Should you experience a malfunction from your machine,
please consult the troubleshooting sections below first,
and complete some basic checks.
If the machine malfunction cannot be corrected with
these measures, contact your Kemppi maintenance
service workshop.
The problems listed and the possible causes are not
definitive but serve to suggest some standard and typical
situations that may present during normal environmental
use when using the A5 MIG Orbital System 1500.
Below instructions only apply to possible problems with
the carriage. Always ensure that the related welding
system is functional and ready for welding.
Problem: Check the following:
Carriage won’t work • Check that power reaches carriage (display is ON).
• Check that the welding power source is switched ON.
• Check the gun control connection and possible
Supersnake and separate control cable connections
• Check that control panels are switched on.
Dirty, poor quality weld • Check shielding gas supply.
• Check and set gas flow rate.
• Check gas type for application.

starts or stops strangely
Check that remote control buttons have been pressed
correctly:
• Stop+Up/Down ignites the arc and starts the carriage.
• If carriage is moving fast but arc is off, you may have
pressed Start button for too long.
Carriage moves unevenly • Carriage is not correctly mounted on the guide ring.
Check carriage position.

angle and adjust if necessary.
Torch height varies along the
pipe

necessary.
