3 Installation
CAUTION
• The welder can be moved easily by using the caster. After installation, use the stopper to fix the
welder before starting operations.
3.1 Installation Site and Welder Environment
The welder can be used under the following environmental conditions:
• Dry, indoor and at least 30 cm from the the wall or peripheral devices
• Free from direct sunlight, wind, and rain
• Ambient temperature of -10 to 40℃
• Altitude less than 1000 m
• Free from direct splash of welding spatter or metalic fine powder at grinding
• Humidity up to 90% at 20℃, up to 50% at 40℃ with no condensing
■ Wind Prevention and Ventilation
When the welder is used outside and the wind blows, or when a fan is used, put up a screen
to prevent the arc section from being exposed directly to the wind. Normally, the
allowable wind limit for welding using shielding gas is approx. 1.5 m/s or less. If the
wind speed is higher than this limit, stop operation or take some countermeasures such as
putting up a screen.
At operations indoor or in a container, ventilation is needed. In this case, do not use a fan
to blow the air, but ventilate the accumulated gas by providing a ventilating fan or exhaust
duct. A continuous supply of fresh air is required to prevent suffocation of the workers.
Even for indoor operations, sufficient attention to the shield effect must be paid when using
air tools or fans around the welder.
3.2 Installation Site and Gas Regulator Environment
Handle the gas regulator with special care since it contains high pressure gas. Refer to the
instruction manual attached to the gas regulator.
Use the gas regulator in the specified site free from direct sunlight. If you cannot help
installing at the welding site, fix it vertically to the column or gas regulator stand to prevent
it from falling. Avoid heating by welding arc or the like.
