Posted: Mon Apr 13, 2009 8:13 am Post subject: MIG welding aluminum

Kolb welding guys C

 

  I recently had some heli-arc welding done on some aluminum for my MkIII turbocharger. (the intercooler and TBI "top-hat").  Although this method of welding aluminum is the best C it can get real expensive!!  (I found the more often I went to this guy C the more expensive he got.  (surprise C surprise!)

 

  I talked to my local welding shop C and they say I can get some aluminum MIG welding wire C and use straight Argon gas (not the 25%/75%  CO2/Argon mix I'm presently using for my small MIG welder)

  The alum. wire and pure Argon allows one to weld "light" alum. projects.......they say.

 

  Is there anyone out there that has experience with this combination C and can say whether or not it works very well?  I have a lot of small aluminum projects that I'd do if I could weld them myself.

 

  I have one of those 110V Lincoln wire feed welders C with the MIG conversion kit and 125 cu.ft. gas bottle.  This set up is perfect for the home welder guy or gal.  You can weld ALL kinds of things around the house.  Nice set up.  If I could switch steel wire to aluminum C that would be awesome!!

Mike I [think ] you can get a spool gun to go with you welder that uses flux core wire.and you do not have to use any gas. this may be bad info .But your welding suply store can tell you for sure.Frank Goodnight

Yes it works  fine, the best type of gun for aluminum is one that pulls instead of pushes. I  have that set up with a gun that pulls (spool on gun)

Mike,  

   

Theoretically you can use your mig for aluminum, but the big problem is the alum wire will jam in the welding cable very easily because the reel in your welder and needs to push the wire all the way through your welding cable, and … because the alum wire is not very stiff – it jams.  

You probably would need a spool gun which has a small roll of aluminum right on the welding gun.  Don’t know if they make a spool gun for your welder or not.

Mike:  I have one of those Lincoln welders, but use flux core wire to weld steel.  I used to weld aluminum with a "spool gun", where the roll of wire sits above your hand.  I was told that a lot of the MIG's with the "whip feed" will not push the wire, and it will bind.  See if you can get a roll to borrow (make sure you have the right tip in it) and see if yours will feed before you pick up the argon.  Also, use a stainless steel wire brush or wheel to clean the oxide off aluminum before welding.  You can weld heavy stuff, but one pass at a time.  If it works, practice on a lot of scrap.  You may also have to change the filter setting or lens number in the helmet.  Be careful- if the aluminum gets too hot on multiple passes, it may collapse.  It stays hot for quite a while, and the heat spreads  through the material.

  

                                        Good luck

Tom and Frank C

 

  Thanks for the replies.  Frank C I wasn't concerned so much as using fluxless wire C as I was wondering how good a weld a guy could make.  Since I have to have Argon gas C anyway C so for me to weld aluminum C I'd only have to change the wire roll.

  

   It looks like both of you are on the same page C though C referring to the spool/gun.

 I'll check this device out.

  

 Thanks C  Mike W

   Ah ha!!  Now I think I understand something a little better.  I haven't checked out the spool/gun idea yet C but now I understand why the conversion kit for my welder has a new

 cable.

  

   When I talked to the guy at Airgas C he said the "MIG welding aluminum kit" has:

 A)  small aluminum wire roll

 B)  new feed cable with smooth teflon lining

   He didn't exactly know why the new cable came with the kit.  He wasn't familiar with the "softer" aluminum wire that may scrunch up.  I asked him if I could just use my present unlined cable C and he said he didn't know why not.  (now C I realize why not)

  

   One thing he did say is that you HAVE to use straight Argon gas C no CO2/Argon mix C like I get away with for steel welding.

  

   I think I'll take your advice C Dennis C toward the softer alum. wire C and go for the complete kit.  I'll check and see if there is one of those spool/guns available.

  

 Thanks guys C

Mike,

  

     I probably have the same welder  (WP-125) and my plan was to do lite aluminum also. I bought the MIG  conversion, argon tank, aluminum wire, then found out that you also  have to have a new non metallic liner in the cable that feeds the wire  along with some other stuff, couldn't find the liner or "other stuff" so I have  never been able to try it.  The liner is needed to prevent the wire  from binding and also to prevent contamination of the wire.  I think the  wire feed wheel is the "other stuff".  Another way to go is to get a handle  that has the wire spool attached which eliminates the wire having to  go through the long cable.   

  

     Or you could buy your own AC/DC output  TIG welder for a little over $2000.00 ----  It must be AC output or  you cannot do aluminum.

  

 My wish list is too long.

  

 V/R,

 Dennis in MD.

Hi Dennis Watson C

  

   Your welder is the newer version of mine.  I have the 115V Lincoln "Weld Pak 100".  Here's what I know C up to this point;

   This is a dynomite welder for all the medium to small steel welding projects I do.  I bought the K610-1 conversion kit C which turns it into a genuine MIG welder C plus I had to buy a decent size gas tank.  I'm not sure it makes it all that much better.  Maybe a little.  Heck of a set up for around the shop!!

  

   I haven't found anyone who sells a spool/gun that fits my small welder.  However C I did find a product brochure that says to convert my Weld Pak 100 to weld aluminum C I need the additional K664-2 kit (along with the gas kit above K610-1).  This kit has the smooth lined cable C to keep it from scrunching up.

   A welding supply store sells the K664-2 kit on eBay for $65 C incl s/h.  (The first kit K610-1 cost me about $135 or so.  This kit contained the gauges C hose C and some misc parts to convert my welder to a MIG welder.)

   

   So C I guess I'll go ahead and buy the aluminum conversion kit C and see how it does.  

  

   BTW.  According to the Airgas guy C he said I don't need a darker lens for my helmet C like a TIG welder would need.

  

 Thanks to all for your help C

Mike , I belive that Miller makes a spool gun that works with linclon welder [ it,s quite a bit cheaper than the linclon spool gun. ]  My welder is the linclon 140c and the Miller gun works 

with it.

I have been a Welder for over 30 years a lot of the  guys have good info but here is my opinion of what I would do  

 First,  How thick of material are you looking to  weld, anything  1/8 inch and thicker, a spool gun works great I run a  couple L-Tec 28-A spool guns and Profax spool gun I like the L-TEC better,   but these are more for production  work. 

 if your looking to weld any thickness material "thick  or thin" a Tig Torch

 hooked to a welding machine with AC & High Freq is  best  no matter what Process you decide on 100% Argon gas is the only  one to use to weld Aluminum  

 keep  the welding area super clean durty aluminum  does not weld good at all,  Stainless steel  brush  (good  advice ) 

 I never had much Luck with the smaller mig machines  welding aluminum and I have tried a few different ones over the years  

 Good luck with your welding adventure and if I can be  of any help feel free to ask

Thanks for the tips C Ellery.  At his time C and within my budget C I think I'll have to try that kit made for my small MIG welder.  I'll post a comment about my successes or failures C after I get a chance to check it out.

  

 My aluminum welding is what most could call "light".  Probably 1/8" or less.  I'm just looking for something that can do small projects once in awhile C without spending money on a TIG welder.

Oh yes I am back to work on it still re working 3  other guys work on it  someone re designed some things on it that I  don't like the looks of and 

 im not really in a hurry  to get it  together  real fast unless the wind blows a bunch of cash my way out of the  money tree, so I plan on taking my time I plan on having this one for a long  time

   I have been a Welder for over 30 years a lot of the    guys have good info but here is my opinion of what I would do    

   First,  How thick of material are you looking    to weld, anything  1/8 inch and thicker, a spool gun works great I run a    couple L-Tec 28-A spool guns and Profax spool gun I like the L-TEC better,     but these are more for production  work. 

   if your looking to weld any thickness material    "thick or thin" a Tig Torch

   hooked to a welding machine with AC & High Freq    is best  no matter what Process you decide on 100% Argon gas is the    only one to use to weld Aluminum  

   keep  the welding area super clean durty    aluminum does not weld good at all,  Stainless steel  brush     (good advice ) 

   I never had much Luck with the smaller mig machines    welding aluminum and I have tried a few different ones over the years    

   Good luck with your welding adventure and if I can    be of any help feel free to ask
