5.01 Shielding Gas Regulator/Flowmeter Operating Instructions
!!
WARNING
This equipment is designed for use with welding grade (Inert) shielding gases only..
Shielding Gas Connection
The CutSkill Preset Argon Regulator / Flowmeter and Gas Hose Kit is an optional accessory. Connect the gas
regulator onto the gas cylinder/bottle by hand, keeping the round sight gauge in the vertical position. Then
tighten the nut with a spanner, but do-not over tighten. Connect the gas hose to the threaded outlet on the
right-hand side of the regulator (Picture A) and tighten with a spanner. Connect the other end of the gas hose
to gas inlet fitting on the rear panel of the welding machine using the supplied Adjustable Hose Clamp to tighten
up the hose onto the barb-connector. Check for any leaks with soapy water in a squeeze bottle, and look for
bubbles (when the gas is on), this will highlight any gas leaks.
The gas flow (in Litres Per Minute) for shielding the molten weld metal from the atmosphere is adjustable
and depends on the job and atmospheric conditions you encounter when welding. As a general rule for MIG
Welding, always use a minimum of 12 LPM when welding with an amperage range of under 100Amps, a min.
of 15 LPM when the amperage is under 180Amps and a minimum of 18 LPM for welding amperages over
200Amps. A lower gas flow will affect the welding quality and cause a porous weld while high gas flow results
in bigger consumption of gas.
The flow rate is measured at the middle of the float ball.

Shielding Gas Regulator/Flowmeter Safety
This regulator/flowmeter is designed to reduce and control high pressure gas from a cylinder or pipeline to
the working pressure required for the equipment using it.
If the equipment is improperly used, hazardous conditions are created that may cause accidents. It is the users
responsibility 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 an 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.
