INSTALLING SHIELDING GAS SUPPLY
A Shielding Gas Bottle is not included with your Eastwood MIG135 but is necessary to use when welding using Solid MIG Wire. A Shielding
Gas Bottle can be rented at most local Welding Supply Stores. Eastwood recommends the use of 75% Argon / 25% CO2 for shielding gas
when MIG welding Steel, and Tri-Mix (90% He / 7.5% Ar / 2.5% CO2) for Stainless Steel.
1. Place the Eastwood MIG135 in its dedicated area or on a welding cart.
2. Secure your Shielding Gas Bottle to a stationary object or mount to your
welding cart if it is equipped to hold one so that the cylinder cannot fall over.
3. Remove the cap from the Shielding Gas Bottle.
4. Insert the large brass male fi tting on the Shielding Gas Regulator into the
female fi tting on the Shielding Gas Bottle. NOTE: Do not use White Tefl on
Tape on this connection as it is a tapered thread and does not require it, if
you have a leak check for burrs or dirt in the threads. If the leak persists,
use gas type sealing tape.
5. Tighten the fi tting with a wrench till snug, do not over tighten.
6. Connect either end of the Gas Line included with your Eastwood MIG135 to
the fi tting on the regulator and wrench tighten till snug.
7. Connect the other end of the gas line to the fi tting on the rear of the
Eastwood MIG135 and wrench tighten till snug.
8. 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 all the way open.
