Installation

Gas Cylinder (MIG)
CAUTION • The cylinder platform, chains or any
other type of support shall not damage or put in risk the
valve or gas cylinder. Cylinders can explode if damaged.
• The cylinder platform (A) accommodates small or
medium cylinders up to 1 m tall.
• Set the gas cylinder onto the platform and secure with
the chain (B).
CAUTION
• Be aware of all the indications and
safety warnings in this Manual when carrying out
connections.
• Purge the cylinder as indicated in page 6, in the "Use of
Compressed Gas Cylinder" item.
• CO cylinders have valves that can be screwed directly to
2
the regulators. The Argon gas o Argon mix cylinders need
an adapter with round tip (C) to connect a regulator.
• Tighten the regulator connection to the cylinder valve
using a wrench.

Gas Connection (MIG)
• Connect the end of the hose into the regulator (D) outlet
and the other end into the welder (E) gas inlet. Tighten
both connections to make sure the system is well sealed.
• Before opening the cylinder valve, close the regulator
valve turning in a counterclockwise direction. When
opening the cylinder valve, double check the regulator is
not pointing towards you.
• Set the regulator flow rate to 5 L/min - 8 L/min. The flow
rate depends on the material to be welded and the
presence of wind gusts that could alter the gas flow.
• To weld steel low in carbon and most of the jobs, CO
used, even though the process expels a lot of projectiles.
• CO mixed with argon reduce the projectiles during the
2
job.
• To weld aluminum, use Argon gas.

can be used with or without gas depending on the
requirements of the job or the type of wire used:
• Solid wire (GMAW). Gas is required to protect the electric
arc.
• Wire with Flux core (FCAW). Gas is not required as the
combustion of the wire core generates the necessary gases
to protect the electric arc.
