Power of the PT

[woodlandfarms]

Well, love it or hate it, here are some results of roughly 8 hours of work. A before and after picture. Slope is around 22 degrees, with chunks that hit 30 or so... Besides the slope ability, I really like the turning radius and the front mower. Man it is an amazing machine when it works...

it is raining, so I am practicing welding... In the rain.. what the heck, no one liked the way I mowed ;-)

That's one thing i learned when moving to this area. If you wont do it in the rain then you may never get it done.

That's certainly an impressive Before >> After set of pictures...

I'm glad to hear that you're still impressed with the PT, despite all the minor problems you're having with it...

Amen! That's rule number 1 in the PNW!

I finally got the pictures download.

I said "Holy Crxp!", my wife said, "What?". "Look what that guy down in Woodland did with his BIG pt".

 

[Grrrr]

I'd say that is a pretty darned impressive set of tree munching pictures That PT's very powerful for it's size and manouverability

That is generally how I work... Welding lesson #1 of this weekend: shut the valve on top of the bottle when you are done (full bottle of argon disappeared overnight !#%&^. And airgas isn't open on the weekends to get another bottle.)

Did you ever spray soapy water on all the fittings from your regulator or flow gage to the back of the welder? This procedure will prevent this from happening. Turning off the main valve, and bleeding the regulator is standard practice. You probably wonder how I know this. I did the same thing a long time ago. I am using STARGON for the welding gas. Has a little bit of O2 in it.

I think it is one of the learning lessons all welders go through...

Just FYI, there are several different STARGONs. Make sure you get the one that matches what you intended to weld.
e.g. Stargon CS for carbon steel (contains O2)
Stargon SS for Stainless Steel (contains N2)

All the best,

Peter

I use the Argon-CO2-Oxygen mix. CS

I love this forum, there's so many REALLY Smart people on here.

Is that Stargon CS (O2 or CO2)?
I was thinking that the gases were primarily to shield the O2 from the weld while it was hot , hmm seems like i hear hydrogens a problem too i guess the O2 might scavenge that too.

 

[ponytug]

I can't speak for others, but I am curious and let my fingers do the walking...

The great thing about having a larger market is that there is room for enhanced products.
First there was argon shielding gas, which blanketed the weld, but wasn't great at keeping an arc. Then argon with carbon dioxide, came along and it was easier to hold an arc. Then people noticed that if you put a little oxygen in it, you could control the amount of Carbon left in the Steel weld. (Hence the CS)

There are a large number of mixes to get the best weld for the given conditions. I find the choices rather mesmerizing, rather like a deer in the headlights, but it makes for interesting reading, and it makes me realize how much I don't know.

Praxair have pages and pages of great information;
Praxair Shielding Gases
STARGON, STARGON CS, and STARGON SS are all trademarks of Praxair.

For those that don't know, you can use CO2 regulators on Stargon tanks, if you use the correct adapter. CO2 is a much cheaper gas for MIG welding, but you have a lot of spatter, and more clean up. I think Praxair is the only one that sells Stargon. Others sell the 75/25.

 

[MrJimi]

The others sell a product called tri-gas with simular properties and like J_J says CO2 will leave lots of spatter and no fun when it gets in corners

This is the mix of Stargon CS. verse 75/25

Mixture Composition %
Ar, CO2, O2
%
Stargon® CS Argon 90
CO2 8
Oxygen 2 On thin gauge base metals, the oxygen constituent assists arc stability at very low current levels (30 to 60 amps) permitting the arc to be kept short and controllable

75/25 Argon 75
CO2 25
