ELECTRICAL CONNECTIONS

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 to which this engine driven welder supplies power must:

WARNING

• Be grounded to the frame of the welder using a

grounded type plug or be double insulated.

WELDING OUTPUT CABLES

With the engine off connect the electrode and work cables to the output studs. The welding process dic- tates the polarity of the electrode cable. These con- nections should be checked periodically and tightened with a 3/4" wrench.

Table A.1 lists recommended cable sizes and lengths for rated current and duty cycle. Length refers to the distance from the welder to the work and back to the welder. Cable diameters are increased for long cable lengths to reduce voltage drops.

• Do not ground the machine to a pipe that carries

explosive or combustible material.

When this welder is mounted on a truck or trailer, its frame must be electrically bonded to the metal frame of the vehicle. Use a #8 or larger copper wire connected between the machine grounding stud and the 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 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 joints, or to the metal framework of a building which has been effectively grounded.

The National Electrical Code lists a number of alter- nate means of grounding electrical equipment. A machine grounding stud marked with the symbol

is provided on the front of the welder.

WELDING TERMINALS

The VANTAGE® 400 is equipped with a toggle switch for selecting "hot" welding terminal when in the "WELD TERMINALS ON" position or "cold" welding terminal when in the "REMOTELY CONTROLLED" position.

CABLE INSTALLATION

Install the welding cables to your VANTAGE® 400 as follows.

1.The engine must be OFF to install welding cables.

2.Remove the flanged nuts from the output terminals

.

3.Connect the electrode holder and work cables to the weld output terminals. The terminals are identified on the case front.

4.Tighten the flanged nuts securely.

5.Be certain that the metal piece you are welding (the “work”) is properly connected to the work clamp and cable.

6.Check and tighten the connections periodically.

CAUTION

Loose connections will cause the output termi- nals to overheat. The terminals may eventually melt.

Do not cross the welding cables at the output ter- minal connection. Keep the cables isolated and separate from one another.
