  • I'm going to try to demonstrate some of the most common problems or mistakes that beginning

  • arc welders encounter. One is which the arc will not start, or the arc rod sticks. Neither

  • is cause for panic, and is usually the result of one or two things. Either your voltage

  • is set too low or the rod you're using for the job is too big. A third possibility is

  • that your material is dirty. That is it might be too rusty, painted or, in some other ways,

  • interfering with the electrical contact with the table. Here you can see we have no flow

  • of electricity whatsoever and, therefore, it's impossible to strike an arc. A less common

  • problem, but one you may encounter in any case is that your voltage is set too high

  • or that your rod is too small for the job that you've selected. As you can see here,

  • the rod fails to penetrate. Metal splatters everywhere, and otherwise prevents you from

  • making a good weld. A good rule of thumb is to check your manufacturer's guidelines to

  • see which rod is recommended for what thickness of metal and what range of amperage. Those

  • ranges, high and low, should never be exceeded.
