as for why anyone would still be using 5p vs. 5p+ my experience has been the lincoln 5p+ is more susceptible to moisture especially 5/32" and up. also more slag especially when running downhill. just my 2 cents

A certification is needed to see if you know how to weld. The only thing is, every welding job requires you to take a test no matter if you have a truck load of certifications.If you have ever worked in the chemical plants on shut downs or turn a rounds you could work for 4 or 5 different employers in a year and you half to take a test for each one.  Hope this helps.
