Why is the welding seam porous when using the Fimer TT205 DC Welding System?
- O
  owilliamsAug 4, 2025
  A porous welding seam can occur due to several reasons. Check that the distance between the electrode and the workpiece is approximately equal to the diameter of the electrode core. For basic electrodes, the rule is L=diam. X 0.5, and the inclination must not be excessive. Replace the electrodes, and ensure you keep them following the manufacturer’s/supplier’s instructions, as the presence of hydrogen due to humidity in the coatings of the electrodes, or erroneous conservation of electrodes can cause this issue. Also, maintain the correct distance between the electrode and the piece, because a welding arc that is too long can also cause this problem.

What to do if my Fimer Welding System displays [display:antisticking]?
- A
  Andre PetersAug 9, 2025
  If the Fimer Welding System displays 'antisticking', it means the electrode is in contact with the mass. To resolve this, remove the electrode from the workpiece.

Why am I getting a network error on my Fimer TT205 DC Welding System?
- B
  benjaminmurrayAug 13, 2025
  A network error with your Fimer Welding System can happen for a couple of reasons. First, a failure of one mains power supply phase. To fix this, check the connection to the power supply and check that the fuses are intact. Second, it could be due to mains overvoltage or undervoltage. Verify that the mains has a value in the range from 360Vrms to 440Vrms.

What to do if there is no fusion when using my Fimer TT205 DC?
- G
  Glenda BakerSep 12, 2025
  No fusion during welding with the Fimer Welding System can occur due to several factors. Ensure you are using the correct electrical parameters and reduce the welding speed if it's too high. Prepare the joint correctly by opening the angle of the caulker, and correct the welding position to ensure it is appropriate for the task.

How to troubleshoot failure to strike an arc on the Fimer TT205 DC Welding System?
- D
  Dr. Luke BenderAug 25, 2025
  If your Fimer Welding System fails to strike an arc, several issues could be the cause. First, check that both the pincer and earth clamps are correctly connected. Next, check the cables for any interruptions. Ensure there's good contact between the earth clamp and the workpiece, as well as between the pincer and the electrode. Verify that the welding parameter settings are correct. Finally, check the welder itself to ensure it is producing current.

Why does my Fimer Welding System switch off [display: off]?
- B
  Bradley MartinAug 28, 2025
  If the Fimer Welding System switches off and the display is off, it indicates a lack of tension on the supply grid. Refresh the power supply tension to resolve this issue.
