Hi all,
I have just joined the forum after reading through many threads for the past year or so! I have been welding for about 3 years at home from some videos and a lot of practice. I started with MIG and then started to learn TIG.
I originally have had some bad gas problems before and have switched my gas bottle provider. The below is from the old company and one from the new company, same settings/gas flow everything, just swapped the bottles. Excuse the poor uniformity:
I come now seeking some more advice some time ahead of the above problem. I have just swapped 2 bottles of argon over (I normally do 2 at a time to save going back and forth). The setup was welding fine beforehand no problems and was getting results like this:
My uniformity has improved!
I have now connected up these bottles and am getting results like this (below). I switch between the two brand new bottles I have and no difference in results. Its almost as if the gas is making the welds turn that colour within the postflow. So I started to look at my setup.
Welding settings (bear in mind, since getting them setup for these brackets I haven't changed for atleast 6-8months):
Surely I can't just be having bad luck with gas? I feel as if my welder may have a problem but I don't have enough experience to comment properly.
Has anyone got any more advice? It would be greatly appreicate, its driving me mad!!
Thanks in advance.
EDIT: Apologies for the large images!

Welding settings (bear in mind, since getting them setup for these brackets I haven't changed for atleast 6-8months):
- Preflow: 1.0 seconds
- Welding Amps: 111amps
- Pulse time: 40%
- Pulse Amps: 28%
- Pulse Freq:155hz
- Post flow: 8.5 seconds
- Cup size 16 with 12-14 L.min flow
- I have swapped my gas lens and cup over with spares I keep - no difference
- Swapped out to a fresh tungsten - no difference
- Reduced and increased gas flow - no difference
- I have swapped to a spare old torch I have - no difference
- Completely stripped down the setup I currently use as I have a splitter for purging on other stuff I weld. Still no difference
- Checked for obvious leaks, regulator has very small bubbling from one of the fittings hence the reason for ordering (see below)
