Ground cable
Fasten earthing press of ground cable carefully, preferably direct to welding piece. Contact surface of press always
should be as large as possible.
Clean the fastening surface from paint and rust!
Use in your MIG equipment 70 mm
2
copper-cables. Thinner cross-sectional areas might cause overheating
of connectors and insulations.
Make sure that the welding gun in your use is designed for max. welding current needed by you!
Never use a damaged welding gun!
Shielding gas
As MIG shielding gas is used carbon dioxide, mixed gases and argon. Shielding gas flow rate is defined by welding
current size.
Gas flow regulator
Gas flow regulator should be suitable for shielding gas used by you. The regulator being in your use might be
different from the one in picture, however, following general instructions are valid for all pressure regulators.

Before mounting of flow regulator
Step aside, open cylinder valve (
51)
somewhat for a
moment, in this way you can blow out any dirt that may
be in the valve of bottle.
Screw press regulation screw (
52
) of regulator outwards
so long that no spring pressure can be felt (screw is
turning freely).
Close needle valve (
53
) if there is one in regulator
Connect regulator onto valve of bottle
Tighten connecting nut (
54
) preferably with a wrench.
Put hose spindle (
55
) of regulator with jacket nuts (
56
)
onto gas hose, connection should be ensured with hose
clamp (
57
)
Connect hose onto regulator and machine, tighten jacket
nuts.
Open valve of bottle slowly
Pressure meter (
P1
) shows pressure of bottle. Never use up all the gas in the bottle, send the bottle for filling up
when bottle pressure still is 2 bar.
Open needle valve if there is one in regulator
Screw regulation screw (
52
) inwards until hose pressure meter (
P2
) shows flow (or pressure) required. By
regulation of flow amount the machine has to be in operation and the gun switch should be pressed on at the
same time.
Close valve of bottle always after having stopped welding
If the machine will be unused for a longer time, you should also unscrew pressure regulation screw (
52
).
Gas bottle
The gas bottle may explode if it falls!
Always fasten gas bottle tightly in vertical position, to wall stand or bottle cart, specially designed for it!
For safety reasons always remove gas bottle from transport stand of machine before lifting or car transport of
machine!
