What causes BurnBack?

There are lot of reasons to cause burnback.
  • uncleaned contact tip.
  • Wrong tip diameter size
  • Uncleaned clogged liner prone to burnback 
  • overload or less load on the wire by drive rollers.
  • Not enough wire speed and feed causes burnback in MIG welding.
  • Too much voltage per wire speed.
  • wrong burnback settings
  • Bent MIG gun cable
  • Improper Distance between Job and welding torch.

How to prevent/avoid burnback?

burnback prevention remedies,how to avoid prevent burnback of welding tip,contact tube,welding knowledge,welding problems and remedies solutions,what causes burnback in mig welding

here are remedies to avoid burnback in GMAW welding.
  • clean tip as much time as possible.
  • Use tip diameter slightly bigger than the wire diameter. Generally, I use a 1.4mm diameter Tip for 1.2mm dia. wire.
  • mainly aluminium liners tend to clog so clean it after at least 15 meters weld.
  • Give right pressure by rollers on wire according to the material of feeler.less or more pressure on the wire will cause abnormal feeding in terms cause burnback while welding.so right drive roller tension is required.
  • Give more wire feed and speed.
  • use proper voltage don't use higher.
  • Use proper burnback control setting if you use max value it will come back to end of tip.
  • Use proper distance in between job and weld gun to avoid burnback in welding.

  1. I'm a professional welder for over 12 years. I have used different types of welding machines in my career. But the Millermatic 252 welding machine just amazed me. If you want to buy welding machines then I'll recommend you this welding machine.
