AC TIG Puddle Won't Form

[M_Robertson]

I have inconsistent results establishing a puddle for AC TIG on aluminum using a Syncrowave 250. I have tried the following to remedy the problem:
* New tungsten
* Torch angle and rotating tungsten to redirect arc
* Different sized cups
* Adjusting HF dial
* Cranking up...

I have a MM211MVP that came with a spoolmate spool gun. There are settings for 4043 wire on the chart in the door but I have never found them (on the door, searching online...) for 5356 wire.

Does anyone know where to find them? Even a chart from another welder that shows both 4043 and...

I'm looking to do a few outdoor projects and I'd like them to look good and be maintanance free for years! I'd really like to have a bare metal finish and not have to deal with clear coating or powder coating, however, as I read more and more into different materials, I'm not sure this is a realistic...

Hello All. Im fabricating another batch of planter boxes in 1/4" 5050, but I'm having major cracking issues this time around. Though the one I've attached a picture of is a funny shape, most are rectangles....

I want to weld 7075 aluminum but not able to find recommended filler metal for it. Can any one give some idea about aluminum welding?...

Hello millerwelds forums! I'm hoping someone out there can help me get AC frequency up and running on my syncrowave 210. (My machine doesn't have the spoolmate capability in the bottom left corner, so it's not the latest model)

Here's the scoop:

-I hadn't had AC frequency adjustment...

I have a millermatic 200 with the spoolmatic 1. Everything works fine except the gas wont flow when you pull the trigger. Any ideas?

Ive been doing a lot of aluminum tig work lately with a Syncrowave SD 180 which i had thought was (and according to specs is) a bit under powered for 3/16" and 1/4" plate. Ive recently got a helium argon mix to get a bit more heat at the weld which is working really well. I no longer need...

I have recently learned that using green tungsten in an inverter machine is a no-no. I have been welding for over 15 years and I have never heard this until now when I purchased a Dynasty 700 machine. I have used the purple for a while and I am not very fond of it so far. I started using the green again...

I own a Miller Econotig, and I'm trying to weld 1/8 aluminum square tubing.
I believe all my settings are correct. 3/32 tungsten, 75/25 on my gas, pure tungsten (green), material is clean, A/C, ball on end of tungsten, and grounded directly to material.
I got machine, used, approximately...

Hey guys... i have a project were i need to fillet weld a 4" X 18' X .5" to another piece with the same dimensions. So when its done it looks like a "T". Im using a aluma pro with 1/16th wire (5356). Do i need to preheat this piece for an optimal weld? This piece is going to be a...

I'm sure this has been discussed before, but it can be like finding a needle in a haystack searching for some things.....so, sorry if this is redundant.

First of all, we're new to aluminum welding. We have a big project welding aluminum parts and are having problems with the wire melting...

Hi
Passport Plus 1/4 inch aluminum bar.
New to welding, with specific needs.
I want to weld 1/4 inch bar armatures to put canvas on.
So there is not much stress or weight - hopefully.

As to weight, would like to keep it down and would like to weld 3/16, 1/4 inch...

I am a self taught welder. I have tig welded for over 10 years, mainly steel stainless and silicon bronze. I would consider myself a very good welder. I have recently started working a lot with aluminum and am getting frustrated with what I feel are non satisfactory welds (mainly the presents of...
