When attempting lay wire technique the filler just melts and runs away from the puddle.
What am I doing wrong please?

I think you'll need to be more specific to get good answers.
Amps, thickness of material, torch angle, filler size, type of weld, etc.
I've never done lay wire for aluminum, only steel.

Tried being normal once, didn't take....I think it was a Tuesday.

I started by laying the wire and kicking pedal...got the same result.
Now I start the puddle then scoot the wire in and lay it. I move the torch and work the amps with the base my main concern. The wire melts and joins the puddle.
If I go too fast what you describe happens.
The wire is easy to melt and close to the arc. That makes the start a bear. Fun technique with practice.

Stone knives and bearskins.....and a NEW EVERLAST 164SI !!!
That's my newly shared work welder.
At home I got a Power Tig 185 DV. Nice, but no plasma cutting... Nice tight arc after a second.

Once the puddle is established and filler added to advance it slightly, end of filler is placed at the fluid
toe puddle-either right or left side, to create a melt path to the puddle.
With heat management, torch motion & angle, the puddle is advanced while continuously being fed by the filler end.
Filler is advanced some, into the puddle zone. As others mention--lay rod or lay wire requires 'a little' bench time

Torch angle is critical on aluminum. I have never tried to do laywire on aluminum. The laywire method uses a torch angle that probably wouldn't work with aluminum. You'll melt the filler before it hits the puddle. Hope this helps! Maybe someone with more experience chimes in!Greybeard wrote:.125" 6061 cleaned & brushed, 3/32" filler, T joint, amps were up there but forget precise setting, working the pedal anyway.

And your arc is right at the front of the puddle?dave powelson wrote: In the above pic, the filler end is melted and drawn by capillary action into the puddle--puddle's literally

By this time the rod would be half way up my glove!
I know... "practice "

....No, if arc was at front--filler end would melt away.
For bridging this gap, I suspect torch angle was pointed back at puddle.
I use a CK flex lok torch, adjusting as needed, without wondering what the torch attitude
and angle is, since I'm not instructing.
There's no back and forth, dabbing--the puddle's being worked and advanced, while
the rod keeps being fed into the puddle. It's a fast way to run a joint, faster than dabbing.
By this time the rod would be half way up my glove!
