Tig will work normally on aluminum for a few minutes then will cut out and the only way to start it again is to scratch start it but then it will only work for a little while

This seems to be a duty cycle of the type of welder you may have,the other thing im thinking you need to be in continious cycle mode ,theere should be a switch allowing continious cycle also the main switch should be on ac mode for welding aluminum. the tungsten should be 1% with a green paint on the end .you mention you have to scratch to restart the welder you have might need a high frequency box of its own that also hooks to the welding machine, small amp welders have small duty cycle which means it will shut down if its getting over worked or hot good luck

Hello; Make sure AC Auto Balancing is Enabled; And when Welding Aluminum Aways use 100% Pure Green Coded Tugsten.Make Sure you dont have 75/25 or possibly if you know for sure your frequency balancing on your machine is working you could possibly have a bad bottle of gas try the bottle of gas on the machine that you say that runs good if it runs good put it back on the 225 if the problems still exist there is something wrong with your machine`s Ac high freqency Auto Balancing.Make sure all connections are good,check tig head for loose connections. Step Up to A 1/8 size tugsten it will carry more heat and gets less contanimated.Every time you stick your tugsten it will run contanimated untill you burn it off or clean it ,if you stick you tugsten go ahead and put a clean piece back in the tig head, Contanimated tugsten wil run dirty for 5 to 20 minutes Untill you BURN it Back Clean !?

How too set up a tig welder for welding thin steel?


DC current, electrode negative (DC Straight, DC-), High frequency for start only (really don't have to use high freq at all for steel but it helps establish the arc without scratching), 1 amp per thousandth of material thickness is a good setting to start, adjust from there for the job. 1 amp/thousandth also applies to aluminum- it has a lower melting point than steel but conducts heat much better so power to weld is very nearly the same.

Use a sharp tungsten, don't ball it at all (as you would for AC work).

I have a Miller Synchrowave 180 sd and have been having difficulty welding aluminum. Can you please help.


I'm not sure what it's doing to know why it's not working but if I was trying to weld aluminum I use 100% argon in ac with high frequency continuous and a 9 second post flow with 5356 crown weldind rod.

Lincoln 185 TIG pulse control inadvertently kicking on and off.


welding aluminium requires a bigger current draw that with steel and to weld aluminium it is a dc current requirement
what you are seeing as a pulse may be the unit going into overload

How to prepare tungsten for aluminum for welding aluminum a ball is supposed to be fashioned on the tip of the tungsten electrode how?


To make successful aluminum welds you must set your TIG machine to A/C, so make sure you get a tungsten rod meant for running alternating current. If it is pure tungsten (green band on the end), you're good. For the tip, just grind a tip like you normally would. When you start welding a bit of aluminum will collect on your electrode. After that you may need to break off the tip every now and then if you get a lot of junk in the ball. Make sure you practice on some scrap first, aluminum is very different to run than other metals. Getting the right operating temperature down is a bit trickier too.

Just in case you're working on something serious like a motorcycle frame, make sure the aluminum you're using is a grade that's able to be welded. I've heard about a guy that built costom bikes and used the wrong grade, when the customer took the bike down the highway it fell apart on him.

TIG welder help


Choose the electrode to use for the project you are starting as well as the variety of alloys you'll use such as the 6061 Aluminum alloy electrode. Grind the electrode to a point. Try to create a tip and sharpen it to help it become more rounded as you weld. Place the electrode into an electrode holder with the tip about 1/4-inch away from the sheath. Choose the settings on your tig welder. The three main ones are AC, DCEP and DCEN. Choose AC for aluminum. Slide the "cleaning/penetrating" slider more to the penetrating side. Set the "air on" to five seconds and the "max amps" to 250. Turn on the gas. For aluminum, use pure argon. For steel, an argon and carbon dioxide mix. Scrub your welding table or flat piece of sheet metal with a wire brush to make it clean and flat. Gear up in full welding safety gear including hood, goggles, apron and gloves. Hold the electrode in your dominant hand and start your welding project. Check your settings every so often to make sure they haven't changed and adjust as needed.
