General Safety

a. Remove coating from base metal.
b. Make sure welding area is well ventilated.
c. Use an
Extremely toxic fumes are created when these metals are heated.
!WARNING Theelectro-
magnetic field that is gener- ated 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 arc welding operations.
●Route the wire feed gun and work cables together and secure with tape when possible.
●Never wrap arc welder cables around body.
●Always position wire feed gun and work leads so that they are on same side of body.
●Exposure to electromagnetic fields during welding may have other health effects which are not known.
Always be sure that the welding
area is secure and free of hazards (sparks, flames, glowing metal or slag) prior to leaving. Be sure that equip- ment is turned off and excess wire is cut off. Be sure that cables are loosely coiled and out of the way. Be sure that all metal and slag has cooled.
Cylin- ders can
explode if damaged. Shield- ing gas cylinders contain gas under high pressure. If
damaged, a cylinder can explode. Since gas cylinders are normally part of the welding process, be sure to treat them carefully.
● Protect compressed gas cylinders from excessive heat, mechanical shocks, and electric arcs.
● Install and secure cylinders in an upright position by chaining them to stationary support or equipment cylinder rack to prevent them from falling or tipping.
● Keep cylinders away from any welding or other electrical circuits.
●Never allow a welding electrode to touch any cylinder.
●Use only correct shielding gas cylinders, regulators, hoses, and fittings designed for the specific application; keep them and associated parts in good condition.
●Turn face away from valve outlet when opening cylinder valve.
●Keep protective cap in place over valve except when cylinder is in use or connected for use.
●Read and follow instructions on compressed gas cylinders, associated equipment, and CGA (Compressed Gas Association) publication
Never use flammable gases
with MIG welders. Only inert or non- flammable gasses such as carbon dioxide, argon, helium, or mixtures of one or more of these gasses are suitable for MIG welding.
Never lift cylinders
! WARNING off the ground by their valves, caps, or with chains or slings.

Installation
Selecting the proper location can significantly increase performance, reliability and life of arc welder.
●For best results place welder in an environment that is clean and dry. Dust and dirt in the welder retain moisture and increase wear of moving parts.
●Place welder in an area that provides at least 12” (30,48 cm) of ventilation space at both front and rear of unit. Keep all obstructions away from this ventilation space.
●Store wire in a clean, dry location with low humidity to preserve wire coating.
●The receptacle used for welder must be properly grounded and welder must be the only load on power supply circuit.
●The use of an extension cord is not recommended for electric arc welding machines. The voltage drop in extension cord may significantly degrade performance of welder.
