I would if each picture would choose something that you know the aluminum. To do this, the AC must be able to host. This heat load on the electrode and the aluminum oxide is necessary because of breaking. A truly professional machine can be controlled by the two parties in the run-time period, according to the aluminum oxide instead of merge for broken or there is a greater need. and can pulse arc welding, which is mainly made of stainless materials must be due to the lower heat input. Machine is not in my experience, but I suspect this is not the 300E's category. The Fronius is what, but you know the price. It has recently been discussed in the corn machines and they have a combined machine is:

The HF high-frequency ignition, in an arc without contact can arouse. It is beneficial because it reduces the chances of the weld electrode. The other half of the ARC-inch LIFT ignition. It affects the electrode to the workpiece and then turn the power of the gun. In theory, this is only a small voltage is generated and when you remove the gun from the mdb is created in the arc, but often sticks to the mdb, it does not immediately light curve (I used it boszankodni).

Do you have to be an adjustment to the gas előáramoltatás respectively. utóáramoltatás time of the gas can, within 5-30s. This protection of the weld is required. Ill. control the down slope time. This is the end of the suture is to prevent the formation of végkráter.

Clean

One thing is certain, flex aluminum will never go to him. But tisztitófolyakdékot be considered. The other is to see how much pressure there is a gas. The tungsten hegyezném not up to Alun must be blunt. The flex lubricates aluminum and pollution also drawn into the aluba the disk material.

First, I'll try an aluminum plate, if this phenomenon (which so far) will be something for your machine. Fund of the gas protection fault really. I think working on AC power?

If the end plate of the phenomenon of casting the culprit. I'll try előmelegítéssel 150-200C ° al. If nothing helps, sanszos, prepared to die casting aluöntvényt caught, which is full of saturated hydrogen. As a result of the secession of this kind can not be welded aluminum alloy.
