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. SPEEDTEC 405S, 405SP, 505S and
505SP can only be connected to a mating grounded
receptacle.
Input voltages is 3x400V 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 type of protection 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.
See "Technical Specifications" chapter.
WARNING
When powering welder from a generator be sure to turn
off welding machine first, before generator is shut down,
in order to prevent damage to welding machine!

Controls and Operational Features
1. Power Switch ON/OFF (I/O): Controls the input
power. Be sure the power source is properly
connected to the mains supply before turning power
on ("I").
2. Status Light: A two color light that
indicates system errors. Normal
operation is steady green light. Error
conditions are indicated, per Table 1.
NOTE: The status light will flash green, and sometimes
red and green, for up to one minute when the machine is
first turned on. When the power source is powered it can
take as long as 60 seconds for the machine to be ready
to weld. This is a normal situation as the machine goes
through initialization.

3. Thermal Overload Indicator: It indicates
that the machine is overloaded or that
the cooling is not sufficient.
4. Replaceable Panel: User Interface can be installed,
in place of the replaceable panel, which allows to
adjust the welding parameters from the power
source. Panel with User Interface Kit can be
purchased separately (see "Accessories" chapter).
5. Negative Output Socket for the Welding
Circuit: Depending on the configuration
of power source, for connecting a work
lead, the electrode holder with lead or the
source/wire feeder welding cable.
6. Positive Output Socket for the Welding
Circuit: Depending on the configuration
of power source, for connecting a work
lead, the electrode holder with lead or the
source/wire feeder welding cable..
7. Control Receptacle: 5 pins receptacle for
wire feeder or remote controller
connection. To communication wire
feeder or remote controller with power
source is used ArcLink
