Work lead with ground clamp – 3m,
Gas hose – 2m,
Drive roll V0.8/1.0 for solid wire (assembly in the wire
feeder).
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 10° 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.

Input Supply Connection
WARNING
Only a qualified electrician can connect the welding
machine to the supply network. Installation 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
ground wires from the machine to the input source. The
welding machine
FILCORD i250,
FILCORD i300
, must be
connected to a correctly installed plug-in socket with an
earth pin.
Input voltage is three-phase 400VAC, 50/60Hz. For more
information about input supply refer to the technical
specification section of this manual and to the rating plate
of the machine.
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.
WARNING
The welding machine can be supplied from a power
generator of output power at least 30% larger than input
power of the welding machine.
WARNING
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!
Output Connections
