Eastwood MP200i Instructions Manual page 10

A Shielding Gas Bottle is NOT INCLUDED with your Eastwood MP200i but is neces-
sary to weld using Solid Wire. It can be bought at most local Welding Supply Stores.
Eastwood recommends the use of 75% Argon / 25% CO2 for shielding gas when MIG
welding Steel, 100% Argon for Aluminum, and Tri-Mix (90% He / 7.5% Ar / 2.5%
CO2) for Stainless Steel.
• Place the Eastwood MP200i in its dedicated area or on a welding cart.
• Secure your Shielding Gas Bottle to a stationary object or mount to your weld-
ing cart if it is equipped to hold one so that the cylinder cannot fall over.
• Remove the cap from the Shielding Gas Bottle.
• Install the Regulator Knob on the Shielding Gas Regulator (FIG 10).
• Insert the large brass male fitting on the Shielding Gas Regulator into the
female fitting on the Shielding Gas Bottle (FIG 11).
Do not use White Thread Sealing Tape on this connection as
it is an inert gas fitting and does not require it. If you have a
leak, check for burrs or dirt in the threads.
• Tighten the fitting with a wrench until snug, do not over tighten.
• Connect either end of the Gas Line included with your Eastwood MP200i to
the fitting on the regulator and wrench tighten until snug (FIG 11).
• Connect the other end of the gas line to the fitting on the rear of the Eastwood
MP200i and wrench tighten until snug (FIG 12).
• Check the gas line for leaks by slowly opening the valve on the gas bottle.
When welding the valve on the bottle should always be fully open.
