3.Be sure the torch and work cable rubber cover- ings are free of cuts and cracks that allow high frequency leakage. Cables with high natural rub- ber content, such as Lincoln Stable-Arc®better resist high frequency leakage than neoprene and other synthetic rubber insulated cables.

4.Keep the torch in good repair and all connections tight to reduce high frequency leakage.

5.The work terminal must be connected to a ground within ten feet of the welder, using one of the fol- lowing methods.

a)A metal underground water pipe in direct con- tact with the earth for ten feet or more.

b)A 3/4” (19mm) galvanized pipe or a 5/8” (16mm) solid galvanized iron, steel or copper rod driven at least eight feet into the ground.

The ground should be securely made and the grounding cable should be as short as possible using cable of the same size as the work cable, or larger. Grounding to the building frame electrical conduit or a long pipe system can result in re-radi- ation, effectively making these members radiating antennas.

6.Keep all panels securely in place.

7.All electrical conductors within 50 ft (15.2m) of the welder should be enclosed in grounded, rigid metallic conduit or equivalent shielding. Flexible metallic conduit is generally not suitable.

8.When the welder is enclosed in a metal building, several earth driven electrical grounds connected (as in 5b above) around the periphery of the build- ing are recommended.

Failure to observe these recommended installation procedures can cause radio or TV interference prob- lems.

INPUT CONNECTIONS

Be sure the voltage, phase, and frequency of the input power is as specified on the rating plate, located on the bottom of the machine.

WARNING

ELECTRIC SHOCK can kill.

• Have a qualified electrician install and service this equipment.

Turn the input power OFF and unplug the machine from the receptacle before working on this equipment.

Allow machine to sit for 5 minutes minimum to allow the power capacitors to discharge before working inside this equipment.

Do not touch electrically hot parts.

Machine must be plugged into a receptacle that is grounded according to the National Electrical Code and local codes.

Do not remove or defeat the purpose of the power cord ground pin.

RECONNECT PROCEDURE

The Invertec V205-T DC & V205-T AC/DC auto recon- nect to either 115V or 230V supply.

This machine is capable of operating within the follow- ing input voltage ranges (Table A.1):

RANGE

115V

 

90-140V

208V / 230V

 

184-276V

 

 

 

Fuse the input circuit with time delay fuses or delay type¹ circuit breakers. Using fuses or circuit breakers smaller than recommended may result in “nuisance” shut-offs from welder inrush currents even if not weld- ing at high currents.

The Invertec Power Source is recommended for use on an individual branch circuit.

¹Also called “inverse time” or “thermal/magnetic” circuit breakers. These circuit breakers have a delay in tripping action that decreases as the magnitude of the current increases.
