Installation and Operator Instructions

Read this entire section before installation or operation
of the machine.
Location and Environment
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 40°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.
60% duty cycle:
Welding for 6 minutes.
Excessive extension of the work duty cycle will cause
the thermal protection circuit to activate.
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.
Minutes
Input Supply Connection
Installation and mains outlet socket shall be made and
protected according to appropriate rules.
Break for 4 minutes.
or decrease
duty cycle
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 3x230V
and 3x400V 50Hz (400V: 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 main supply voltage:
•
Ensure that the input cable must be disconnected
from the main supply and the machine switched
OFF.
•
Remove the top panel from the machine.
•
Reconnect X12 according to the diagram below.
•
Replace the top panel.
Make sure the amount of power available from the input
connection 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, 3, 12 and 13 of the images below.

Output Connections

Refer to points 5, 10 and 11 of the images below.
Controls and Operational Features
1. Power Indicator: After input power is connected and
the power switch is turned on, this lamp will light up
to indicate the machine is ready to weld.
2. Thermal Overload Indicator: This lamp will light up
when the machine is overheated and the output has
A-2
