Page 3: Electric Shock Can Kill
Take all precautions described in this manual to reduce the possibility of electric shock. The Alpha Mig 140 power switch is to be in the OFF ("0") position when installing work cable and gun and when connecting power cord to input power. - Page 4 is on. De not touch these "hot" parts with your bare or wet clothing. Ground the work or metal to be welded to a good electrical (earth) ground. FUMES AND GASES can be dangerous. Do not breathe fumes that are produced by the arc welding operation. These fumes are dangerous.
- Page 5 ELECTRIC AND MANGETIC FIELDS may be dangerous The electric magnetic field that is generated during arc welding may interfere with the operation of various electrical and electronic devices such as cardiac pacemakers. Persons using such devices should consult with their physician prior to performing any electric welding operations. Exposure to electromagnetic fields during welding may have other health effects which are not known.

5. Reinstall by putting back the wire drive roll and tighten the hex bolt. Welding Wire Installation Your Alpha Mig 140 welding machine can use both a 8” and 4” diameter spool of wire (the maximum width of the spool can be no more than 2.2” ). There is a plastic tube (2”diameter) attached to the wire drive. - Page 9 Feed the Welding Wire though the Wire Feeder by following the instructions as shown below (Figure D-3) 1. Release the spring tensioned pressure arm① of the wire feeder and lift up the idle roll arm②, verify that the groove size matches that of the wire diameter being used.( see previous chapter describing installation of feed rollers) 2.
