Day 4 Everlast 325EXT

[SteveY]

Still didn't get my hood, I'm flying half blind, but just trying to check everything out!

More AL checkout!

1/8" 6061 piece of AL
Very upper #1-4
Straight AC, advanced Square @ 130A

Fair enough, as it should be

Checking pulse
Lower right two attempts
First at 130A nothing but trying to clean
Second 200A, no filler, about right, cleaning and metal penetration (concave dimes)


Top bead set Advanced Square, 30% Peak, 15% Backgound, 1.2 pulses per sec
I see where this is going, need to experiment with settings, everyone on net has different settings.

Torch is getting hot, AL is getting hot!

One more try, lower left Advanced AC Pulse (AC/DCEN combo)

Holy crap, when the second half of the cycle (DCEN) kicks in something is going to melt

Using 4043 1/16" filler melting before hits the puddle
Had to use a kinda lay technique, lay filler on AL and slide forward into pool and then back out, quickly and keep torch angle nearly straight up
Will need to change to 3/32" filler

Everything is overheated
Touched glove to AL and melted a hole in it
Water cooler and torch next
