HOT METAL AND TOOLS WILL BURN!
•
Electric welding heats metal and tools to temperatures that will cause severe burns!
•
Use protective, heat resistant gloves and clothing when using Eastwood or any other welding equipment. Never touch welded work
surface, torch tip or nozzle until they have completely cooled.
FLYING METAL CHIPS CAN CAUSE INJURY!
•
Grinding and sanding will eject metal chips, dust, debris and sparks at high velocity. To prevent eye injury wear approved safety
glasses.
•
Wear an OSHA-approved respirator when grinding or sanding.
•
Read all manuals included with specific grinders, sanders or other power tools used before and after the welding process. Be aware
of all power tool safety warnings.
INADEQUATE WIRING CAN CAUSE FIRE AND INJURY!
•
Verify that the facility power source has properly rated wiring to handle power requirements of this Welder.
Your Eastwood MP140i can be used to form many different joints and welds all of which will require practice and testing before using on an actual project piece.
This following welding process is just a baseline to get you started.
• Refer to the ‘Suggested Settings’ chart which is located inside the side door of your Eastwood Welder. From the chart select your baseline starting point
for the recommended settings described in the chart.
• Connect your ground clamp to the work pieces that are to be welded. Make sure the ground clamp contacts are placed on a clean piece of metal free of
paint, grease, rust, oils, etc. It is recommended to place your ground clamp as close to the weld area as possible.
• Assess your weld area and make sure the welding area is also cleaned of any paint, grease, rust, oils, etc.
• Plug in the Welder and move the Power Switch at the Upper Rear Panel to the “ON” position Depress the Welding Gun trigger pointing the welding gun
away from your body and then let go of the trigger and cut the wire back to ~1/4” stick out length.
• Wearing your welding helmet, gloves, and long sleeve shirt and pants, put the end of the wire sticking out of the gun into the joint to be welded.
• Position the MIG Gun so that it is perpendicular to the base metal with ~20° tilt back.
• Depress the trigger to start the wire feed which starts the arc.
NOTE:
A push, perpendicular, or drag technique can be used to weld the pieces together; the type used depends on the type of joint as well as other
influential conditions.
• Once you depress the trigger and the arc has started, you will notice a molten puddle will form; this puddle is the weld bead and will follow the motion of
the MIG Gun. Watching the size of the puddle dictates how fast you should be moving with the torch. If you burn through the material you are either moving
to slow or you need to make some setting adjustments to the Welder settings. If you’re not penetrating the base metal you’re either moving too fast or you
need to make adjustments to the Welder settings.
• Release the trigger on the MIG Gun to stop the weld.
• After welding is complete, turn off the Welder and disconnect from power source.
