    The other display should have a numeric code that specifies exactly what the welder is shutting down for. Your manual has a nifty chart that explains what to do for each of the HLP codes.

    Regards,

SOURCE: 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.

SOURCE: I have a miller microwave 200. what settings

I think you mean you have a Miller Synchrowave 200.

Typically, you would want to use AC below about 250 amps. In this case (to keep it simple), use AC, adjust your balance to about 4, use an 1/8" pure tungsten, pure argon at about 20CFh, and set the panel at 170amps to get things started. For general purpose, use 4043 filler.

Now - these are just generic settings, but they will get you going.

SOURCE: why is my arc unstable when I start Tig welding? Sometimes it starts nice and smooth and sometimes it blasts really bright and flashes me.

The tungsten point has to be quite sharp, the gas has to give constant flow relative to the tip size and shroud and the amps adequate to create a spark without immediately making a mess of the parent metal. The two most common issues will be the cleanliness of the parent metal and the Gas flow. Assuming you have all this set up, it actually sounds like you have a problem with your mask as you shouldn't get flashed at all.
I had a similar problem once with a solar powered auto mask because the batteries had died and wouldn't recharge. I retro fitted a couple of button cell 2032 to the mask and it's working fine.

What are 4 common welding processes?


There are four common welding processes utilized through out the work industry today. They are :
(Stick Welding or SMAW) Shield Metal Arc Welding
(Mig Welding or GMAW) Gas Metal Arc Welding
(Tig Welding or TMAW) Tungsten Metal Arc Welding
(FCAW) Flux Cored Arc Welding

There are many many welding processes, however these are the most common. The type I am going to discuss briefly today is SMAW. The most economical and cheapest way to learn if welding is for you or not is to start with stick welding. It has the least amount of variables that can go wrong for a beginner. It is not fast paced like mig or flux core, so you have time to watch the molten puddle to see what it is doing and make necessary adjustments to correct the size, shape, and contour of your weld bead. The hardest part for a beginner is to keep the electrode from sticking to the work piece. Thus is the reason it got the name of "stick welding". There are three common ways to strike an arc in SMAW. Tap Start, Scratch Start, and the last is to place the electrode upon your fingers like a pool cue, and shoot the rod like your playing pool.

Why does welder stop feeding after short weld


Check to see if the wire feed pressure is set correctly. Sounds like it's a little loose.

WHEN I TRY STRIKE AN ARC WITH A ROD YOU HAVE TO HIT IT 5 OR 6 TIMES TO GET IT TO WELD ITS HARD TO KEEP IT GOING BUT AFTER 4 OR 5 SECONDS IT WILL BURN LIKE NORMAL (USING PROPER AMPERAGE)


Is this on new rods as well as one's you'be been already welding with? Depending on rod types, some will "flux over" the end, after welding insulating the tip. When you're welding at a low setting, with a small rod, sometimes it is hard to start an arc. A 7018 rod is a good example of this. Strike the rod like a woodden match, or drag it on the metal, to expose the rod. It also depends on your welder. Some have settings to help start an arc and then control the current. Older transformer welders arn't that smart and are less forgiving on low current thin metal settings.

Bad tig weld job


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
