NOTE
Correct adjustment will result in the wire reel
circumference continuing no further than
20mm after release of the MIG Torch trigger
switch. The wire should be slack without be-
coming dislodged from the reel.
3.20 Shielding Gas Regulator Operating
Instructions
!
WARNING
This equipment is designed for use with weld-
ing grade (Inert) shielding gases only.
NOTE
Shielding Gas Regulator not included in the
Transmig 2RT.
NOTE
Shielding Gas is not required if the unit is
used with self shielded FCAW (flux cored arc
welding) wires.
Shielding Gas Regulator Safety
This regulator is designed to reduce and control high
pressure gas from a cylinder or pipeline to the working
pressure required for the equipment using it.
If the equipment is improperly used, hazardous
conditions are created that may cause accidents. It is
the users responsibility to prevent such conditions.
Before handing or using the equipment, understand and
comply at all times with the safe practices prescribed in
this instruction.
SPECIFIC PROCEDURES for the use of regulators are
listed below.
1. NEVER subject the regulator to inlet pressure
greater than its rated inlet pressure.
2. NEVER pressurize a regulator that has loose or
damaged parts or is in a questionable condition.
NEVER loosen a connection or attempt to remove
any part of a regulator until the gas pressure has
been relieved. Under pressure, gas can danger-
ously propel a loose part.
3. DO NOT remove the regulator from a cylinder
without first closing the cylinder valve and releas-
ing gas in the regulator high and low pressure
chambers.
4. DO NOT use the regulator as a control valve. When
downstream equipment is not in use for extended
periods of time, shut off the gas at the cylinder
valve and release the gas from the equipment.
5. OPEN the cylinder valve SLOWLY. Close after use.
User Responsibilities
This equipment will perform safely and reliable only when
installed, operated, maintained, and repaired in accor-
dance with the instructions provided. Equipment must be
checked periodically and repaired, replaced, or reset as
necessary for continued safe and reliable performance.
Defective equipment should not be used. Parts that are
broken, missing, obviously worn, distorted, or contami-
nated should be replaced immediately.
The user of this equipment will generally have the sole
responsibility for any malfunction, which results from
improper use, faulty maintenance, or by repair by anyone
other than an accredited repairer.
CAUTION
Match regulator to cylinder. NEVER CONNECT
a regulator designed for a particular gas or
gases to a cylinder containing any other gas.

NOTE
The regulator/flow meters used with argon
based and carbon dioxide shielding gases are
different. The regulator/flow meter supplied
with certain Transmig 250i welders is for argon
based shielding gases. If carbon dioxide is to
be used a suitable carbon dioxide regulator/
flow meter will need to be fitted.
