Not the most productive thing I can do with my Argon.

it was a fuse pass at 5-15 amps i forget the key is the tungsten i was using a .040 and sharped the shit out of it. that was the first one i did the seconded one i got it to where the weld was no more the 1/4 down the sharpened edge

Just got a Schumacher Mig welder. Now all I need to do is learn how to weld with it.

Burn, burn, burn.

Any tips for using a wirefeed machine for the first time?

I'll be working with 1-1/2" square 14ga tubing.

Amps

Feed speed?

How do I get a puddle started, do I just hold down the trigger or is there more to it?

Mig of Flux core wire?

Name the machine and I'll dig up the chart for it, I always start at the chart with some test metal and see how it does.

Here is a picture of my dads it is about 4’ x 6’ x 2”

That table looks like 2" armor from a ship. The second or lower level under that doesn't look very small either. Man... that would be one heavy mother to move. Must have been built in place or moved in my a fork lift.

Another table related question, how horrible would it be to take a wooden tool bench, place a sheet of concrete board onto it, then put a sheet metal top over the concrete board?

Depends, my brother is looking at getting a northern tool brand 135amp welder for some small projects. I may use that or my father in laws 180amp miller. Both are gas compatable but Im thinking flux core.

[P B G]

Well for example, I have a Miller 180, if you pull up the chart for it, they give suggestions.

For 14 gauge steel, Flux Core DCEN, they suggest
.03" wire 3.5/35
.035" wire 3/25
.045" wire 3/15

Of course those are starting suggestions.

With enough heat the concrete will pop.


2in carbon slab is the way to go. 81.6 Lbs/sq.foot

What do the second numbers mean?

Fps/amps?

[P B G]

Well I believe the first is just a 1-10 knob, so its specific to that machine. They call it voltage adjust, but it probably does just change the amp setting.

The second is the feed rate, but I don't know the units on it, i'll have to read the manual.

The table came out of a copper smelter

You don’t move that thing by hand. The other day we were trying to straighten a part I had it in the vice and had a 8’ bar on it, and I was jerking the end of the bar as hard as I could my boots broke traction with the floor but the table never moved. But you think that table is big, he has a Acorn table that is 3 1/3’ by 8’ by 8” (that is eight inches thick) I don’t think I have any pictures of that one
