Welding Aluminum Rod

Do not get a clean seam welded to the alu.
Spurts and Smokes very strong, flying around the many small pickle.
Approaches are quite small because of a weld, but something basic is still wrong.
Do not know further.
This is available:

-MIG/MAG Inert gas welding up to 180 amps
Hose nozzles package with Teflon liner and 1.2 mm aluminum
Aluminum welding wire 1.2 mm Ai mg4, 5
Argon 99.9%
jedemenge rest-pieces aluminum (not anodized practice) to.

Who can tell me what I can do better.

How many amps do you have set? Although I have is with the welding of aluminum is not very much experience, but according to his catalog of Eurotrode 1.2 wire for 120 - 240 amperes welding current. Depending on the thickness of the parts can there possibly be even close to a 180A unit.

The current scale of 1-7 goes!
Take 4-6 alu for thinner (2mm) and 7 for thick aluminum (3-4mm)!
One says you can only aluminum with 250 A welding equipment others say it is also small.
Now I do not know.

AC at MIG? I think that now you have confused with TIG.
Basically you can weld aluminum with small devices. I had a long time ago so'n 105A small device that I've even by 5 mm (! Welded) aluminum. But that was what masochist, even though I had succeeded in an acceptable outcome. Your settings seem to me realistic. Come for the feed with the alu wire right? Did you feed rolls for aluminum, both roles with a semicircular groove and match the wire diameter? If not enough wire is clean nachgefördert helps everything else nothing.

Related to the wire feeder of, now that you mention it, perhaps we are getting closer.
Would also provide a basis why I badly can pull a seam in one slip by.
I looked around me once in a heimwerker shop for welding and informed.
That makes absolute sense to roll with me has been recommended devices with multiple feed drive roll with 3 or even 4th
In momemt I nuire 1 roll.
Yesterday I 5mm thick aluminum welded to gleube hardly weld with a fairly good-looking.
But why is so good I do not know thinner aluminum funkioniert not again.

It is true that a 4-roll feeder for aluminum is preferable. The number of roles is in fact always even, so 2 or 4 Otherwise, we would indeed run for a role in free space. One can of course also with a 2-roll feed aluminum welding. However, the hose package should then be no longer than 3 meters. The sealer such a way that the package is as straight as possible when welding, is also not an error. Then, as I said the right roles and the right to Drahtduchmesser soul in the hose package.

What color is the soul in the hose package? Normal Teflon souls i.d.R. color coded. Blue to 1.0 mm, red for 1.0 and 1.2 mm, etc. A blue soul has, for example 1.5 mm internal diameter, which would wire it for 1.2 too narrow and too much friction there. Such equipment should also buy as much as possible in stores for Welding Products. In the home improvement stores, the prices of these items to wear are completely covered!

The fact that the thin aluminum does not work, could also be on the feed. As applied here also less feed, fall irregularities stronger. The finer work, the more accurate the parameters must be met.

I'd like (because my equipment does not have Tig AC) can try a bit of time and aluminum welding.

My device (Oerlikon Citoline 200T) can change the polarity, I need to do this? Can I connect Argon 4.6? How much liter / min /? Which wire gauge? 4mm sheets should be ....

Is there anything else to consider?
Mal Write your experiences!

The polarity under no circumstances change, usually located on the burner before always plus.
Argon 4.6? Selbstvernatürlich.
Wire diameter less than 1mm, more 1.2 mm.
Gas flow is determined by the diameter of wire: wire diameter be set * 10 = l / min
Kunstoffseele fit into the tube package.
Currents (at 4 mm) fillet weld at: 160-200Ampere in butt gap width with <= 2mm: 100-120Ampere

Remains to be mentioned, that should be the travels along a AlMgSi 05 alloy. Why? with which it is best to weld.

Regarding the amount of gas you lie with 8 to 10 L always correct. Do not forget the wire feed rollers attract too much. Just so that the wire to hold the role in the slips.

For someone who has welded aluminum never has it jaaaa welds are a lot different! to say no to schllecht.
If the machine is set correctly and all the bells and whistles, then it is no problem.
The speed is much higher as steel.

Wire of 1.2 mm is ok, and I'd take him from Esab or Elisenthal, we weld with them day after day without any major problems.
