No High frequency on plasma cutter

I found a forum addressing the welder you mentioned. They are amused, as you will be, by the manual. https://dl.dropboxusercontent.com/u/11148130/MishtoWelder/MIG200.pdf
It is ridiculously useless. Try taking your welder to a high school shop teacher or find a local hobbyist welder -- because welding supply stores hate these Chinese boxes that cut into their sales and will not be helpful.

Could be as simple as having the ground cable connection placed into the wrong port on the front of the machine. Foot peddle/machine selection switch in peddle mode instead of machine mode? Internally it could be high frequency spark leakage or failed HF circuitry. These are the most common causes of spark failure. Oh and be sure you have good consumables and they are installed correctly. Air pressure leaving the torch head should be around 70 psi.

check fuse, or other loose connection

check first the pilot arc, if air pressure is there or not.next check solanoid valve working or not

Sounds like the problem could be with your tig torch. Inside the tig torch you have a copper cable which carries your main welding current. If there is a break in the copper the high frequency is of such a high tension voltage that it can jump across the break in cable making it appear that your tig torch is fine. If you have a multimeter check continuity from one end of the torch to the other or try another tig torch.

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 !?

yes it does matter.each brand is set up for their own torches.

Check high voltage transformer and capacitor, also check point gap circuit to ground.

Try this one if not it go to the next link for manuals.

check to make sure all torch parts are in good shape and is put in correctly
