Solution
• Increase the micro wire current and speed .
• Displace the torch slower and / or make circular or
zigzag movements with the nozzle.
• Diminish the micro wire current and speed.
• Displace the torch faster and / or use less circular
or zigzag movements with the nozzle.
• Correct the distance between the nozzle and the
work piece (from 0.31" to 0.39").
• Increase the micro wire current and speed.
• Correct the distance between the nozzle and the
work piece (from 0.31" to 0.39").
• Diminish the micro wire current and speed.
• Displace the torch faster. No dot make circular or
zigzag movements with the nozzle.
• Correct the distance between the nozzle and the
work piece (from 0.31" to 0.39").
