INVERTEC V350-PRO For use with machines Code 10651, 10669, 10852 Safety Depends on You Lincoln arc welding and cutting equipment is designed and built with safety in mind. However, your overall safety can be increased by proper installation ... and thought- ful operation on your part.
351040, Miami, Florida 33135 or CSA Standard W117.2-1974. A Free copy of “Arc Welding Safety” booklet E205 is available from the Lincoln Electric Company, 22801 St. Clair Avenue, Cleveland, Ohio 44117-1199. BE SURE THAT ALL INSTALLATION, OPERATION, MAINTENANCE AND REPAIR PROCEDURES ARE PERFORMED ONLY BY QUALIFIED INDIVIDUALS.
ELECTRIC SHOCK can kill. 3.a. The electrode and work (or ground) circuits are electrically “hot” when the welder is on. Do not touch these “hot” parts with your bare skin or wet clothing. Wear dry, hole-free gloves to insulate hands.

WELDING SPARKS can cause fire or explosion. 6.a. Remove fire hazards from the welding area. If this is not possible, cover them to prevent the welding sparks from starting a fire. Remember that welding sparks and hot materials from welding can easily go through small cracks and openings to adjacent areas.

LN-7 Connection Instructions An LN-7 can only be used with the “Factory” & “Advance Process” versions of the 350-Pro. • Turn the Invertec power switch "off". • Connect the K480 control cable from the LN-7 to the 115VAC 14-pin wire feeder MS-style connector on the rear of the Invertec.
PARALLEL OPERATION The V350-Pro are operable in parallel in CC mode. For best results, the currents of each machine should be reasonably well shared. As an example, with two machines set up in parallel for a 400 amp procedure, each machine should be set to deliver approximately 200 amps, not 300 amps from one and 100 amps from the other.
SAFETY PRECAUTIONS WARNING ELECTRIC SHOCK can kill. • Do not touch electrically live parts or electrode with skin or wet clothing. • Insulate yourself from work and ground. • Always wear dry insulating gloves. ------------------------------------------------------------------------ FUMES AND GASES can be danger- ous.
For all versions, these trigger modes can be over-ridden (switched) with the WELD TERMINALS push button. When changed, the unit will power up in the configuration it was in when it was last powered down. 5. THERMAL • This status light indicates when the power source has been driven into thermal overload.

• The Arc Control regulates the relative Slope of the process. Slope dynamically controls the force the arc has to penetrate an open root. At the minimum setting, Arc Control is very soft and is similar to the Stick Soft mode. At the maximum setting, the slope is reduced, the OCV is reduced, and the operator has full control off the arc force required to pene- trate an open root joint.
