The following installing instructions are valid for most of the 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.

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 wire feed unit. 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 in 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.

2.11 MAIN SWITCH I/O

When you turn the main switch of the Kemppi FastMig™ power source into I-position, the pilot

lamp closest to this switch will light up, indicating the power source is ready for welding. The

equipment is returned to the position which it last carried out before the main switch was

turned to zero position.

NOTE!

Always start and switch off the machine with the main switch, never use the mains plug as

a switch.
