http://www.markthewelder.co.uk/id25.htmlThe effects of polarity are not the same as what I have learned here. He also says never weave.Last edited by Taz; 01-25-2009 at 08:44 AM.
Reply:I'll let the others beat on him. Some is correct info, some is...I'll just let the others have their way with him...And then, after so much work...... you have it in your hand, and you look over to your side...... and the runner has run off. Leaving you holding the prize, wondering when the runner will return.
Reply:Ok first of all you want to use electrode neg for thin material not elec pos...  Elec pos gives deepest penetration  There is nothing wrong with weaving as long as the code allows it.   Low hydrogen rods are the ones that need to be kept in an oven.  All other rods just need to be kept Dry (but not oven dry).Get a good welding book to read !   Remember anyone can get online and put up a web site and be a professional.  There are a lot of people on here that don't know what they're talking about.   I find if I get 2 or 3 guys giving me the same answer on here its usually the right one...
Reply:I won't say much about about "markthewelder" except that you need to go to a source that knows what they are talking about. There are several sources of information available that will give you the TRUE facts about welding procedure. Mark is just another self proclaimed internet expert that has some things right and other things totally wrong.
Reply:"EXPERT STICK WELDING" says he. Modest Fellow isn't he. This was the first time I have ever been to that site. I did not know this expert existed. Much of what he wrote appears to have come from books (I am not saying he plaqurized those books) but much of it appears to be theory based.Many of you like me learned the stick 1st and at about 5 or 6 yrs old. I was at 6 now 58 thats 52 years of stick and I would never profess to be an expert, Like many here I am constantly learning and this is a great site for that. As far as mark the expert and his site its best to withhold judgement. Till I see some of his actual work.TomCo-Own CNC shop:Miller :1251 plasma cutter, MaxStar 700 TIG/Stick, & XMT 456 Multiprocess Welder.&  2 Hypertherm HPR260's Plasma CutterSorry I had a bad stroke but now I am back.

Reply:Originally Posted by Craig in DenverIt's why I enjoy the forums, if a guy puts up bad info, he'll probably get corrected by more than one person. It's still up to me to filter the good stuff. If I see something a few times, I'll start to believe it. You don't read each post as Law, you let dozens of them float around in your head until they fit together.
Reply:.........Sorry folks..........Today, one of my website visitors were kind enough to point out a list of technically incorrect items and various objectional words throughout my entire site, as well as this forum post.My 'eye has been off the ball' regards this website for a long while, I didn't notice that some idiot has been quietly changing page content on my site for quite a long time.I appreciate the problems that may have been caused for my website visitors for which I appologise and professional steps have been taken to improve site security.I would also like to say for the record that I do not, and never have, copied text from books or otherwise, to place on this or any other of my websites. My welding knowledge comes from a working lifetime of on-site and workshop welding and fabrication, studying welding principles, professional welder training, and from many worldwide sources including the TWI. Perhaps my website visitors that see my photographic work portfolio would realise that I do actually work as a professional welder. ........Thank you.Regards Mark.www.markthewelder.co.uk
Reply:You may work as a professional welder, but there's nothing "professional" about some of the BS put out by that site.Syncro 250 DX Dynasty 200 DXMM 251 w/30A SG XMT 304 w/714 Feeder & Optima PulserHH187Dialarc 250 AC/DCHypertherm PM 1250Smith, Harris, Victor O/ASmith and Thermco Gas MixersAccess to a full fab shop with CNC Plasma, Water Jet, etc.
Reply:As far as the "never weave " part you have obviously never ever been a pipewelder in the field.  Fab shop?  Maybe. Field?  No. My last qc would've got your money quick. Just sayin'...The bull$#%+ stops when the hood drops!
Reply:I believe the expression "bad" is invalid.The expression "We need this done, and we need it done before we can run again!" is valid.  It's one thing to have all of the time in the world, but when you have only two days in which to work, to get everything up to a running condition, you do what you can.  A lot of the time you'll be in a position where it doesn't need to be 100% welded out, but it does need to be back together in time for the place you are working at to run come Monday, only to go back to finish the job the following weekend.  A lot of the time, the welding is the fastest part of the process (in the sawmills and pulpmills anyway) yet the rest of the time is spent stripping/cutting/grinding/fitting/millwrighting and once that is finished, final weld out.  Of course, all of this can only start after one drags everything that you need to the location you are working in, and it is never convenient.  It's usually in some hole that shouldn't exist, but does and if there is a welding machine within 300' of where you are working, let alone a torch, consider yourself lucky! Yes, you have a welding truck, but it doesn't matter if you can't get the cable to the job!  And don't forget about that water hose in that oil covered sawdust hole you are working in, because you know that the first spark will set off a chain reaction and what you are working on will go up faster than you can snap a finger, so you'd better water down first!  Last edited by mb_welder; 04-19-2011 at 08:55 PM.
Reply:The location of the advice is important.  In Great Britain Rutile electrodes dominate.  Certainly the comments he makes about polarity apply to E 6012 and E 6013.  These rods will tolerate both polarities and AC.
