Gas Selection For Stainless Steel Welding The best shielding gas for stainless steel welding is a mixture of 90% Helium, 7.5% Argon, and 2.5% Carbon Dioxide. However, 100% Argon can also be used, but an increase in the area being heated by the arc will be experienced causing slightly greater distortion of the base metal.

Gas Selection For Steel Welding With Silicon Bronze Wire

Use only pure Argon when welding steel with Silicon-Bronze wire.

INSTALL THE SHIELDING GAS

WARNING

IMPROPER HANDLING AND MAINTE-

NANCE OF COMPRESSED GAS CYLIN-

DERS AND REGULATORS CAN RESULT

IN SERIOUS INJURY OR DEATH! Always secure gas cylinders to the welding cart, a wall, or other fixed support to prevent the

cylinder from falling o_er and rupturing.

Read, understand, and follow all the COM-

PRESSED GASSES AND EQUIPMENT

HAZARDS in the SAFETY SUMMARY at the front of this manual. Secure your gas cylin- der to the welding cart, or other fixed sup-

port.

1.Remove the protective cap from the cylin- der and inspect the regulator connecting threads for dust, dirt, oil, and grease. Remove any dust or dirt with a clean cloth. DO NOT ATTACH YOUR REGULA-

TOR IF OIL, GREASE, OR DAMAGE ARE PRESENT.

2.Open the cylinder valve FOR JUST AN INSTANT to blow out any foreign matter inside the valve port. Never aim the open valve cylinder port at yourself or bystanders.

3.Screw the regulator into the cylinder valve and tighten with a wrench.

4.Firmly push the gas hose over barbed fit- tings on back of welder and regulator.

5.Secure both ends of hose onto barbed fit- tings with hose clamps.

CHECK THE GAS FLOW

WARNING

IMPROPER HANDLING AND MAINTENANCE OF COMPRESSED GAS CYLINDERS AND REGULATORS CAN RESULT IN SERIOUS INJURY OR DEATH. To reduce the risk of injury or death, always stand to the side of the cylinder opposite the regulator when opening the cylinder valve, keeping the cylinder valve between you and the regulator. Never aim the open cylinder valve port at yourself or bystanders. Failure to comply with this warning could result in serious personal injury.

Note: If the cylinder you have is equipped with male regulator connecting threads instead of female, you will need to obtain a special compressed gas cylinder adaptor from your gas supplier to install between your gas cylinder and regulator.

-The gas control function does not require the welder to be turned on or plugged in.

-To avoid damage to your regulator, make sure you have the regulator valve closed before opening the cylinder valve.

1.Slowly crack open the cylinder valve, then turn open ALL THE WAY.

2.Pull the trigger on the gun to allow the gas to flow. KEEP THE TRIGGER PULLED. Listen and feel for gas flowing from the end of the welding gun. If your regulator has no adjustment, it has been preset at the factory for a flow of 20 cubic feet per hour. If your gas regulator has an adjustment to control the gas flow rate, turn the adjustment key clockwise to increase gas flow; counterclockwise to reduce flow. For most welding, the gas flow should be set at 15-20 cubic feet per hour. If no gas is heard or felt, verify all steps involved in connecting the gas.

3.Release the trigger.

Note: If welding outside or in a draft, it may become necessary to set up a wind break to keep the shielding gas from being blown from the weld area.
