For GMAW, FCAW-GS and FCAW-SS process, the
technical specification describes:
Type of welding wire
Wire diameter
Recommended equipment, which can be bought by
user, was mentioned in the chapter "Accessories".
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.
Example: 60% duty cycle
Welding for 6 minutes. Break for 4 minutes.
Excessive extension of the duty cycle will cause the
thermal protection circuit to activate.
The machine is protected from overheating by a
temperature sensor.
Minutes or decrease
Duty Cycle
When the machine is overheated the Thermal Overload
Indicator light will turn "ON" on the front panel and the
output of the machine will turn "OFF". When the machine
has cooled to a safe temperature the Thermal Indicator
Overload light will go out and the machine may resume
normal operation. Note: For safety reasons the machine
will not come out of thermal shutdown if the trigger on
the welding gun has not been released.
Input Supply Connection
WARNING
Only a qualified electrician can connect the welding
machine to the supply network. Installation the outlet
plug to power lead and connecting the welding machine
had to be made in accordance with the appropriate
National Electrical Code and local regulations.
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.
For machines having the following KNUMBER:
K14054-1, K14055-1, K14056-1, K14056-3: the
allowable input voltage is 3x400V 50/60Hz.
K14054-2, K14055-2, K14056-2, K14056-4: the
allowable input voltages are 3x230V 50/60Hz and
3x400V 50/60Hz (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 input voltage:
The input cable must be disconnected from the
mains supply and the machine switched OFF.
