Observe the following cautions to prevent fire, explosion, or rupture.
• Remove inflammables so that they will not get spattered.
If they cannot be removed, use the inflammables with
nonflammable covers.
Spatters or hot base metal immediately after welding may result in fire.
• Do not weld near flammable gases.
If arc is generated in a container (for inflammables) in which gasoline or the like is put, the
container may explode.
• Do not make hot base metals immediately after welding close to inflam-
mables.
• Remove inflammables at the hidden side when welding ceiling, floor, or
wall.
Failure to observe this caution may result in fire.
• Tighten and insulate the cable connections.
Imperfect cable connections or imperfect contacting section of the current path at the
base metal such as iron framework may result in fire due to heat generation by current
conduction.
• Connect the cable at the base metal as close to the welding part as pos-
sible.
• Do not weld a gas tube having gas inside or an enclosed tank or pipe.
Welding an enclosed tank or pipe may result in rupture.
• Locate fire extinguishers near the welding site.
