Measuring Torch Gas Flows - ESAB PT-37 Manuel D'instruction

SECTION 5 MAINTENANCE

5.4 Measuring Torch gas Flows

If low gas flow is suspected of causing poor cutting performance or short
consumable life, the flow can be checked by using the Plasma Torch Flow
Measuring Kit. The kit includes a hand held rotameter (flowmeter) which
will indicate the gas flow rate exiting the torch. The kit also includes a set
of instructions which should be followed exactly to insure safe and accu-
rate use of the rotameter.
Total air flow rate in the PT-37 should be 475 cfh (13.4 cmh) minimum with
Flow Measuring Kit
100 amp consumables installed.
