Gas Cylinder (MIG)
CAUTION
• Use care not to damage or put at risk
the valve or the gas cylinder. Cylinders may explode if
damaged.
• Set the gas cylinder close to the welder and in a safe
place to prevent it from falling.
CAUTION
• Pay attention and follow all the
indications and warnings in these instructions when
making connections.
• Purge the cylinder as indicated in page 6, in "Gas
Cylinder Handling".
• Cylinders containing CO
be screwed in directly to the gauges. The cylinders
containing Argon gas or Argon gas mix need a rounded tip
adapter (A) to connect the gauge.
• Tighten the gauge connection to the cylinder valve using
a spanner.

Gas Connection (MIG)
• Connect one end of the hose into the gauge outlet (B)
and the other end into the gas inlet in the welder (C).
Tighten both connections to assure the system is perfectly
sealed.
• Before opening the cylinder valve, close the regulator
valve turning counterclockwise. When opening the cylinder
valve, double check the gauge is not pointing towards you.
• Set the gauge flow rate to 1.32 gal/min - 2.11 gal/min
The flow rate depends of the material to be soldered and
wind rates that could alter the gas flow.
• To solder low carbon steel and most of the jobs, use CO
even though it expels a lot of weld spatter.
• CO
mixed with Argon reduces the weld spatters while

working.
• To weld aluminum, use Argon Gas.

the type of micro wire used:
• Solid micro wire (GMAW). Gas is needed to protect the
electric arc.
• Flux core micro wire (FCAW). No gas is required because
the wire core combustion releases the gases necessary to
protect the electric arc.
