CHANGING THE POLARITY FOR WELDING WITH FLUX CORE WIRE
The Eastwood MP140i comes set up to weld with Solid Wire and Shielding Gas
(FIG 8)
. To use a Flux Cored wire, the Polarity of the short Cable Lead attached

.
• Disconnect the short Cable Lead from the Positive (+) Connection Receptacle
by rotating the Rubber Insulator 1/2 turn Counter-Clockwise and pulling
outward.

INSTALLING THE SHIELDING GAS SUPPLY
• Shut off shielding gas supply when not in use.
• Always ventilate confined spaces or use approved air-supplied respirator.
• Always turn your face away from valve outlet when opening cylinder valve.
• 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 de-
signed 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.

If damaged, a cylinder can explode. As gas cylinders are a
normal component of the welding process, use extra care
to handle them carefully.
