EN3.8 shielding gasAs MIG shielding gas is used carbon dioxide, mixed gases and argon. Shielding gas flow rate isdefined by welding current size. Typical rate of gas in welding of steel is 8-15 l / min.gas flow regulatorGas flow regulator should be suitable for shielding gas used by you. The regulator being inyour use might be different from the one in picture, however, following general instructionsare valid for all pressure regulators.Before mounting of flow regulator1. Step aside and open the bottle valve (A) for a while to blow out possible impurities fromthe bottle 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 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 the hose with the regulator and the other end with the power source. Tightenthe 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 bottlepressure 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 (orpressure). When regulating flow amount, the power source should be switched on andgas test button on the panel pressed simultaniously.Close bottle valve after having finished welding. If the machine will be out of use for a longtime, unscrew the pressure regulation screw.EBDCAFGA. Gas bottle valveB. Pressure regulation screwC. Connecting nutD. Hose spindleE. Jacket nutF.
