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.
Excessive extension of the duty cycle will cause the
thermal protection circuit to activate.
English
Break for 4 minutes.

Input Supply Connection
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 DIGISTEEL 255C/
255C PRO, DIGISTEEL 325C/ 325C PRO
connected to a correctly installed plug-in socket with an
earth pin.
Input voltage is 400 Vac 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 and cable sizes are indicated in the technical
specification section of this manual.
The welding machine can be supplied from a power
generator of output power at least 30% larger than input
power of the welding machine.
When powering the machine from a generator be sure to
turn off welder first, before generator is shut down, in
order to prevent damage to welder!
