exposure to welding fumes is reduced by up to 95%.
We can see the alarming difference between using a fume extraction MIG torch with vacuum system and what happens when this extraction isn’t used. Keep your eyes peeled at 00:12 when the extraction is switched off. The welder becomes engulfed in the fumes, potentially risking his respiratory health.
On-torch extraction uses high-vacuum technology, i.e. high speed extraction and low air volumes to extract the fumes. Older extraction torch models can disrupt shielding gas coverage (depending on gas type used), but the SifGun Fume Extractor MIG torches are engineered differently.
MIG fume-torches, such as the SifGun Fume Extractor are now available - in air- and water-cooled models - with advanced design features that enable 95% fume-removal at-source, without the need to adjust the flow–rate of shielding gases and with the weight and manoeuvrability of a regular MIG torch.
