ORBIMAT CA
| Operating instructions
Information on possible electrical fault sources: see Sec. 9.3, Page 64: "List of error messages"
Possible causes
•
Poor electrode quality, worn or scaled electrode.
•
Poor ground contact (open head to ground terminal).
•
Worn weld current plug, poor contact.
•
Rusty or soiled pipe surface.
•
No gas, wrong gas (never use carbon dioxide, even if it is mixed with argon!) or excessively short gas pre purge time.
•
Excessively large arc gap.
•
Humidity in weld head.
•
Excessively long hose assemblies (extensions).
Remedy
X
Eliminate possible causes.
X
Recommendation: Do not exceed a total hose assembly length of 15 m.
9.2.6
Machine does not start
If the operating voltage is active when the machine is started, the control computer starts the software.
Does nothing appear in the display after the machine is started?
Is the red "Stop" LED on the front of the machine lit up?
Possible causes and remedies
X
Check mains connection.
X
Ensure that main switch is lit up.
•
Dummy plug is missing from remote control connection.
•
EMERGENCY-STOP function of a (possibly) connected remote control is activated.
X

List of error messages
No.
Error message
Explanation/Elimination
01
Warning
A "warning" appears in the "info area" of the display (directly below the mains voltage
information during the process). The message can be combined with the parameters
of voltage, current or speed and the "high" or "low" specification. The message shows
that the limit value specified in the monitoring limits for the alarm were overshot or
undershot for the corresponding parameter.
Example:
"Warning: Low speed": The limit value of the weld speed specified for the alarm was
reached during the "low-current time".
This can be overshooting or undershooting. If one of the abort values is also reached,
the process is aborted and another message is output.
02
Gas problem
The process was aborted due to a problem with the gas.
X
Check hoses, bottle and pressure reducer.
X
Check sensor even if the gas is flowing in the sufficient quantity.
The message also appears outside the welding process if the gas was switched on
using the gas/water button and no gas is flowing.
03
Cooling water problem The process was aborted due to a problem with the cooling water.
X
Check hoses, water level in tank and pump operation.
X
Check sensor even if the water is flowing in the sufficient quantity.
X
Check water flow: Disconnect water return from machine for testing).
This message also appears outside the welding process if the water was switched on
using the gas/water button and no water is flowing.
