General Safety
(Continued)
! WARNING
Do not breathe fumes that are produced by the arc welding operation. These
fumes are dangerous. If the welding area cannot be adequately ventilated, be sure to use an air supplied respirator.
●Keep the head and face out of the welding fumes.
●Do not perform electric arc welding operations on metals that are galvanized or cadmium plated, or contain zinc, mercury, or beryllium without completing the following precautions:
a.Remove the coating from the base metal.
b.Make sure that the welding area is well ventilated.
c.Use an
Extremely toxic fumes are created when these metals are heated.
! WARNING
The electromagnetic 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 arc welding operations.
●Route the wire gun and work cables together and secure with tape when possible.
●Never wrap arc welder cables around the body.
●Always position the wire gun and work leads so that they are on the same side of the body.
●Exposure to electromagnetic fields during welding may have other health effects which are not known.
Always be sure
! WARNING that the welding area is secure and free of hazards (sparks, flames, glowing metal or slag) prior to leaving. Be sure that equipment 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.
!DANGER
Cylinders can explode if damaged. Shielding 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 arcs.
●Install and secure cylinders in an upright position by chaining them to stationary support or equipment cylinder rack to prevent 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; maintain 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 publication
Never use
!DANGER flammable gasses 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 the arc welder.
●For best results locate the welder in an environment that is clean and dry. Dust and dirt in the welder retain moisture and increase wear of moving parts.
●Place the welder in an area that provides at least 12” (30,48 cm) of ventilation space at both the front and rear of the unit. Keep all obstructions away from this ventilation space.
●Store wire in a clean, dry location with low humidity to preserve the wire coating.
●The receptacle used for the welder must be properly grounded and the welder must be the only load on the power supply circuit. Refer to the Circuit Amps chart on page 1 for correct circuit capacity.
●The use of an extension cord is not recommended for electric arc welding machines. The voltage drop in the extension cord may signifi- cantly degrade the performance of the welder.
