Straight answers to the questions people ask most when choosing hose tube extraction arms for welding fume.
It is a flexible extraction arm made from a hose supported by a frame or joints, ending in a hood that you position close to the welding fume. The fan draws fume through the hood and hose to a filter or to the outside.They suit general fabrication and workshops where the arm needs to be moved around. Check the data plate and manual for the arm's size, reach and stated use before choosing.
Flexible arms use a hose that bends and can be moved freely, while rigid tube arms use stiff sections joined by swivel joints. The type of construction affects how well the arm holds its position, how smooth the airflow path is and how it stands up to wear.Which suits you depends on how often the hood is moved, how rough the workplace is and the heat and spatter around the weld. Read the maker's description of the arm and its stated use, and check the data plate and manual for your own equipment.
Choose a length that reaches the work position without being stretched to its limit or left in a long loose loop. Longer arms give more reach but lose more airflow in the hose and are harder to hold in position.Measure the distance from the mounting point to the furthest weld position and consider whether the arm will reach all the places you weld.
Hanging models are mounted overhead, for example on a ceiling or rail, leaving the floor clear. Wall models fix to a wall or column, and standing models sit on a base or mobile unit.Choose according to your layout and how the arm will be used, and make sure the mounting point can carry the arm's weight.
As close as practical without getting in the way, because fume capture falls off quickly with distance. Place the hood to the side of or slightly above the weld so that fume is drawn away from the welder's face rather than across it.Strong draughts can pull fume out of the hood's reach, so shield the work area from cross-breezes where possible. Reposition the hood as the work moves, and follow the guidance in the manual for your own arm.
The arm's connection size must match the fan or unit, and the fan needs to supply enough airflow for the arm. Arms made as part of a system are the easiest to match.Check the connection diameter and the airflow recommended for the arm. If you are unsure, our team can help you match the parts.
