WELDING OUTPUT CABLES

With the engine off, route the electrode and work cables thru the strain relief bracket provided on the front of the base and connect to the terminals provid- ed. These connections should be checked periodical- ly and tightened if necessary.

joints, or to the metal framework of a building which has been effectively grounded. The U.S. National Electrical Code lists a number of alternate means of grounding electrical equipment. A machine grounding

stud marked with the symbol is provided on the front of the welder.

Listed in Table A.1 are copper cable sizes recom- mended for the rated current and duty cycle. Lengths stipulated are the distance from the welder to work and back to the welder again. Cable sizes are increased for greater lengths primarily for the purpose of mini- mizing cable voltage drop.

MACHINE GROUNDING

Because this portable engine driven welder creates its own power, it is not necessary to connect its frame to an earth ground, unless the machine is connected to premises wiring (home, shop, etc.).

To prevent dangerous electric shock, other equipment powered by this engine driven welder must:

a)be grounded to the frame of the welder using a grounded type plug,

or

b) be double insulated.

When this welder is mounted on a truck or trailer, its frame must be securely connected to the metal frame of the vehicle. When this engine driven welder is con- nected to premises wiring such as that in a home or shop, its frame must be connected to the system earth ground. See further connection instructions in the sec- tion entitled “Standby Power Connections” as well as the article on grounding in the latest U.S. National Electrical Code and the local code.

In general, if the machine is to be grounded, it should be connected with a #8 or larger copper wire to a solid earth ground such as a metal water pipe going into the ground for at least ten feet and having no insulated

AUXILIARY POWER RECEPTACLES

The auxiliary power capacity of the Commander 500 is 12,000 watts of 60 Hz, single phase power. The auxil- iary power capacity rating in watts is equivalent to volt- amperes at unity power factor. The maximum permis- sible current of the 240 VAC output is 50 A. The 240 VAC output can be split to provide two separate 120 VAC outputs with a maximum permissible current of 50 A per output to two separate 120 VAC branch circuits. The output voltage is within ± 10% at all loads up to rated capacity.

NOTE: The 120/240V receptacle has two 120V outlets of different phases and cannot be paralleled.

The Commander has two 20 Amp-120VAC (5-20R) duplex receptacles and one 50 Amp-120/240 VAC (14-50R) receptacle. The 120/240 VAC receptacle can be split for single phase 120 VAC operation. The aux- iliary power receptacles should only be used with three wire grounded type plugs or approved double insulat- ed tools with two wire plugs. The current rating of any plug used with the system must be at least equal to the current capacity of the associated receptacle.

STANDBY POWER CONNECTIONS

The Commander 500 is suitable for temporary, stand- by or emergency power using the engine manufactur- er’s recommended maintenance schedule.

The Commander 500 can be permanently installed as a standby power unit for 240 volt-3 wire, 50 amp ser- vice. Connections must be made by a licensed electri- cian who can determine how the 120/240 VAC power can be adapted to the particular installation and com- ply with all applicable electrical codes. The following information can be used as a guide by the electrician for most applications. Refer to the connection diagram shown in Figure A.2.

1.Install the double-pole, double-throw switch between the power company meter and the premis- es disconnect.

Switch rating must be the same or greater than the customer’s premises disconnect and service over cur- rent protection.
