    Why does my Clarke weld MIG 90EN Welding System produce poor quality welds?
    • P
      perrytroyAug 14, 2025
      Poor quality welds with the Clarke Welding System can result from several factors. First, ensure sufficient gas is reaching the weld area and that drafts aren't blowing it away; increase the gas supply if needed. Second, verify you're using the correct gas and wire combination, consulting your MIG welding manual for the proper setup. Also, the workpiece should be clean and dry, free from rust, paint, dampness, oil, or grease. The wire should also be clean and dry. Finally, check the earth clamp and workpiece connection to ensure good contact.

    What to do if my Clarke weld MIG 90EN Welding System welder cuts out while in use?
    • S
      Stephanie AlexanderAug 18, 2025
      If your Clarke Welding System cuts out during use, it's likely that the duty cycle has been exceeded, activating the auto cut-out. To resolve this, allow the welder to cool for 15-30 minutes before resuming operation. Be aware that repeatedly exceeding the duty cycle can damage the welder, and it might indicate that the welder's output is too small for the application.

    Why is the wire feed erratic on my Clarke Welding System?
    • L
      Leah DanielAug 21, 2025
      Erratic wire feed in your Clarke Welding System can stem from several causes. First, slightly loosen the drum brake if it's too tight. Second, inspect the feed roller for wear and replace it if necessary. Third, increase the pressure on the feed roller, but avoid over-tightening. Fourth, ensure the wire is clean and free from dirt, rust, dampness, or bends; re-cut the wire to ensure cleanliness. Lastly, clean the liner with compressed air if it's partially blocked.

    What to do if the wire welds itself to the tip on my Clarke Welding System?
    • M
      mowenAug 25, 2025
      If the wire welds itself to the tip of your Clarke Welding System, it's likely due to one of two reasons. First, the wire feed speed might be too low. To fix this, unscrew the tip, cut the wire, fit a new tip, and increase the wire speed before operating again. Second, you might be using the wrong size tip. Ensure you fit the correct size tip for your wire.

    Why does the wire feed into a ‘birds nest’ tangle in my Clarke weld MIG 90EN Welding System?
    • S
      Scott HernandezAug 27, 2025
      If the wire feeds into a 'birds nest' tangle with your Clarke Welding System, it could be due to a couple of reasons. First, the wire might be welded to the tip. Address this as described above, and also reduce the feed roller pressure so that if a blockage occurs, the wire slips on the roller, preventing further feed. Second, the wire liner may be damaged, preventing smooth operation. If so, renew the wire liner.

    What to do if the feed motor operates but wire will not feed on my Clarke weld MIG 90EN?
    • A
      Andrew MossAug 31, 2025
      If the feed motor operates but the wire won't feed in your Clarke Welding System, check the following: Increase roller pressure. Re-cut wire square with no burr. Clean with compressed air or replace liner. Use only good “clean” wire and replace roller.

    Why are there loose coils of wire tangling around the wire drum inside my Clarke Welding System?
    • T
      Thomas RoweSep 3, 2025
      If loose coils of wire tangle around the wire drum inside your Clarke Welding System, the drum brake is likely too slack. Tighten the drum brake, but be careful not to over-tighten it.

    Why does the wire jam in the tip when welding aluminum with my Clarke weld MIG 90EN?
    • J
      johnsonemilySep 6, 2025
      If the wire jams in the tip when welding aluminum with your Clarke Welding System, the tip might be too small. Use a slightly oversized tip; for example, use a 1mm tip for 0.8mm wire. Note that this applies to aluminum only.
