By “standard liter”, we mean 1 liter of a gas under standard conditions:
-
temperature = 0 °C (32°F)
-
pressure = 1 bar (14,50 psi.)
NOTE!
The indicated shielding-gas flow-rate may deviate slightly from the
actual flow-rate if another type of shielding gas is being used instead of the
specified gas mixture (CO2 / Ar / Corgon 18).
WARNING!
If the wirefeeder and the gas hoses are under excessive pressure,
there is a risk of damage to hearing, and of damage to the wirefeeder and the
shielding-gas hoses. Never connect the wirefeeder (i.e. the interconnecting cable)
to the gas cylinder without a pressure regulator. The gasflow regulator is no
substitute for a pressure regulator on the gas cylinder!
For your own safety, and to ensure that the gasflow regulator functions correctly,
proceed as follows:
1.
Close the pressure regulator valve on the gas cylinder
2.
Open the gasflow regulator to the maximum position
WARNING!
An electric shock can be fatal. There is also a risk of injury from
welding wire emerging at speed from the torch. As soon as the gas-flow has been
started when you press the torch trigger, the welding wire is live. Make sure that
from this moment on, the wire does not touch any persons or electrically conduct-
ing or grounded (earthed) parts such as the workpiece, etc. At the same time, the
wirefeed is also started when you press the torch trigger:
- Hold the torch so that it points away from your face and body.
- Never point the welding torch at people, or at objects that you do not intend to
weld
