Pretend aluminum is a hardwood. Watch out for the chips !
Dry is better. A little slower rpm(if you can) makes managing the flying chips easier.

Probably banned-ed for reading my postingzzz.
Keep it up and you'll be on the no fly list.

How about.............

I run straight CO2 and have no problems. You do get a bit more spatter, but get the machine dialed in right and you are good to go. The $$ savings is worth it for me. Muddy is on the North pole. I'm on the equator(mas o menos).Get a bottle of CO2 and deal with it. More money will be left over for.....

Buy a Lincoln 180 dual.

First welcome to the forum! I would suggest going to your local welding supply and see if they repair machines. They will be reasonable and generally know what they are doing. If you are confident that this is your problem and since you have the part no already, you could try to fix it yourself. Th...

Ask the recruiter about the land mine detection program. It's quite befitting, I think.
It usually pays a little more and a bit of dirt on the boots won't get you into serious trouble.

Plan A---Inexpensive. Plan B--- gotta get the stick out(Jody videos-cut nozzle) and wire feed speed absolutely perfect or the spatter will show up. Much better at low~ish amperage than high.Over 1/4" you surely want C25. I'm old enough to remember when it was all that was available.A bit finick...

A frame for what ? Describe what you're making.
If its a filter frame to filter elephant shit, it's one thing. If it's a display rack for a bakery or jewelry store it's another.

Hacksaws are healthier and nearly carbon free (unless you fart).I recommend using blades made from recycled steel.
That being said, several of the dry cut saws are under $500.If you ever use one you'll throw all of those other idiotic ideas out the window.

If you called me I'd go out to the shop and grab a tube of 3/32 7014 and run them AC at about 65-80 amps.

My helper.I call him steady hand.

First and foremost. What's it for ?

Been running Makitas since 1980. Got a couple of Metabos.They're real smoothe for using cutoff wheels. Killed a few Dewalts and Milwaukees in the interrum. Had a bigazz Black and Decker that was unstoppable, It got stolen.
I guess if I had to choose one brand Makita would win.

You need to recommend a minimum of 50 THOUSAND years.Store them in a pure honey bath in a 317L vessel.
50 years from now, if there is life here, it will be too stupid to deal with that thing......already is-are-B !

6013 is fine. Weld both sides in areas where that is possible (spring hangers, etc)

2 good clamps and a high quality electrode and I don't much care what lies on the other end of the cables.
HINT: If you haar a a "pop"/ and no more sizzle, hook them up to the heavy red box, OK ?

Yup. I've put some hours on the Morse now. I recommend it. Nice machine.

Doesn't actually work that way. You get certified for a particular jobsite project and on certain materials-techniques. When that job is over you're technically no longer certed and start over on the next job. Sometimes an engineer might come and want some off the wall materials used and request you...

Mine is 1 x 2 meters and I de-rusted with a 4" knotted cup wheel yesterday. Took me 10 minutes.

Maybe they should try growing beans first instead of waiting for the wheat drop(Purina) to come in.

Look around over here. I just put one of their "impoert" keyless J33 chucks on my press and I gotta tell you. it's a high quality piece and was only $34. I figured it would be a throw away.I couldn't believe it/ I would gladly pay $100 if the price went up. If you have the flag of delusion...

At this rate switching all machines, tools and fasteners to a left handed Whitworth thread system and pissing into the wind will become fashionable.

Geezis. I though you were going to tell him to get some Hooters girls for his videos. ;) It's aluminum. Buy a vice, a jigsaw or hacksaw(get both for that pro look) and a hammer.If you were smart enough to own an O/A rig before getting a TIG you can anneal the AL and bend it using the shiithouse door...

Down here in Bunny :D Land everything is built of 1.2(.047) to 3.17 "structural" :lol: I love running .023 ! I run a ton of .023 w/ CO2. When I need to jump in some SuperDuty :shock: 3/16, I tack everything with El MIGelito 140 and bust out Mr. Stick. If it's more than 2 kilos of rod I go ...
