Complete NEWB w/ Precision Tig 225

admin

I bought a lincoln Precision Tig 225 as my first welder.  I have a trailer project now.  I need to weld up some 3/16 angle iron on the trailer rails.  My buddy bought me Fleetweld 180 (6011) rods.  Can I run those on DC? If so DCEN or DCEP and amperage recommendations for 3/32 rod on 3/16 steel?  Thanks in advance. For what its worth I am very well aware I didnt buy the typical beginner welder.  Thats how I do things.  I hate buying stuff three times!!

Reply:Start around 60A on DCEP.
Reply:Ever see the windmill farms in Palm Springs CA?   Well thats the valley I live in so......  thats why no Tig.  DCEP huh? Not sure why but I was expecting people recommend DCEN.  60 Amps sounds about right.  maybe as high as 80?
Reply:More penetration with DCEP.  DCEN would be good for sheet metal thickness.
Reply:What is the amperage range I should be in .  I tried 60-70 on scrap today and it really had a big tendency to stick when trying to strike the arc.  Is 65 dcep on 3/32 6011 rods too low for 3/16ths 2" angle iron?  Its my first ever attempt at welding and should say it was quite nerve racking with all that buzzing, sparking etc.  I assume you get over that quickly.  Can you cahnge the electrode in the stinger with the machine on?  any precautions other than the obvious like not sitting on the workpiece while you do it.  Also how much of a 12" rod would I expect to use for a 2" long weld.  I was surprised to see that I burned through half the rod and there was hardly any weld on the scrap.  Looked like a god awful solder splatter.  LOL  I was trying to focus on the weld puddle but found it impossible.  Overwhelmed I guess?

Reply:I answered my own question.  Someone on here wrote "do then ask".  Couldnt agree more.  Just do it.  I quickly learned that 55 amps wasnt enough and 73 burned through my metal if you pause for just a second.  63 amps oh so nice.  I am very happy with my weld after the third attempt.  First ever try was absolute splattery mess.  I wasnt watching my arc length.  Second attempt burned through the steel. Third attempt got my side to side going and laid down a nice bead.  I can see the area I welded on the other side.  What should I be looking for to know the penetration was acceptable?  Any complete newby reading this, take my advice and just go do it!!  Very exciting when it comes together.  Striking an arc was miserable the first couple tries too but now I have the hang of it.  Very exciting stuff!!!   Got my argon cylinder filled up today.  Maybe I wil try my hand at tig tonight. Just kidding one step at a time LOL.
