Buildup Of Gas Can Injure Or Kill; Cylinders Can Explode If Damaged - Eastwood MP250i Instructions Manual

• Set up a clean will lit work area.
• Prepare the parts to be welded by cleaning the weld joint area of any rust, dirt, grease, or paint.
• Select the proper electrode for the weld joint.
• Turn on the Welder and select the appropriate amperage. To determine proper amperage it is best to practice on some similar metals to set up the
machine before welding on an actual part of value.
• Attach the ground clamp to a clean bare metal section on the work piece.
• Insert the electrode into the electrode holder being careful not to allow the electrode to contact the grounded area.
• To start welding an arc must be struck, to do this a motion similar to striking a match will have to be performed with the electrode. Slowly bring the
electrode closer to the weld joint and then contact and drag the electrode across the piece to strike the arc. Once the arc has been stuck you can continue
feeding the electrode into the weld joint.
• While moving along the weld joint the electrode will burn down, while it is burning you will need to continue moving the electrode closer to the joint trying
to keep a 1/8" gap between the end of the electrode and the weld joint. The electrode holder must be held so that the electrode is in a downward angle
moving in the direction of the weld joint.
• To stop welding simply lift the electrode away from the work piece. When finished welding remove the electrode from the holder and turn off the Welder.
SET UP AND OPERATION FOR TIG WELDING
SHIELDING GAS CONNECTION FOR TIG TORCH

BUILDUP OF GAS CAN INJURE OR KILL!

• Shut off gas supply when not in use.
• Ensure adequate ventilation
• Do not weld in confined areas.
• 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.
A Shielding Gas Bottle is NOT INCLUDED with your Eastwood MP250i TIG Torch Kit but is necessary for TIG welding. A Shielding Gas Bottle can be bought at
most local Welding Supply Stores. Eastwood recommends the use of 100% Argon shielding gas when TIG welding Steel and Stainless Steel.
After connecting your Shielding Gas Regulator, (NOT INCLUDED, Eastwood #12238 recommended) the gas flow rate needs to be adjusted so that the proper
amount of Shielding Gas is flowing over your weld. If there is too little gas flow there will be porosity in your welds as well as excessive spatter, if there is too
much gas flow you will be wasting gas and may affect the weld quality.
• Place the Shielding Gas Bottle (NOT INCLUDED) on the Rear Wheel/Tray Assembly and secure it with the Upper and Lower Chains.
• Remove the cap from the Shielding Gas Bottle.
• Insert the large brass Male Fitting on the Shielding Gas Regulator (NOT INCLUDED, Eastwood #12238 recommended) into the Female Fitting on the
Shielding Gas Bottle.
• Tighten the fitting with a wrench till snug, do not over tighten.
• Connect the Male Fitting of the Shielding Gas Inflow Line of the TIG Torch Assembly to the Female Fitting on the Gas Shielding Regulator.
• Tighten the fitting with a wrench till snug, do not over tighten.
