Dear friends happy new year everybody. I have this mask optrel p550 older model and I am not pleased with it.The switching time between light and dark I think is rather slow and is causing stress in the eyes espesially when there is a lot on and off.Perhaps worse in dc mode.Does anyone knows anythin...

I say yes I agree.The discription is perfect.I would say the picture is rather misjudging me the weld was very good.I boil every detail out carefully it took considerable time.It is always better to win than to lose.

eventually it was aluminium cast I was mistaken that was very heavy.I welded with easy with 4043 1.6mm rod with #5 ceramic plain tig torch set up.It works very well and I highely recoment to try out.(I have seen it in one Jody's videos and I am very pleased even in lower cleaning settings.I did a go...

Thank you, very informative, what about welding is it possible with tig?

Thank you,can it be welded you think and how.Also can you tell few things for antimony.

Salute everybody.This is the case.Does anybody can tell what metal is it.This is a part of an italian scooter.Looks like aluminum but seems heavy so it might be antimony.

There is this metal that seems still a mystery ,how do indedify it and what it is.

I admit that a new freshly grounded well shaped tungsten makes things a lot easier.

It is a new modern bike , here in Greece there is not the variety of your market so no ER70 -S2 or similar.I usually mix steel or iron type metals no cast iron with 304 and the and it works well for now.I have tried a[u] tig rod for steel and it foams like bubbles like boiling with very bad porous a...

Time is the moving picture of the unmoving eternity ( plato) as you already know I greek and I like philosophy.

Out of many choices chose the right one.I am sorry that I can not provide a picture I was under lot of pressure.It was a Japanese motrocycle frame.I usually weld mild steel with 303 , 308 ,309 or 312.If I use simple iron tig type welding rod seems that base metal boils or foam ?. I did not had prope...

There is always the risk of overheating which can cause bad coverage symptom.In future as it seems a science fiction now.A sensor will inform welder real time the temperature of metal welded and refer to machine to lower amperage automatically so overherheating will be avoided.This is particular imp...

Thank you it is a good comment to know I tried with new tunsten and still Im not sutisfied.Seems wider cup is needed that I try soon.
Why then in titanium a hudge cup is used?.

I usually use 6 ceramic cup , gas lens .2% lanthanated 2.4mm with 7.5L argon . in aluminum and I am almost ok.Same settings to Iron or steel do not work, seems a lot of oxidation takes place without any improvement if I change a little the gas flow.Does it need bigger ceramic nozle?Any advice will b...

This is about well known subject , but I would like to make a little note . I have a bench grinder hat works fine , but it is nice if you grind the direction of the arc travel . So i turned opposite the direction of rotation of grinder and things are a lot better . Grinder turns opposite the usual g...

I had a similar case and i had the same problem there was no way to make it decent . So i switched to oxygen flame with traditional bronze and flux .With adequate heat the result was a lot better. It was more soothe and fluid with better adhesion to basic metal seems that in aged metal no matter the...

The whole procedure took many hours and it was given all possible ideas for
solid welding with a lots of rework . I did not do a lot of grooving since i grind it
to fit.It was only 4 millimeter thick and i did both sides .Now i keep fingers crossed
as you use to say or pray to work.

It was hard work I did anything I knew to make it work decently , I took some pictures
of different stages . The rod is 5356 the metal was a little porous so I had to rework
or wash welding so it will be good . Im not proud but it ok

dear monger and the rest there was a delay but here it is

You advice will followed to the letter except the whisky since i will not follow the crack but the floor. Usually the game is lost becase the patience needed to do this kind of job the motorcycle engine I mean . The difference betwen success and failure is a tiny detail that usually goes unnoticed s...

Definitely will not be repaired , too much the risk the metal is burned and contaminated due to overwork in a form of badly "washed" technique , there is not time for shizz and giggles but you are correct it had no penetration weld was like decorative rather than it should had been.Metal f...

i heard the someone uses 5356 in a thick cylinder head block where cavitation from
cooling water occurs , do you think because of the heat should not be used .
I informed customer today that bike frame cannot be repaired.

There are some greeks around don't worry about them
