Butt Welding Aluminum Pipes

[drifterific]

I did some mild steel today and there is a slight difference in the sound between aluminum and steels. My torch is in the DC Negative hole. I am going to try a completely different piece of tungsten since ive been using the same one for aluminum and steels with grinding in between.

You should hear a big difference in sound between DC on steel vs AC on aluminum, especially with the AC freq. turned up that high as your photo shows. On DC the arc should be fairly quite, but on AC at that freq. you should be hearing a very high pitched buzzing sound. Also your post flow time looks a little low, although it may be the camera angle.

Yeah I just tried some aluminum an there is an increase of sound but not by much. I will search for the thread with the similar problem by wrenchtamer.


So I went back and listened to the videos that Jody posted on welding tips and tricks for the aluminum settings in part 5 and my welder in AC does not sound anything like the video. It kind of sounds like a louder hissing sound is the best way to explain it.

Contact me or Mike and we will be glad to help you. Likely it is a loose plug on the top board.

ok That sounds good. I will try to call sometime this week. I will also open up the welder and get some pics to post up here so everyone can see the internals of the welders.



So I got bored and decided to open up the welder and get some pictures. Maybe these will help someone in the future.

Wondering if you could take a picture of the back of the quick connect for the gas line on the front of the machine. If not, could you tell me what kind of hose is connected to it, and how its connected? (Rubber hose, plastic, hose clamp. crimped...ect.) Thats if you can even get to it to see it. Wow, what a wiring nightmare inside there.
Thanks

On the AC freq knob, moving it from 10 o'clock to 2 o'clock should change the arc sound a lot.

I can see in the pictures, a bend in the top rail. Looks like it was dropped and hopefully just popped the AC switch plug off like Wrenchtamer.

Call into support and we will check it out. Leave the cover off and the machine off for 2 hours before calling.

Here are some pictures of the gas fitting on the case. To me it looks like the black rubber hose is held on with a metal crimp to keep the line from blowing off. Hope these pics work for you. If not let me know and I can try to get different ones.
