DESCRIPTION: Single-stage cylinder regulators RB . . . -3-z are lever-less regulators with variable outlet pressure control. These regulators reduce the pressure of gases taken from the cylinder to the required outlet (working) pressure and ensure that this pressure is automatically maintained at as constant a level as possible irrespective of changes in inlet pressure.
APPLICATION: The RB . . . -3-z reducers are used for all common welding tasks: welding of sheet metal up to 20 mm thick, cutting of sheet metal up to 200 mm thick and other processes such as heating, soldering, tanning, etc. All reducers can be used for various industrial processes if the requirements are complied with.
THE COMPOSITION OF THE SET: The reducer set includes: reducer according to table 1 piece, spare gasket (ring) 2 pieces, package: cardboard box 1 piece.
