@ olek - in TIG welding, the temperature in a plasma arc column varies from the tungsten (cathode) to the material (anode). The reported values in literature by arc physicists, institutions, and industry are all over the map, but 6,000 to 10,000 deg F is a generally accepted temperature range for t...

There is the share my weld app that Jody put out but it I think it is only on Apple so far. They are working on the Android version. Thank you, I hope the development is not halted. No information after June 2016, looks like they had problem with the storage provider, and needed to find another. (p...

I heard of a collaborative cell phone app allowing to take pics of welds, along with most or all the parameters used I take pics to record my progress and keep memory of parms, an app that could put the data in a database would be easier than my actual method (pics need to contain writings with chal...

At first I was looking for the information on the temperature within the arc, and the French Wiki stated something about the same as the torch, with a computation based on the volts/amps watts result, it seem to be only the temperature of the electrodes at the begin of the arc, the arc itself have c...

https://hypertextbook.com/facts/2003/EstherDorzin.shtml That is a good overall chart on temperatures. The torch is typically less efficient. I had a discussion with my welding instructor about welding chromoly tubing and how when he talks to old guys they say torch welding is the way to go. sure yo...

Hello I was surprised to read that while my OA flame is 3150 degree celsius at its hottest, to get to 3000 celsius with arc I would need 200A, (for 23v) and then only a part of that heat is actually used, more or less depending of the process. (stick would use 20% of that heat only?) That 3000 celsi...

Hi there, You don't need to weld. Do this. https://www.youtube.com/watch?v=w62c4NQDwP0 Please excuse any swearing in the video, hes very smart but rough around the edges. Watch with the sound down if need be. Mick The same , but without the grease part, using just the central part of the extractor ...

Did you hear of people making a derivation to obtain a remote control (amps) from an inverter? Mine have a contact type + and - no potentiometer. I wish to make a "box" if not too difficult ... (with a little help from my friends [​IMG]) The model I have is a PROGYS 200E FV CEL http://www....

If you liked your old 9000 series you will love the 9002 NC. It has the TrueView technology and the shell is exactly the same as the old 9000 with newer headgear. You'd be hard pressed to find a better helmet at the $200 price point. If it was for me, I don't think mine is speed glass series. I fin...

Vertical down 7018 is incorrect. Keep practicing, change one variable at a time. I prefer 120-130 amps for stringers vertical up, 1/8" 7018. Weaves I may run lower depending on steel thickness. Why weaves may run lower ? Weaves have a slower vertical progression than stringers so more heat get...

Vertical down 7018 is incorrect. Keep practicing, change one variable at a time. I prefer 120-130 amps for stringers vertical up, 1/8" 7018. Weaves I may run lower depending on steel thickness. Why weaves may run lower ? I seem to discover quite the opposite, making small "hesitations&quo...

Nah, no peeking. A trick I learned for fixed shade helmets is to find your mark and set the rod a little to its side so that it sits on the flux and doesn't strike, then put the hood down, pivot the rod up and strike. Thank you Pete, that is exactly what I was after , simple but efficient. So for i...

Vertical down 7018 is incorrect. Keep practicing, change one variable at a time. I prefer 120-130 amps for stringers vertical up, 1/8" 7018. Weaves I may run lower depending on steel thickness. Keep reducing amps until you get a puddle that is too cold, then increase as you are able to control...

https://weldingengineers.co.nz/images/Beta_90_Lifted.jpg If some one have a good trick.... I think of using a thin piano wire as a remote control (attached at my wrist for instance) But if I learn how to hold steadily the rod without touching and with one hand .... They talk of a "peep" p...

I use an older model from 3M (not sure it is in the speedglass series) , it looks like that model from Kemmp, exactly the same, but the air flow is the 3M Jupiter see http://www.soudeurfrancais.fr/?page=kemppi_beta_90x_fresh_air_spares I baught that second hand for painting and lacquering (for the J...

Thank you. It is clearer..

After an e-mail discussion with a HELPDESK@lorch.eu, I realized that there would be another pcb-level manual service for those inverter component modules relative to that handbook in German but he haven’t the permission to send out detailed electrical schematics of the pcb’s...so i think the only c...

Thank you, I see.. 17 torch is a standard name for valve torch? Are all body size the same? Can I mount a large and a thinner buse and tips on the same torch? Even if those need 2different gas flow?(just want to know what do I need to buy) Once valve closed, no leak is expected, but I suppose we clo...

I own an MMA welder DC inverter with tig lift option and end of arc regulation (PROGYS 200 FV PFC CEL) I like to use the tig function to make small tools gigs, etc Some people said me that we use much gas when using those valve torch, I do not get why , can you tell me if that is true ? DO I need to...

I was said that whip and bead would cause inclusions or discontinuities if done with 7018. As I get it, when using 7018, the rod do always stay at the edge of the puddle so that motion should not work I think But , will it be possible with the 'rutilo cellulosic' types (strong percentage of cellulos...

Well gentleman at school we only have 1/8" diameter arc rods classification number 6010, 6011, 6013 and 7018. Now these rods are all 1/8" diameter. You may want to ask advice but when making beads side to side the useful exercice is to cover the precedent bead by half. You are reassuring ...

Higher amps will flatten out your bead. That also did "jump to my eyes" looking at the shape of the beads. Seem to me 7028 run better with amps in the high range, but with a 'slow advance' as with triangle up, 80A did do well with 7018 2.5mm (and I had not to go too slow). thin steel, 6 m...

There ya go! Mistakes are only bad when they become something that holds one back. The good ones see them as "what to work on next". Hello, after 20 days without training, and after mounting that amazing gold plated glass, I was surprised that I did feel comfortable, managing the puddle w...

Hello, at least I think I know what I want to see. So it is a big help. And you where right (of course!) Easier to work on consistency with Z (despite the puddle less visible) What do you think ? https://photos.app.goo.gl/jHDKwXcxVUWCX7H23 I am terrible student as I begin doing my mistakes before go...

Best bet is a cutting disk. Whether it be a large 14" abrasive saw, or a thin 1mm cutting disk on an angle grinder, you WILL have metal dust to deal with. Its just not something you do indoors. You still need a small polishing tool to get the fine scratches out to see the etch. Do you have an ...
