MMA Welding Problems
Most problems with MMA welding are the result of not setting the correct welding parameters for the
welding rod being used. All welding rod packets have information on them in symbolic format , giving
suitable current range, polarity and type of weld (normally called 'position').
If you are in doubt about what these symbols mean, ask your welding rod supplier to explain them.
Choose an initial current setting towards the middle of the quoted range and if necessary practice on a
piece of scrap the same thickness as the job to be welded.
If the problem still persists have the RT2500 checked by a trained Newarc service engineer.
