Gas Supplies
Adequate supply is absolutely necessary for
maximum machine performance.
All pipelines and hoses must be clean
and free of oil, combustible particles or
other foreign matter that might cause
performance or combustion problems.
Prior to connecting fuel gas and oxygen
lines to the machine or if the lines have
been disconnected for any reason, the
lines must be purged.
Observe the rules and regulations
contained in Pamphlet 51 published by
the National Fire Protection Association
and all locals ordinances relating to the
