Kiwi is right with moving up to the 1.5/1.6 at least. The vibration is going to wreck that thin stuff. It will be a tricky weld no matter what. That plate will need some heat so make sure your arc is focused mainly on the plate. Then move quickly toward the tube and get moving along your joint.You w...

How much are you paying for the Thermal Arc? It has a low duty cycle even at 150 amps. Go to the Everlast site and see the prices of their machines. You probably can get a stronger machine or at least one with a way better duty cycle to Tig with. 150 amps will work because the tubing is so small and...

:?: Would an aluminum expert please educate me on why when I use my 3/32 tungsten my torch runs a nice shiny bead. However if I change to a 5/32 tungsten I get dark digging gashes. All torch parts are brand new with both tungsten. Tungsten are new. Amps do not make a difference. The more silvery loo...

Thx guys!

Thx. I'll give that a try and get a new tungsten wheel.

Power tig 250ex machine. I wanted to weld a 3/16 to 1/4 piece of aluminum plate to a piece of round tubing 3/16 thick wall. I set my machine back to ac with pulse at all the same settings I had when I was welding some 1/8 inch wall square tubing. I increased the amps of course. I grinded the metal a...

Thank you for your time! I'll be shopping around tomorrow to see what I can find according to your advice.

Coldman,
I looked up split air conditioners. Would you have a brand to recommend?

Thank you for your time! It's highly appreciated! Can't wait to get to my shop in the morning!

Coldman,
Portable unit. Closest corner 6 ft. Distance from top of machine to top of wall 5ft but no drop ceiling. Wall height 8 ft.

So you don't tig weld aluminum?

Ace,
Haier 14000 btu ac,heat and humidifier. Model HPN14XHM. Brand new. My shop is 14x14 with a ceiling peak of 11 feet. No flat ceiling at wall height. It's open to the peak. I have r13 in walls and r38 up on ceiling. R38 is up against metal roofing. Thx!

My wife and I were out fishing and tied off to a big red bouy channel marker. While fishing I told my wife, those welds don't look that great! But I'm sure that marker has been out there for years.

I built a welding shop on my property. It's 196sq ft with a peaked roof with the center beam 3 ft above the 14x14 shop. Hope that makes sense. I bought a 16000 btu ac,heat and humidifier portable unit. I insulated the ceiling with r38 and the walls with r13. I have a metal roof. I figured the ac uni...

10-4! Thanks Len!

Braehill, Thank you for the info and your time! I'll stick with stainless. Do you use the screws so your able to change the hinge in the future vs using rivets?

I am looking to rivet stainless hinges to aluminum. I understand the nylon or other material barriers behind the hinge but which of the suggested materials should i apply in the rivet holes and on the rivets? I found aluminum piano hinges, would these hold up as good as stainless so I don't have to ...

Thanks fellas! Would the 309 require purging to stay strong or would it be fine without for standard exhaust pipe?

Quick question: What would be a good stainless steel filler rod for regular steel exhaust pipe? Or should I stick with er70s2? Thanks!

Awesome thanks for the advice!

Minnesota Dave and Oscar, finally had time to trouble shoot my tig welder. I searched for leaks all outside the machine and nothing. It looked like a huge pain to open my welder so while looking at the end of my torch I decided to change the only piece I hadn't changed yet to get better flow. The pi...

I would get the Everlast Powetig 325EXT. Its in the 2,000 dollar range, 245amps at 60% duty cycle. 320 amps at 35%. I have the Everlast 250EX and its duty cyle is 250amps @ 60%. My machine has a very nice smooth arc. I have been welding 1/4 wall steel square tubing at 230 amps and can continually we...

No time to check leak yet. Hopefully tomorrow.

I've checked the line around my regulator and drying filter. I'll get the old soapy water out and check the rest. I misspoke, I grind to shiny bare metal with a flap disc and bevel the edges. Thanks for all the help. Let you all know tomorrow. A leak is definitely better then a machine issue.

Ok. I can't till tomorrow. I'll posts the results. Thanks for the help!
