2.1 gENErAl
Electric shock can kill! Ensure the line
(wall) disconnect switch or circuit
breaker is open before attempting any
inspection or work on the inside of
the plumbing box. Always wear safety
goggles with side shields when blowing
out the plumbing box with low pressure air.
Maintenance work must be performed by an experienced
person. Do not permit untrained persons to inspect,
clean, or lubricate this equipment.
On a regular basis, check cylinder valves, regulators, hoses,
and gas connections for leaks using a soap solution or a
leak test solution.
Keep the plumbing box dry, free of oil and grease, and
protected at all times from damage by hot metal and
sparks.
Refer to F-15-116 (Esab Smart Plasma 1000 system) for
operational details and process troubleshooting.
2.2 clEANiNg
Periodically, remove the cover from the plumbing box
and, wearing proper eye protection, blow accumulated
dust and dirt from the air passages and the interior com-
ponents using clean low-pressure air. It is imperative that
the air passages to the interior of the unit be kept free of
dirt accumulation to ensure adequate circulation of cool-
ing air.
The length of time between cleaning will depend on the
location of the unit and the amount of dust in the atmo-
sphere.
After cleaning with low-pressure air, check for and tighten
any loose hardware, including all electrical connections.
Check for frayed and/or cracked insulation on all power
cables and replace if necessary.
Electric shock can kill! Failure to replace
worn or damaged cables may result
in a bare cable touching a grounded
surface. The resulting electrical arc may
damage the unprotected eyes and will
present a serious fire hazard. Bodily
contact with a bare cable, connector, or conductor
may ressult in severe electrical shock, causing serious
burns or death.
