Cautions For Installation - ESAB ARC250i Instruction Manual

CAUTIONS FOR INSTALLATION

 Provide a Switch Box for every Welding Power Source, and use designated
fuse
 Tolerance of Power Voltage Variation is  10% of rated input voltage.
a) Installation place
 Install in the place where less moisture and dust exist. Avoid direct sunlight and
rain, and maintain ambient temperature within –10
possible.
 Keep the welding power source at least 20 cm. away from the wall (if any).
 In case of installation of more two units side by side, a distance of more than 20
cm is recommended between the two power sources.
 Use a shield to protect the welding arc in case of excessive air draft.
b) Ventilation
Adequate ventilation is recommended at the place of installation. For
example the following guideline should be followed:
a) In case of the area being more than 300 square meters (per unit), no
ventilation is required, provided the room is not completely airtight.
b) In case of the area being less than 300 square meters and the welding
