Precautions for gas cylinder and gas regulator
To prevent falling of gas cylinder, gas regulator explosion and accident caused by gas, ensure to follow
the instructions below:
1.2.6
Precautions for handling of plastic parts
Front and rear panel of the welding power source is made from polycarbonate resin. To prevent from
electric shock or fire caused by the damage on polycarbonate resin, ensure to follow the instructions
below.
• Use only correct shielding gas cylinders according to the related laws, regulations and
customer's standard.
Gas cylinder contains compressed gas. Wrong operation may cause gas explosion,
resulting in serious physical injury.
• Read and follow instructions on compressed gas cylinders, associated equipment, and
the CGA publication P-1 listed in PRINCIPAL SAFETY STANDARDS.
• Keep the cylinder upright and securely chained to a stationary support or a rack.
Falling or tipping of cylinder may cause serious injury.
In opening the valve of gas cylinder, keep your face away from the gas discharge port.
• Keep protective cap in place over valve except when gas cylinder is in use or connected
for use.
• Do not place the gas cylinder under high temperature.
• Protect compressed gas cylinders from excessive heat, mechanical shock, and arcs.
• Do not set welding torch to the cylinder or touch the cylinder with welding electrode.
• For the gas regulator, make sure to use a device for compressed gas cylinder that
conforms to the specific application of the shielding gas.
Using an inappropriate gas regulator may cause explosion.
• Do not apply external force or shock to the front and rear panels.
Otherwise, damage and malfunction may occur.
• If there is dirt on plastic parts, soak a soft cloth in water, alcohol or neutral detergent,
wring it well and wipe off the dirt.
Do not use organic detergent or chemical agent. Doing so may cause crack (breaking)
and degrade the strength.
• If there is any abnormality in the plastic parts such as front and rear panels,
immediately stop the use and contact your dealer.
• Do not use the welding power source at location in which organic solvent, chemicals,
cutting oil and composition oil adhere or atmosphere containing the above.
Doing so may cause crack (breaking) and deterioration in the plastic part.
