5.1.6. Connection of Shield Gas
Warning!
-
Since the arc of MIG welding is much strong than that of MMA welding, please
wear
welding helmet and protective clothing.
Connect the CO2 hose, which come from the wire feeder to the
copper nozzle of gas bottle. The gas supply system includes the gas
bottle, the air regulator and the gas hose, the heater cable should be
inserted into the socket of machine’s back, and use the hose clamp to
tighten it to prevent leaking or air-in, so that the welding spot is
protected.
Please note
1)
Leakage of shielding gas affects the performance of arc welding.
2)
Avoid the sun shine on the gas cylinder to eliminate the possible
explosion of gas cylinder due to the increasing pressure of gas
resulted from the heat.
3)
It is extremely forbidden to knock at gas cylinder and lay the
cylinder horizontally.
4)
Ensure no person is up against the regulator, before the gas
release or shut the gas output.
5)
For machine with heating power output, insert the power supply
plug of the heater into the 36 VAC (5A) socket on the back panel
of the welding machine. For machine without heating power
output, should use the AC220V heater.
6)
The gas output volume meter should be installed vertically to
ensure the precisely measuring.
Before the installation of gas regulator, release and shut the gas for
several time in order to remove the possible dust on the sieve to avail
the gas output
