Advantages:
•
Wider operating range, ability to weld thinner
materials.
•
Less demanding in terms of wire placement, travel
speed and parameter adjustment.
•
High travel speed without lack of fill imperfections.
•
Good bead wetting, less undercut, flatter weld bead.
•
Good penetration profile. Less short circuit
disturbances. The High-Energy pulse cleans the
base metal and improves arc stability.
•
Pulse-on-Pulse provides "stacked dime" weld bead
appearance making the weld more uniform in
appearance.
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 maintenance operations may vary
in accordance with the working environment. Any
noticeable damage should be reported immediately.
•
Check cables and connections integrity. Replace, if
necessary.
Display Code
Code
Scrolling dash
Appears at power up while the machine is going through its self
configuration.
"Err" "####"
Fault code display. The first fault to occur will be displayed for three
seconds. The display will cycle through fault codes for all faults that
persist after the initial three-second period are displayed for 1 second
each.
"----" "----"
Weld mode is changing.
"####" "####"
Machine output is on. Left display is current, right display is voltage.
(on steady)
If actively welding, the displays are arc current and arc voltage. If not
actively welding, the display will show workpoint.
"####" "####"
Weld just finished – the average arc voltage and current will be
(blinking)
blinked for 5 seconds following a weld. If the workpoint changes
during this 5 second period, the display will revert to the above mode.
"no" "H2O"
No Water. The water flow sensor has detected a water flow shut
down (<0.7 l/min).
39
Glitch on the primary over current fault interrupt; possibly caused by
noise or a signal level.
(misc. hardware fault #1).
44
Main CPU problem. The DSP has detected a problem with the CPU. Check the machine ground.
47
Glitch on the CAP/heart beat interrupt; possibly caused by noise or a
signal level right at the trip threshold.
(misc. hardware fault #2).
81
Motor overload-average motor current exceeded 8.00 amps for more
than 0.50 seconds.
82
Motor overcurrent-average motor current exceeded 3.50 amps for
more than 10.0 seconds.
WARNING
Maintenance or repairs
Description
•
Keep clean the machine. Use a soft dry cloth to
clean the external case, especially the airflow inlet /
outlet louvers.
Do not open this machine and do not introduce anything
into its openings. Power supply must be disconnected
from the machine before each maintenance and service.
After each repair, perform proper tests to ensure safety.
A-7
WARNING
Corrective action
Check that Water/air cooled
torch selection switch. Set
this switch according to the
torch model (air cooled or
water cooled) being used.
Check the water cooler.
Check the water circuit.
Check the machine ground. If
problem persists contact an
authorized Lincoln Field
Service Shop.
If problem persists contact an
authorized Shop.
Verify motor armature is not
binding. Verify Wire Spool is
not binding.
Verify wire can move freely in
cable. Verify Spool Brake is
not set to tight
