Ignition problems

The ignition generator generates ignition pulses with a voltage of up to 8,000 V. These ignition pulses can be a consid-
erable source of disruption (especially for computer-based control). The ignition pulses are introduced to the electrode
with high-voltage insulation via the hose package. Upon ignition, a current flow of potentially several hundred amperes
can arise in the weld circuit and be correspondingly disruptive (magnetic fields around the conductor and other high-
frequency fields). The machine controller is shielded from these disruptive fields. If problems are occurring with the arc
ignition, malfunctioning of the computer or a corresponding defect in the system cannot be ruled out.
Information on possible electrical fault sources: siehe Kap. 9.3, Seite 144: "List of error messages".
Possible causes
• Poor electrode quality, worn or scaled electrode
• Poor ground contact (open heads – 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 gas pre purge time too short.
• Arc gap too large.
• Humidity in the weld head.
• Hose package too long (extensions).
Remedy
X Eliminate possible causes.
X Recommendation: Do not exceed a total hose package length of 15 m.

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?
Possible causes and remedies
X Check the mains connection.
X Ensure that the main switch lights up.
• Dummy plug is missing from the remote control connection.
• EMERGENCY-STOP function of a (possibly) connected remote control is activated.
X Insert the dummy plug.
X Unlock the EMERGENCY-STOP button of the remote control.
