Mig Shielding Gas Flow Adjustment; Mig Welding - Eastwood MP200i Assembly And Operating Instructions Manual

MIG SHIELDING GAS FLOW ADJUSTMENT

After connecting the Shielding Gas Regulator, the gas flow rate needs to be adjusted so that the proper amount of Shielding Gas is flowing over the weld.
If there is too little gas flow, there will be porosity in the resulting welds as well as excessive spatter.
If there is too much gas flow, this will be wasting gas and may affect the weld quality. The included Regulator has 2 gauges on it; the gauge on the left is
Flow Rate while the gauge on the right is Tank Pressure.
ELECTRIC SHOCK CAN CAUSE INJURY OR DEATH!
This procedure requires that the Welder power be switched on. DO NOT make contact with the wire when the MIG Gun Trigger
is depressed.
• Open the MIG Shielding Gas tank valve all the way.
• Adjust the knob on the Pressure Regulator to ~30 CFH.
• After the Welder is turned on and set to MIG mode, the Trigger of the MIG Gun (or Spool Gun) will control the internal gas flow.
• As the MIG Gun is triggered, the Gas Flow needle will drop to a steady reading. This is the value to be used for measuring Gas Flow.
• The Gas Flow should ideally be set to ~20 CFH while flowing. The CFH (Cubic Feet per Hour) scale is the inside scale in red on the Flow Gauge. 20 CFH is
the most typical flow rate but it may need to be adjusted in some cases depending on if there is a slight breeze or some other instance where additional
shielding gas is required to prevent porosity in the weld.
• When finished welding, the Valve on the Gas Bottle must be closed.

MIG WELDING

ELECTRIC SHOCK CAN CAUSE INJURY OR DEATH!
• Improper use of an electric Welder can cause electric shock, injury and death! Read all precautions described in the Welder Manual
to reduce the possibility of electric shock.
• Disconnect Welder from power supply before assembly, disassembly or maintenance of the MIG Gun, Contact Tip and when
installing or removing Nozzles.
• Always wear dry, protective clothing and leather welding gloves and insulated footwear. Use suitable clothing made from durable
flame-resistant material to protect your skin.
• Always operate the Welder in a clean, dry, well ventilated area. Do not operate the Welder in humid, wet, rainy or poorly ventilated
areas.
• The electrode and work (or ground) circuits are electrically "hot" when the Welder is on. Do not allow these "hot" parts to come
in contact with bare skin or wet clothing.
• Separate yourself from the welding circuit by using insulating mats to prevent contact from the work surface.
• Be sure that the work piece is properly supported and grounded prior to beginning an electric welding operation.
The Eastwood Elite AC/DC MP200i can be used to form a large number of 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. Welding, as with any skill, requires a learning curve to achieve
proficiency. An extended period of "Trial and Error" performed on scrap material is required before welding on an actual project can begin.
This machine has smart wire feeding technology to prevent forcing excessive wire into the start of the weld. When the machine is not
welding and feeding wire, it will feed wire at a slow fixed speed for approximately five seconds, and then speed up to max speed. This is
to quickly feed wire through the torch. Once the machine senses that it is welding it will automatically run at the preset wire speed that
the user has set on the machine. Do not be alarmed when the wire feeds slowly while not welding.
• Refer to the Suggested Settings Chart which is located on the inside of the Side Panel Door of the Eastwood Welder. It is also located towards the end of
this manual, see DATA CHART (FIG 26). From the chart select the baseline starting point for the recommended settings described in the chart.
• Connect your ground clamp to the workpieces 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 welding area as possible.
• Assess the general work area and make sure the welding area is also cleaned of any paint, grease, rust, oils, etc.
• Plug in the Welder and move switch to the ON position.
• The Welder must be set to MIG mode by pressing the Mode Selection Button [6] and configured for the type of welding you are performing.
