FLUX FEEDING & RECOVERY SYSTEMThe flux is fed by gravity from the flux delivery hopper mounted on the welding head through a tube into the welding zone. Flux feeding is normally effected through gravity and in some cases by pneumatic feeding systems in automatic machines. The conveyor flux feed tube is also provided with a stop valve to control the flow of the flux. This tube is always kept ahead of the contact tube to ensure adequate supply of flux ahead of the arc.A pressurised system is used for the recovery of the flux. This system sucks the unmelted flux from the weld puddle for reuse. It is important that the flux recovery be carried out after the weld pool has completely solidified.
