Intoduction; Installation And Operator Instructions - Lincoln Electric SAF-FRO DIGISTEEL 355S Operator's Manual

Intoduction

DIGISTEEL 355S, 425S, 505S inverter sources have to
be connected with wire feeders WF 52D and WF 56D.
Signal from the power source will be displayed on wire
feeders user interface. For communication, inverter
source-wire feeder is used CAN protocol.
Inverter source-wire feed configuration allows the welding:

GMAW (MIG/MAG);

FCAW;

SMAW (MMA).
DIGISTEEL 355S, 425S, 505S work with the water cooler
®
COOL ARC 26.

Installation and Operator Instructions

Read this entire section before installation or operation of
the machine.
Location and Environment
This machine can be operate in harsh environment.

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
higher 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.
English
Break for 4 minutes.
The complete packaging includes the following items:

Inverter source;

USB with Operator's Manual;

Work lead - 3m;

Slow-blow fuse – 2A (2 units);

Gas hose -2m;

Chain.
Recommended equipment, which can be bought by the
user, was mentioned in the chapter "Accessories
Suggested".
Excessive extension of the duty cycle will cause the
thermal protection circuit to activate.

Input Supply Connection
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, phases, and frequency supplied
to this machine before turning it on. Verify the connection
of grounding wires from the machine to the input power
source. DIGISTEEL 355S, 425S, 505S can only be
connected to a mating grounded receptacle.
Input voltages is 3x400V 50/60Hz. For more information
about input supply please 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 type of protection 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.
See "Technical Specifications" chapter.
In case of powering welder from a generator make sure to
turn off welding machine first, before generator is shut
down, in order to prevent damage to welding machine!
