Not to nag, but... if you are tepid on running 180 amps on 1/8” material, you’ll go absolutely freak show on 1/4”. You’ll need every bit of the 220 amps your HTP can deliver to get that to wet out. For your current practice, 160-180 amps, 3/32 filler. You’ll find better balance between beads and we...

OK Great!!! If I get permission to post more photos I'll give it a try!

It's an S10+ Samsung. I tried touching the screen and it just put a slider bar up where I can adjust the backfill lighting. But I'm gonna do some I-net searching on manual focus for the S10+ and see what I can come up with. Ah, there's your problem...Android. Throw it away and go get an iPhone! :lo...

Doug, Definitely listen to cj, but when you take a pic focus before you snap it. Not sure what type of phone you have, but on the iPhone you can just touch the screen where you want it to focus and it will focus there. Some of your pics are hard to see if there is porosity or not. This last group i...

Doug, what i'd do is practice just running beads on the same flat stock thickness material that I plan on building with? After I get that down, practice adding filler (butt joint) to get right thru to the back side of material to set my muscle memory....then learn to slack off just a tad so I don't...

More heat, please. Look at the backside of your welds (butt joints especially). That low of amperage isn’t pushing through. Your beads are laying on top of the material, not penetrating. Don’t fear the heat. Crank it up, mash the pedal, stuff the filler in there. Stop regularly if you’re struggling...

Apparently I don't have the skill set to drive the foot pedal @ 180amps when the metal is cold then throttle it back as the metal heats up. I do think these 2 pieces of 2" x 2" square tubing are acting as tremendous heat sinks and are causing the cold start problems as this is the only co...

You seem like you've approached the problem in an intelligent manner. Sometimes when trouble shooting, the simplest problems are easy to overlook. Can you hear your gas flow start and stop each time? That would mostly tell you the valve is actuating? I missed if you answered about any problem on st...

I'm going to remove the torch gas lead from the welder and take the hose off the regulator looking for restrictions or loose/leaking connections. The flow indicator ball indicates gas is flowing ~13 SCFH. Cup is the standard #6 Alumina. Something is very strange. I'm not the most intelligent guy on ...

I started out with a gas lens set but still kept stick out short. Didn't take long to figure out how limiting it was. More stick out gives better visibility and just seems like there's more room. I was horrible at estimating and when I started measuring stick out things got easier. Good luck. Keep ...

I recreated the part, sort of, and yeap my memory failed me, lol. It wasn't 200Hz, it was 200A! It took that much amperage at that high of a frequency to get a puddle established. https://drive.google.com/uc?export=view&id=1tbjcyXwm1aZZ6FTnNChKIG-7CuZ3SuHK Sorry for misleading you Doug! I'll be...

Had one of those 'Ahhh Haaa' moments. At times, when I'm on a roll, I can weld 4 fillets welds that actually come out pretty good. First one starts good and the other three are even a bit better - most of the time. Then.... I set up to do the next one and the first weld, on cold metal, pukes.... I m...

Got'cha'!

Replicating Doug's set-up almost exactly. I need to see where my memory failed me! :oops: https://drive.google.com/uc?export=view&id=1tQs9e3mpLmUU5_JMVetPnFTis3UPrUL5 https://drive.google.com/uc?export=view&id=1tPOB307LKS5C38C_6W2LukE-YQ1o_SXD https://drive.google.com/uc?export=view&id=...

Yes, that is what I'm referring to. When you did these welds, the little green light for AC light was blinking? The one I mean specifically is the one right above the "AC mode" button, below where it says "AC on". Was that one blinking when you did these welds? I'm aware of whic...

I did the first day I got the welder and it didn't take me long to figure out I didn't know what I was doing so I reverted back to simple AC balance control. I'm assuming you're referring to the ability to independently set the DCEN and DCEP values[/color] Yes, that is what I'm referring to. When y...

Looks much better. Bump the amps to 200 and weld. Learn to use the pedal to manage your puddle. Thanks... These welds were done @ 170A and 90F 65B 12CFH. 200 amps sounds good. I tried doing these same welds @160A and starting was a bit problematic and I was pretty much full pedal all the time.. The...

OK.... final report. Well I may come back and post some pictures... I appears that cj737 hit the nail on the head. As I started dialing back the frequency from 200Hz to 100Hz pooling the initial fillet got easier and easier. And the welds started looking a bit better as well. So last weld was 180amp...

With a #6 cup, you don’t need 25CFH. You’re wasting gas. Make it 12-15CFH maximum. Also, if there’s a collet body under that cup and not a gas lens, get a proper gas lens. A #6 cup is the edge between using a fillet body, and needing a gas lens. The turbulence of the shielding gas gets winky with 2...

This is the results of 180 amp / 200 freq / 75 balance/ 15 CFH argon @ 3 seconds My cheap o'l temp gun showed the pieces ~160 degrees https://live.staticflickr.com/65535/49898736001_980e399aa5.jpg 20200515_140318 by Doug Wei , on Flickr That just doesn't seem right to me. The few times I TIG'd 1/8&...

Not doubt you're correct - something I'm missing. Best I can describe is on the first weld hitting it at 180 amps it takes 3 seconds for the following to appear. At this point I'm not even holding a filler rod I'm just trying to figure out when it starts to pool.... A little history first. This had ...

Thanks! Again... The machine settings used for the above photos. Amp - 180 Freq. - 200 EN - 70 Argon 15 CFH The arc is as close as I can get it w/o touching - most of the time. :D Torch angle is pretty much perpendicular (filler rod almost parallel to joint while maintaining 90 degrees between fille...

The shock is from arcing on your filler rod and not the metal. Thanks for that bit of info... Actually I have finally figured out what the problem is! I suck at cold starting 1.75" x .125" square tubing!!! It is not a ground issue - if it ever was. It is not a "dirty metal" issu...
