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:
• Be grounded to the frame of the welder using a grounded
type plug or be double insulated.
• Do not ground the machine to a pipe that carries explo-
sive 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 vehi-
cle. 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 connected to premises wiring
such as that in a home or shop, its frame must be connected
to the system earth ground. See further connection instruc-
tions in the section 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 con-
nected 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 alternate means of
grounding electrical equipment. A machine grounding stud

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.

WELDING OUTPUT CABLES

With the engine off connect the electrode and work cables to the
output studs. The welding process dictates the polarity of the
electrode cable. These connections should be checked periodi-
cally and tightened with a 3/4" wrench.
Table A.1 lists recommended cable sizes and lengths for rated

is provided on the front of the
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.

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 out-
put 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.
• Loose connections will cause the output terminals to over-
heat. The terminals may eventually melt.
• Do not cross the welding cables at the output terminal
connection. Keep the cables isolated and separate from
one another.

AUXILIARY POWER RECEPTACLES
Start the engine and set the "IDLER" control switch to the "High
Idle" mode. Voltage is now correct at the receptacles for auxiliary
power. This must be done before a tripped GFCI can be reset
properly. See the MAINTENANCE section for more detailed infor-
mation on testing and resetting the GFCI.
The auxiliary power of the VANTAGE 400 consists of two 20
Amp-120 VAC (5-20R) duplex receptacles with GFCI protection,
one 50 Amp 120/240 VAC (14-50R) receptacle and one 50 Amp
240VAC Three-Phase (15-50R) receptacle.
The auxiliary power capacity is 12,000 watts Peak, 11,000 Watts
Continuous of 60 Hz, single phase power. The auxiliary power
capacity rating in watts is equivalent to volt-amperes at unity
power factor. The max permissible current of the 240 VAC output
