NOTE!
Always fasten gas bottle properly in vertical position in a special holder on the wall or on a
carriage. Remember to close gas bottle valve after having finished welding.
The following installation instructions are valid for most gas flow regulator types:
1.
Step aside and open the bottle valve (A) for a while to blow out possible impurities from the
bottle valve. Note! Watch out for the gas flow.
2.
Turn the press regulation screw (B) of the regulator until no spring pressure can be felt.
3.
Close needle valve if there is one in the regulator.
4.
Install the regulator on bottle valve and tighten connecting nut (C) with a wrench.
5.
Install hose spindle (D) and jacket nut (E) into gas hose and tighten with hose clamp.
6.
Connect one end of the hose with the regulator and the other end with the power source.
Tighten the jacket nut.
7.
Open bottle valve slowly. Gas bottle pressure meter (F) shows the bottle pressure. Note! Do
not use the whole contents of the bottle. The bottle should be filled when the bottle
pressure is 2 bar.
8.
Open needle valve if there is one in the regulator.
9.
Turn regulation screw (B) until hose pressure meter (G) shows the required flow (or pressure).
When regulating flow amount, the power source should be switched on and the gun
switch pressed simultaneously.
Close bottle valve after having finished welding. If the machine will be out of use for a long
time, unscrew the pressure regulation screw.
