2.10. SHIELD GAS

Handle gas bottle with care. There is a risk for injury if gas bottle or bottle valve

is damaged!

Argon, argon-helium or helium gases are normally used as shield gas. Check that the gas bottle

valve is suitable for the gas. The ﬂow rate is set according to the welding power used in the job.

A suitable ﬂow rate is normally 8 - 10 l/min. If the gas ﬂow is not suitable, the welded joint will

be sporous. Contact your local Kemppi-dealer for choosing gas and equipment.

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 simultaniously.
Close bottle valve after having ﬁnished welding. If the machine will be out of use for a long

time, unscrew the pressure regulation screw.

2.10.1. Installing gas bottle

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.
