If is very important that the valve is tight, since this enables the machine to maintain a
minimum pressure of approx. 0.3 Bar inside the tank, even after several hours. Keep in mind
that when the machine is not working, the tank cools down causing a pressure drop. If for
some reason there is a total lack of pressure, the methyl alcohol contained in the Booster Tank
would be sucked in, thus contaminating the electrolyte.
5.10.4 REPLACING THE VALVE
1) Turn off the welder and remove the pressure gauge or safety cap (Fig.5 # 2).
2) Unscrew the check valve cap (Fig. 4 ; A # 13).
3) Unscrew the threaded disk (Fig. 4; B # 21).
4)
Remove the valve and relevant “O.ring” from the seat.
5)
Install the new valve and relevant “O.ring” (Fig. 4; C # 23, 53).
6) Tighten the threaded disk 21, the check valve cap 13, and safety cap (Fig.1 # 2).
7) Check pressure (sec. 5.10.3).
