Wow you have a lot of variables here. Let's go over some of them.1.AC current 2.100%argon shield gas 3.Check your Tungsten, it must be the recommended 1or 2% and the right size, clean and the tip rounded by meting 4. High freq. turned to continous-not just "START"
5. CLEAN,CLEAN,CLEAN your Alum. with a S.S. brush that has touched NOTHING else in in it's life!
Start here and GOOD luck

Have a Miller Dynasty 300 that won't tig weld, displays HELP 12 code. Suggestions??


Some welders have a resistor that is obvious and accessible but to give an error code it is likely something else inside. You'll have to look at the circuit board for a component that is burned. If you are lucky you will find a fuse.

Lincoln precision tig 225. Makes bad aluminum welds in AC. Welds show signs of contamination. Have tried new argon bottle. No leaks in gas lines. Using pure and 2% thoriated tungsten, 3/32, pure...


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).

Hi, starts to weld fine after a few seconds hi


It sounds like you need to change out your SCR chip on your motherboard; Miller makes one that i have installed on all our 350xl's, I don't have the number on hand but i can get it for you tomorrow.

Have a linde hda 300 welding machine when in the tig mode with remote control foot pedal the current control goes from 0-100 no in between control


Your foot pedal should adjust the current, just like a sewing machine. If it is not working either the foot pedal is broken or your welder isn't compatible for the foot pedal. Some welders are only strike starting with no variable control amperage (usually your lower end models).

Linde welding machine when welding in tig mode foot pedal will not control amphere output it goes from 0- 100 no in between


Check to see if the remote switch has been set, or if you have broken wire in your pedal lead. You might even want to open the pedal housing and take a look see. I've had more than my fair share that the contacts inside the pedal housing were worn or cooked. Good luck, hope it helps

How to TIG Weld


TIG stands for Tungsten Inert Gas welding. Also called GTAW (Gas Tungsten Arc Welding) and HeliarcĀ® which was Linde's trade name for the TIG process when it was introduced many years ago. The arc is started with a tungsten electrode shielded by inert gas and filler rod is fed into the weld puddle separately. A slower process than MIG, it produces a more precise weld and can be used at lower amperages for thinner metal and can be used on exotic metals. TIG does require quite a bit more time than MIG to learn. It is similar in technique to gas welding.
