Lift your whole wrist/arm up as you move through the weld to keep your stick angle good and prevent reaching with the electrode. That will help avoid long arcing and porosity.

And yeah, those gold lenses at #10 din will be like a whole different ball game for seeing what is happening. Will likely be a significant improvement.


Depending of the size of the electrode (here I mostly have 3/32 7018 left so no much choice) I may decide how large my motion will be, as because ther is no direct heating in the corner, the sides should be near of it enough (?)
I also try to make my left right motion whith an advancing into the corner, (sort of horizontal V ) so the arc lenght is kept the same; Is it a good way of doing ? (I am thinking, may be the longer arc when going right left allows to keep some heat into the corner, so the weld will flow in it naturally, in that case keeping a constant arc lenght will be counter productive (?)

Thanks, I am not sure I understand, I move my hand arm etc so the rod is always pointing the same direction

I did try to make a small left to right move with the wrist but as the angle change while the stick is wearing I am not sure it is advantageous

I will try to make one with the best arc placement today (I had too much undercut at the begin pass yesterday, I forget arc force it was at 20% but enough to stiffen the arc apparently

When mounting, is the goal to recover a little the precedent bead as when padding ? The precedent bead is cold at the moment I come back on one side. (I tend to place the arc at the apparent thickness of the precedent bead )

So really Z wave ? I find "natural" the feel when making a small arc (inverted smile) I suppose it allows more cooling under ?
But also with smiles extended as a small J letter, I was told this is the way for 3G with 6013 while reverted smile is good for 7018 , which one is flowing the most ? (or it is only because of the more present slag, smiles and J allow the slag to go down, while with the inverted smile 6013 would run in the precedent bead creating inclusions.

for the christmas tree my instructions are : begin at the right side then go immediately left and then move a little the angle to go in the corner a little higher with a little pause in the corner, then again right left , etc AMps 2/3 max of the ones on 1F .. (I guess the rod almost 90 deg horizontal for the sides) the intention is good penetration in the angle, as this is done with only one pass, no more beads, it may be considered a gain of time.
I probably can lower heat more, if I consider the 2/3 I may use 65Amps , I will give a try it may give better control, but the arc force may be necessary may be at 10 20% as sticking will be the norm ;Regards)

Thanks all for your encouragements, it was worth doing some training each day or almost

Thank you , is not 3G in a V between 2 plates, with a root and a back plate ?

Appreciate your comment ;)

Possibly pausing in the corner is only for mig.

Esab shows a 'Christmas tree' with pauses on the walls

They say to try to move the angle do the rod do not wear in angle too much on the sides (it must create gas protection problems when passing the other side)

Those types of movements are too complicated to develop any type of consistency.

Think Chopsticks rather than Rimski-Korsakov.

Ah "CA ME PARLE ;)" so no exhibition for tonight ?

I will play you "tinkle tinkle little star" at my best !

btw I did not get turn your hand back and forth" , I move the whole arm usually , better move the hand only ?

cheers

Hello. Here is my personal version of "tinkle tinkle little star " (anon. early 20th) ;)

4 movmts :

1 CALMO
2 ALLEGRETTO MA NON TROPPO
3,ADADGIO
4 ANDANTE,

AD LIB.

CHEERS!

PS esab 48.00 3/32 90-93A no arc force (a little too much amps it worked better at 87-88A finally, quiter for me also)

II did make Z then progressively raised the middle,

BTW it can be seen in the weld but I finally had the view of the puddle moving from left to right and vice versa (I mean the cooling of the puddle of course)

Keeping that in mind should help when making less large Z or inverted U (when I go up for the U I see the puddle better for a small instant) not always as easy as I thought to see well (particularly if no "puddle" was done at the start.:()
The light of the 7018, while less shining than 6013, produce a high contrast with the puddle that make the eyes tired?
You also have days where the eyes are in less good shape? I understand the use of lcd then (and for many occasions where a lighter filter is better)

I made a little more verticals, and some 6013 descending, trying to have some thickness.

Burned my pants is not it a certain sign of good progress?
