3 Secrets Your Welds are Trying to Tell You…

examples of welds with to high or low amperage, high or low wire feed speed, or fast or slow travel speed

Problem #1: Your Travel Speed

There is a proper speed your torch needs to be traveling. This speed increases as the material thickness decreases.

  • If you travel TOO FAST you will notice sporadic arcing sounds.
  • If you travel TOO SLOW you will notice a loud humming sound.
  • If you travel at the CORRECT speed, you will notice a crackling (“frying egg”) sound.

Problem #2: Incorrect Voltage Setting

The voltage is the main “heat” setting that get’s changed depending on the joint, metal thickness, gas type, and position of the weld. Always follow the manufacturer’s recommendations, not only for the machine but also for the welding wire being used.

  • If your voltage setting is TOO HIGH you will notice the sound of a whirling fan, you will not hear any crackling.  The welds will also look flat and wide.
  • If your voltage setting is TOO LOW you will notice a very snappy sound, like stepping on bubble wrap.  The welds will look ropey (or rope like) and high.
  • When the voltage setting is CORRECT you will hear the sound like “frying bacon”.  Welds will appear smooth and even.

Problem #3: Incorrect Wire Feed Settings

The wire feed speed regulates how much or how fast the wire is fed into the weld joint. Again, always follow the manufacturer’s recommendations, not only for the machine but also for the welding wire being used.

  • If the wire feed setting is TOO FAST you will notice rapid sharp snapping sounds.
  • If the wire feed setting is TOO LOW you will notice a high pitch humming sound.
  • If the wire feed setting is CORRECT you will notice a smooth low pitch crackling.
