ULTRAFEED VAF-4
4-26 OPERATION Manual 0-5332
NOTE
All grooved Feed Rolls have their wire size or range stamped on the side of the roll. On rolls with different
size grooves, the outer (visible when installed) stamped wire size indicates the groove in use.
WARNING
The welding wire is electrically Hot if it is fed by depressing MIG Gun switch. Electrode contact to work
piece will cause an arc with MIG Gun switch depressed.
4.14 Shielding Gas Regulator/ Flowmeter Operating Instructions
!
WARNING
This equipment is designed for use with welding grade (Inert) shielding gases only.
Shielding Gas Regulator/ Flowmeter Safety
This regulator/ flowmeter is designed to reduce and control high pressure gas from a cylinder or pipeline to the work-
ing pressure required for the equipment using it.
If the equipment is improperly used, hazardous conditions are created that may cause accidents. It is the user's re-
sponsibility to prevent such conditions. Before handing or using the equipment, understand and comply at all times
with the safe practices prescribed in this instruction.
SPECIFIC PROCEDURES for the use of regulators/ flowmeters are listed below.
1. NEVER subject the regulator/ flowmeter to inlet pressure greater than its rated inlet pressure.
2. NEVER pressurize a regulator/ flowmeter that has loose or damaged parts or is in a questionable condition.
NEVER loosen a connection or attempt to remove any part of a regulator/ flowmeter until the gas pressure has
been relieved. Under pressure, gas can dangerously propel a loose part.
3. DO NOT remove the regulator/ flowmeter from a cylinder without first closing the cylinder valve and releasing
gas in the regulator/ flowmeter high and low pressure chambers.
4. DO NOT use the regulator/ flowmeter as a control valve. When downstream equipment is not in use for extended
periods of time, shut off the gas at the cylinder valve and release the gas from the equipment.
5. OPEN the cylinder valve SLOWLY. Close after use.
