Would adding a pulse controller to the machine help or should I skip spending $400?

On the 1/16” plate, it’s not really burning through on the bottom, but kind of caramelizing like stainless does without a back purge. Will have having a copper backing fix this issue?

Tried the 16ga again, cleaned it with a flapper disc. The welds turned out a little better and didn’t have the crap around it. Would switching to a gas lease help or should I hold off on that.

Getting any better, or should I just stick to eating paste?

3/16 plate running around 125 amps 1/16 filler.

I was practicing on 16ga due to that’s the material I will be welding the most. I was running 60 cause the slide calculator called that and 1/16 filler. I’ll bump it up and work on running faster.

Tweake, there’s the line between clean and dirty.

Thanks, it’s been about 3 years since I’ve held a torch. I feel it’s going to kick my ass for a while again. Thanks again. It is argon. It’s a bottle that I’ve had prolly 4 years or now. I didn’t clean the back side.

Cleaned the metal with a flapper disc before.

It does look crooked for some reason.

It’s a series 9 torch.

Stick out

The base metal hadn’t been galvanized before that I am aware of. It’s a sheet that I purchased from Lowe’s to dial in my welder and get comfortable with tig again before welding up an HK receiver.

DC- 1/16 70s-2. I wiped the metal down before welding.

Gas was set at 20cfh

16ga mild steel. 1/16 tungsten and 1/16 filler, #8 cup and 60 amp. What did I do wrong? Thanks

I have a syncrowave 250 at my dad’s shop. I may just bite the bullet and run 220 in my garage.

Looking to buy a 110 tig machine. Looking for something that has high frequency and ac. Looking at the miller dynasty 210dx or Lincoln square wave 200, but will consider other brands. Mainly will be welding 16ga steel and aluminum.
