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.
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 welding machine is a percentage
participation of 10 minutes at which the welder can weld
at the rated value of the welding current, without
overheating and necessary break time of work.
Excessive extension of the duty cycle will cause
activity of the thermal protection circuit.
60% duty cycle:
Welding for 6 minutes.
The welder is protected against excessive overheating
from the transformer by he thermal protection.
Activation of the thermal protection is indicated by the
signaling lamp. After cooling down of winding to the safe
temperature the welder automatically switches on and
signaling lamp lights out.
Minutes
Input Supply Connection
Installation and mains outlet socket should 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. The allowable input
voltage is indicated in the technical specification section
of this manual and on the rating plate of the machine.
Verify the connection of grounding wires from the
machine to the input source.
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
been turned off. This will occur if the ambient
temperature is above 40°C or the duty cycle of the
machine has been exceeded. Leave the machine
on to allow the internal components to cool, when
the lamp turns off normal operation is possible.
The fan is controlled by the thermal protection
circuit. This feature saves energy and also
minimizes the amount of dirty and other air borne
particles being drawn into the machine.
3. Power on/off Switch: Controls the input power to
the machine.
