INSTALLING THE MIG & TIG SHIELDING GAS SUPPLIES
NOTE: The following steps cover the installation of the Shielding Gas Valves, Hoses and Tanks (not included). For flow adjustment, see MIG SHIELDING GAS
FLOW ADJUSTMENT and TIG SHIELDING GAS FLOW ADJUSTMENT .
BUILDUP OF GAS CAN INJURE OR KILL!
• Shut off shielding gas supply when not in use.
•
Always ventilate confined spaces or use approved air-supplied respirator.
•
Always turn your face away from valve outlet when opening cylinder valve.
CYLINDERS CAN EXPLODE IF DAMAGED!
Shielding gas cylinders contain gas under high pressure. If damaged, a cylinder can explode. As gas cylinders are a normal
component of the welding process, use extra care to handle them carefully.
• Protect compressed gas cylinders from excessive heat, mechanical shocks, physical damage, slag, open flames, sparks, and arcs.
Keep away from any welding or other electrical circuits.
•
Install cylinders in an upright position by securing to a specifically designed rack, cart, or stationary support to prevent falling
or tipping over.
• Never weld on a pressurized cylinder or explosion will occur.
•
Use only correct shielding gas cylinders, regulators, hoses, and fittings designed for the specific application; maintain them
and all related components in good condition.
•
Keep protective cap in place over valve except when cylinder is in use.
• Use proper equipment, procedures and have adequate help when moving or lifting cylinders.
UNSECURED BOTTLES CAN INJURE!
•
The integral bottle rack on the Eastwood Elite AC/DC MP200i is not capable of securing welding gas bottles larger than 125CF.
If a larger bottle is being used it must be secured separately. Use proper equipment, procedures and have adequate help when
moving or lifting cylinders.
Shielding Gas Bottles are NOT INCLUDED with the Eastwood Elite AC/DC MP200i but are necessary to MIG and TIG welding. They can be bought at most local
Welding Supply Stores. The Eastwood Elite AC/DC MP200i is capable of securing up to two 40CF - 125CF welding gas cylinders. Eastwood recommends the use
of 75% Argon / 25% CO2 when MIG welding steel, 100% Argon for Aluminum, and Tri-Mix (90% He / 7.5% Ar / 2.5% CO2) for Stainless Steel. 100% Argon is
recommended for all TIG welding applications.
• Place the Shielding Gas Tanks on the Rear Tray
[B]
of the MP200i and mount them securely with the included Gas Cylinder Chains
[ee]
.
• Remove the caps from the Shielding Gas Bottles.
• Insert the large male fitting on the Gas Flowmeters (CO2/Argon)
[M] into the female fittings on the Shielding Gas Bottles (not included).
• Tighten the fittings with a wrench until snug, do not over tighten
(FIG 9)
.
• Connect either end of the Shielding Gas Hoses [E] included with the Eastwood
Elite AC/DC MP200i to the fitting on the Regulators and wrench tighten until
snug
(FIG 9) .
• Connect the other end of the gas lines to the appropriate MIG and TIG fittings
on the rear of the Eastwood Elite AC/DC MP200i and wrench tighten until
snug
(FIG 8)
.
• Check the gas lines for leaks by slowly opening the valves on the gas bottles.
When welding the valves on the bottles should always be fully open. Close them
when done welding to avoid loss of gas.
FIG. 9 FIG. 9
Do not use White Thread Sealing Tape on these connections as it is an inert spherical gas fitting and does not require it.
If you have a leak check for burrs or dirt in the threads or on the spherical joints.
