FUMES AND WELDING GASES CAN BE A HEALTH HAZARD!
• Fumes and gasses released during welding are hazardous. Do not breathe fumes that are produced by the welding operation.
Wear an OSHA-approved respirator when welding.
• Always work in a properly ventilated area.
• Never weld coated materials including but not limited to: cadmium plated, galvanized, lead based paints.
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, MIG Gun 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.
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.
• Open the Shielding Gas tank valve all the way.
• Adjust the knob on the Pressure Regulator to ~30 CFH.
• After the Welder is turned on (Described in following section), 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 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.
