LCD Multi-Function Display (26)
When welding is not in progress the LCD Readout
displays the setting selected/being adjusted
using the Selection Knob (19).
During welding the LCD Readout
displays the actual welding current.
The parameter setting displayed is indicated by the LEDs beside the display:
SEC: Time (31)
%: Percentage (29)
Hz: Frequency (30)
AMPS: Current/Amperage (33)
If left inactive for several seconds, display will revert back to main welding current setting.
Also displays error codes if the protection system (27) is activated.

Error/Over Temperature Indicator Light
Error/Over Temperature Indicator Light (30) illuminates when duty cycle is exceeded and thermal
protection is activated. When thermal protection is activated, welding output will be disabled until
machines cools sufficiently and overload indicator lamp goes out.
This may also activate if there are electronic circuit failure issues.
When there is an error the LCD screen will display an error code to indicate what the error is. Refer
to the following table for error code explanations.
Code
Error
Solution
E01 –
E09
The machine has exceeded its safe
temperature or duty cycle.
Ensure the cooling fan is working. If not,
contact supplier.
Wait for machine to cool down.
E13
Input voltage has fallen below safe
tolerance level.
Check the voltage of your power supply.
E14
Input voltage has risen above safe
tolerance level.
Check the voltage of your power supply.
E15
Excessive current through IGBT
electronics due to machine misuse or
technical fault.
Ensure usage of machine is in line with
guidelines in this manual.
