damage which may have occurred in transit. After removing the components from the shipping
container(s), check the container for any loose parts. Remove all packing materials. Visually
check air passages of power source for any packing materials that may obstruct airflow through
the welder. Styrofoam or shredded materials should not be used to package the machine.
If the equipment is not being installed immediately, store it in a clean, dry, well-ventilated area
until installation.
3.2 Selecting a Location
The location of the power source should be carefully selected to ensure satisfactory and
dependable service. Choose a location relatively close to a properly fused source of electrical
power.
It is important that the machine be located in an open area where air can circulate freely through
the front and rear openings. If space is at a premium, leave at least 1 foot (300 mm) of clearance
between the rear of the power source and wall or other obstruction.
3.3 Selecting Suitable Supply Cables
The standard power input cable for the Workhorse 300MS welder is a high quality #14 gauge
that is 12.5 feet long. The secondary cables for arc welding vary in length according to needs,
but are normally 1/0 diameter and 25 feet in length. Heavier 2/0 gauge cables can be used to
extend the distance between the machine and work surface. Standard ground cables are 1/0 in
diameter and 25 feet in length. Work cables, automatic wire feeders and gas related acces-
sories are not supplied with the Workhorse 300MS power source and must be furnished by the
customer.

ONNECTING INPUT POWER
The primary cable supplied with the power source has 4 conductors. When connecting
an attachment plug or hard wiring to an electrical service box, connect the green/yellow
wire on a CE machine or the green wire on a non-CE machine to the ground. The
remaining 3 conductors can be connected to the phases in any order.
The brown conductor is not connected when input power is 240 V single phase.
Once connected to the primary power, the power source must be turned OFF before the
unit is moved.
