Weldclass Weldforce 135S Problems and Solutions
The Weldclass Weldforce 135S is a popular welding machine, but it can experience some common problems. Here are some of the most common issues and solutions, as recommended by experts:
- Arc starts poorly. This is often caused by a dirty or corroded contact tip. To fix this, clean the contact tip with a wire brush and apply a light coat of anti-seize compound.
- Arc wanders. This can be caused by a number of factors, including incorrect welding parameters, a dirty workpiece, or a loose ground clamp. To fix this, adjust the welding parameters, clean the workpiece, and tighten the ground clamp.
- Welding beads are uneven. This can be caused by a number of factors, including incorrect welding technique, incorrect welding parameters, or a dirty workpiece. To fix this, practice your welding technique, adjust the welding parameters, and clean the workpiece.
- Welding beads are porous. This is often caused by moisture in the shielding gas. To fix this, use dry shielding gas and make sure that the gas lines are properly purged.
- Welding beads are brittle. This can be caused by using too high of a welding current or by using the wrong type of welding wire. To fix this, lower the welding current or use a different type of welding wire.
If you are experiencing any of these problems with your Weldclass Weldforce 135S, following these steps should help to resolve the issue. If you are still having problems, you may need to contact a qualified welding technician for assistance.
