The following installing instructions are valid for most of the gas flow regulator types:
1.
Step aside and open the cylinder valve (A) for a while to blow out possible impurities
from the cylinder valve.
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 cylinder 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 the hose with the regulator and the other end with the wire feed unit. Tighten
the jacket nut.
7.
Open cylinder valve slowly. Gas cylinder pressure meter (F) shows the cylinder pressure.
Note! Do not use the whole contents of the cylinder. The cylinder should be filled when
the cylinder 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 in switched on and
the gun switch pressed simultaneously.
Close cylinder valve after having finished welding. If the machine will be out of use for a long
time, unscrew the pressure regulation screw.
3.10 Main switch I/O
When you turn the main switch of the FastMig power source into I-position, the pilot lamp
closest to this switch will light up, indicating the power source is ready for welding.
NOTE!
Always start and switch off the machine with the main switch, never use the mains plug as a
switch.
