The suction torch is very common<\/strong> as a system of extraction of welding fumes in Northern European countries and generally in the “advanced” markets where there is a high sensitivity to the health protection of the welder<\/strong> and at the same time to energy savings. It is about a technical solution that has many advantages<\/strong> than the classic smoke suction systems, even if being technologically advanced requires a good technical culture and the willingness to change some process habits that the welder is not always willing to do.<\/p>\n

Let’s see how it works<\/h2>\n\n\n\n
Typical action of the suction torch: the welding fumes are sucked into the source<\/strong> where they are produced, thanks to a “mini” suction hood positioned on the torch.<\/p>\n

This obviously makes the system unique because if the welding fumes are picked up before, obviously they can not disperse after<\/strong>, so we will no longer have the classic smoke in mid-air around the workshop.<\/p>\n

The high-pressure suction effect that passes through the suction torch along its entire length therefore simultaneously performs two decisive functions<\/strong>:<\/p>\n

    \n
  • The extraction of fumes and micro welding dust and at the same time creates a barrier to protect the welding bath from drafts in the environment, very useful in shipyards, in large outdoor workshops, or welding near open doors.<\/li>\n
  • The dynamic cooling of the torch, which, due to the high speed of the air drawn in (50 m\/s) through which it is passed along its entire length, creates a high direct or indirect heat dissipation that the torch accumulates. The traditional liquid cooling becomes superfluous, at least up to 350 amps, that would make the torch even heavier and stiffer.<\/li>\n<\/ul>\n

    The welding fume suction torch must of course be connected via a 50 mm diameter hose to a portable or fixed suction system that creates a vacuum to capture the fumes through the torch.<\/td>\n
