Strong electrode burn-out • Pressure drop while cutting due to
Troubleshooting
Tab. 11
11 Dismounting
Cause
• Cutting rate too low
• Torch standoff distance too high
• Material thickness too high
• Output too low
• Cutting rate too low or too high
• Equipment parts worn or
damaged
• Output not adjusted
• Damaged or loose nozzle
• Contact with work-piece
• Start of cut at edge of work-piece
too fast
• Too much spatter when punching
holes
• Pilot arc struck too long and too
frequently in air
• Pilot arc too strong (depending on
power source)
incorrectly set pressure monitor
• Loose electrode
• Pilot arc struck too long and too
frequently in air
Dismounting may only be carried out by specialised personnel. Please make
sure that the shutdown procedures are strictly observed before the dismounting
is started. Make sure to include also the components integrated into the
welding system.
DANGER
Risk of injury due to unexpected start-up.
For the entire duration of maintenance, servicing, dismounting and repair
work, the following instructions must be adhered to:
• Switch off the entire welding system.
11 Dismounting
Solution
• Increase cutting rate
• Reduce torch standoff distance
• Use lower material thickness.
• Adjust output
• Adjust cutting rate
• Replace equipment parts
• Adjust output
• Tighten nozzle or protection cap
hand-tight, or replace nozzle, if
necessary
• Avoid contact
• Start cut at a lower rate
•
• Shorten/avoid ignitions in air if
possible
• Set pilot arc current to lowest
possible value
• Correct pressure monitor setting
• Tighten electrode by hand
• Shorten/avoid ignitions in air if
possible
