warning
At no time should the withdrawal rate of an individual acetylene cylinder exceed
1/7 of the cylinder contents per hour. If additional flow capacity is required, use an
acetylene manifold system of sufficient size to supply the necessary volume.
CaUtion
Always make sure your equipment is rated for the size tip you have selected. A tip
with too much capacity for the equipment can starve or choke the tip. This causes
overheating of the head and a backfire may result. Use only genuine VICTOR
