Here Is my first question can I use straight Argon for mild steel and Aluminum? Should I use a spool gun for Aluminum? Any help with this would be appreciated.
Reply:Anyone?

Reply:Originally Posted by BrettI have both Mig and Tiged mild steel with argon . I dare say its not ideal and there fore there may be some compromises in weld quality and \or strength that I'm not aware of . I guess its up to the requirements that will be expected of the joints but yes you can do it.
Reply:Pure argon GMAW for steel will be a VERY low-penetration, high-profile weld bead. You can MAYBE make some artwork stick together, but anything else would be a lawsuit waiting to happen.A spoolgun is not always a necessity, but would be the proper way to GMAW aluminum unless you like stopping every few minutes to fix the machine's feed system. There are tricks you can do to minimize the frequency of needing to fix it, but if you have any volume of production at all, you'll want a spoolgun. This is when you use pure argon, of course.
Reply:I use CO2 for mild steel with my SP175 plus. Others like the 75/25 argon/CO2 mix. Penetration if best with straight CO2 but the welds are cleaner with the mix. For aluminum, obviously a spool gun would be best. If only they didn't cost almost as much as the welder. Lincoln recommends an aluminum welding kit for your machine. It's their part number K663-2. It retails at $57 US. It has some tips, a special roller and a non-metallic cable liner that is smooth enough to permit good feeding of soft aluminum wire. As mentioned above, you would want pure argon for a shielding gas on aluminum.Good luck.
Reply:What I will be Welding would be 3" long at a time or less. Just to repair a small cracks (ATV skid plates only). None of which are critical weld. Will I get by with the Aluminum Welding kit Lincoln Sells and straight argon for gas? Also what settings would you start welding aluiminum 1/8 plate just for touch up stuff as stated above. Thanks for the helpLast edited by Weld35; 06-27-2006 at 01:01 PM.

Reply:I just called lincoln and he told me that the spool gun is the way to go, But the kit will work for for very short work only. Touch up stuff really. He did tell me to make sure you wire speed and heat is at least 3/4 to max and use straight argon. Think I should try it out?

Reply:i have the same welder do they make a spool gun for it.i couldnt find one.
Reply:Nope. Only for the 215 thats what he told me.
Reply:A further review of the 175 Manual shows that there's not a word in there about MIG on aluminum. Maybe someone else can come and let us know how the 175 does on aluminum with just a change of roller and liner. I'm fairly certain that there are people on this website who do it regularly
Reply:I often weld aluminum (using pure Argon) with a Pro-Mig 175 and as long as I keep a few things in mind, it works fine.1. Keep the torch cable as straight as possible and plan you work to keep it that way. I've gotten into the habit of zip-tying a length of PVC conduit to the torch cable to help keep it straight.2. Run the power near max and adjust the travel speed to avoid burn through. You will also have to run your wire in the 7-9 range.3. Set your drive roller tension to as loose as possible to still have the wire feed properly. You should be able to block the wire exiting the tip and have the drive roller slip. Any tighter than that and you'll spend some time pulling out bird nests.4. Most of my aluminum welding is done with 4043 .035" wire (because I got 60# for free). It's solidifies more slowly and makes a more flexible weld, but the wire is so soft, it's like shoving cooked spaghetti up a garden hose. Once my current supply of wire is gone, I'm switching to 5356. It's a stiffer wire and will feed better. The down side to 5356 is that the wire itself will wear out the teflon cable liner sooner.Good luck.There are no small projects

Reply:Thats great to know. Thanks alot for the tips. I will give it a shot. Like I stated before it will just be for touch up work only. |
