Installation and Operator Instructions

Read this entire section before installation or operation
of the machine.

Location and Environment

WARNING

Do not lift this machine using lift bail if it is equipped
with a heavy accessory such as trailer or gas
cylinder.

Lift only with equipment of adequate lifting capacity.

Be sure machine is stable when lifting.
The HOT ROD 500S welders can be stacked three high
when the following precautions are observed:

Be sure the bottom machine is on a firm, level
surface suitable for the total weight (610kg) of the
stacked machines.

Stack the machine with the fronts flush.

Be certain the pins on the top font corners of the
lower machines fit through the holes in the base
rails of the upper machines.
This machine will operate in harsh environments.
However, it is important that simple preventative
measures are followed to assure long life and reliable
operation:

Do not place or operate this machine on a surface
with an incline greater than 15° from horizontal.

Do not use this machine for pipe thawing.

This machine must be located where there is free
circulation of clean air without restrictions for air
movement to and from the air vents. Do not cover
the machine with paper, cloth or rags when
switched on.

Dirt and dust that can be drawn into the machine
should be kept to a minimum.

This machine has a protection rating of IP23. Keep
it dry when possible and do not place it on wet
ground or in puddles.

Locate the machine away from radio controlled
machinery. Normal operation may adversely affect
the operation of nearby radio controlled machinery,
which may result in injury or equipment damage.
Read the section on electromagnetic compatibility in
this manual.

Do not operate in areas with an ambient
temperature greater than 55°C.

Duty cycle and Overheating

The duty cycle of a welding machine is the percentage of
time in a 10 minute cycle at which the welder can
operate the machine at rated welding current.
Example: 60% duty cycle:
Welding for 6 minutes.
Excessive extension of the duty cycle will cause the
thermal protection circuit to activate.
English
Break for 4 minutes.
The welding machine is protected from overheating by a
thermostat. When the machine is overheated the output
of the machine will turn "OFF", and the Thermal Indicator
Light will turn "ON". When the machine has cooled to a
safe temperature the Thermal Indicator Light will go out
and the machine may resume normal operation.

Input Supply Connection
Installation and mains outlet socket shall be made and
protected according to appropriate rules.
Check the input voltage, phase, and frequency supplied
to this machine before turning it on. Verify the
connection of grounding wires from the machine to the
input source. The allowable input voltages are 3x380V
50/60Hz and 3x415V 50/60Hz (415V: factory default).
For more information about input supply refer to the
technical specification section of this manual and to the
rating plate of the machine.
If it is necessary to change the input voltage:

The input cable must be disconnected from the
mains supply and the machine switched OFF.

Remove the rear access panel cover from the
machine.

Reconnect X4 and X5 according to the diagram
below:

Replace the rear access panel cover.
Make sure that the amount of mains power available
from the input supply is adequate for normal operation of
the machine. The necessary delayed fuse (or circuit
breaker with "D" characteristic) and cable sizes are
indicated in the technical specification section of this
manual.
Refer to points [1], [13] and [14] of the images below.
When powering welder from a generator be sure to turn
off welder first, before generator is shut down, In order to
prevent damage to welder!
