The following Lincoln engine drives meet these condi- tions when run in the high idle mode:
Outback 189, Ranger 225, 250, 250LPG, 305G and 305D engine drives.
Vantage 300, 400, 500 and Air Vantage engine drives.
Some engine drives do not meet these conditions (e.g. Miller Bobcats, etc). Operation of the TOMA- HAWK™ 625 is not recommended on engine drives not conforming to these conditions. Such combina- tions may overvoltage the TOMAHAWK™ 625 power source.
GAS INPUT CONNECTIONS
(External Air Supply)
Supply the TOMAHAWK™ 625 with clean com- pressed air or nitrogen.
•Supply pressure must be between 80 psi and 110 psi.
•Flow rate should be approximately 125 - 200 SCFH (80 ±20 L/min).
NOTE: Oil in the air supply to the TOMAHAWK™ 625 can cause severe problems. Use only a clean air supply.
•Compressed gas can be supplied either through the air fitting supplied with the machine or through the
•If compressed air is being used, it is highly recom- mended that an in line filter be installed in the air supply line ahead of the air connection to the TOMA- HAWK™ 625.
•A standard nominal 5 micron in line filter is recom- mended; however, for optimum performance, select a prefilter with a 3 micron absolute rating.
If these filter ratings are unavailable, anything with a rating less than, or equal to, 20 micron would be acceptable to use. In line filter elements will generally filter the air with little restriction to the airflow until the element is about 75% contaminated. After this point, there will be a noticeable pressure drop in the line. Filter elements should be replaced when a pressure drop of
NOTE: When using nitrogen gas from a cylinder, the cylinder must have a pressure regulator.
•Maximum psi from a nitrogen gas cylinder to the TOMAHAWK™ 625 regulator should never exceed 110 psi.
•Install a hose between the nitrogen gas cylin- der regulator and the TOMAHAWK™ 625 gas inlet.

WARNING
CYLINDER could explode if dam- aged.
• Keep cylinder upright and chained to a fixed support.
• Keep cylinder away from areas where it could be damaged.
•Never lift machine with cylinder attached.
•Never allow the cutting torch to touch the cylinder.
•Keep cylinder away from live electrical parts.
•Maximum inlet pressure 110 psi.
OUTPUT CONNECTIONS
Torch
The TOMAHAWK™ 625 is sent from the factory with a cutting torch and work clamp included. The work clamp must be securely connected to the work piece. If the work piece is painted or extremely dirty it may be necessary to expose the bare metal in order to make a good electrical connection.
