Reply:Maybe you should explain to us what BC EN 287 is. You are making the assumption that we know what standards and procedures the European Union has. Just for fun I am going to pick 4.
Reply:Sounds like answers on a written test question.   I'll go with number 4 as well.MM350P/Python/Q300MM175/Q300DialarcHFHTP MIG200PowCon300SMHypertherm380ThermalArc185Purox oaF350CrewCab4x4LoadNGo utilitybedBobcat250XMT304/Optima/SpoolmaticSuitcase12RC/Q300Suitcase8RC/Q400Passport/Q300Smith op
Reply:#4 is the  answer because of the preparation that goes into the weld. Used on 3/4" or greater metal and very difficult when joining multiple seams together. You see this done in pressure valves that must stand up to alot of constant stress.
