been turned off. This can occur if the ambient
temperature is above 40°C or the duty cycle of the
machine has been exceeded. Leave the machine
on to allow the internal components to cool, when
the lamp turns off normal operation is possible.
Thermostatic fan: the fan is additionally
controlled by the thermal protection circuit.
This feature saves energy and also minimizes
the amount of dirt and other air borne particles
being drawn into the machine.
The fan is operating only while cooling is
needed.
3.
Power on/off Switch: Controls the input power to
the machine.
4.
Hot Start Control (LINC 405-SA only): Hot Start is a
temporary increase in the output current during the
start of stick (MMA) welding that helps ignite the arc
quickly and reliably. The potentiometer is used to
set the level of the increased current.
5.
Negative Quick Disconnect: Negative output
connector for the welding circuit.
6.
Digital Welding Current Meter with memory feature
(LINC 405-SA only): Shows present the value of
the welding current during welding; after welding it
continues to display the average welding current.
7.
Output Current Control: Potentiometer used to set
the output current (also during welding), from 15A to
400A.
8.
Local/Remote Switch: Remote Control Unit
K10095-1-15M and K870 can be used with this
machine. It changes control of the Output Current
from the machine Output Control (point 7) to the
K10095-1-15M or K870 and vice versa.
9.
Arc Force Control (LINC 405-SA only): It is a
function used during stick (MMA) welding in which
the output current is temporarily increased to clear
short circuit connections between the electrode and
the weld puddle that occur during normal welding.
10. Remote Control Connection: If a remote control is
used, it will be connected to the remote connector.
11. Positive Quick Disconnect: Positive output
connector for the welding circuit.
12. Fuse: This fuse protects the Fan Circuit.
13. Power Input Socket: Connect the supply plug to the
existing input cable, that is rated for the machine as
indicated in this manual, and conforms to all
applicable standards. This connection shall be
performed only by a qualified person.
14. Hole covered: For 48Vac socket K14027-1.
15. Hole covered: For circuit breaker which protects the
48Vac socket K14027-1.
Stick Welding (MMA)
For starting welding process with MMA method you
should:
Insert welding cable plugs into output sockets and
twist to lock them in place.
Connect the work cable to the welding piece with
the work clamp.
Fasten a correct coated electrode into the electrode
holder.
Connect the main plug to the outlet mains socket.
Set the Local/Remote Switch in required position:
local or remote.
Turn the Power on/off Switch on.
Set required welding current by knob of the Output
Current Control.
Obeying appropriate rules you can begin to weld.
Maintenance
For any maintenance or repair operations it is
recommended to contact the nearest technical service
center or Lincoln Electric.
performed by unauthorized service centers or personnel
will null and void the manufacturers warranty.
The frequency of the minatenance operations may vary
in accordance with the working environment where the
machine is placed.
Any noticeable damage should be reported immediately.
Routine maintenance (everyday)
Check cables and connections integrity. Replace, if
necessary.
Check condition and operation of the cooling fan.
Keep clean its airflow slots.
Periodic maintenance (every 200 working hours
but not more rarely than once a year)
Perform the routine maintenance and, in addition:
Keep clean the machine. Using a dry ( and low
pressure) airflow, remove the dust from the external
case and from inside of the cabinet.
Check and tighten all screws.
Mains supply network must be disconnected from the
machine before each maintenance and service. After
each repair, perform proper tests to ensure safety.
