DC stick amperage needed for general farm repairs.

[MinnesotaDaveChalmers]

Anyone know of a cheep and good 160 or so amp stick and lift arc tig welder?

My ESAB 161 is a very good one - it is just as good as my maxstar was.

I only sold it to buy the ESAB because I had the stick only version of the Miller.

Tweco makes very nice multi process machines too.

Dave makes a good point. For a few bucks more you can also mig.

NOW we've started you down a slippery $$slope$$.

I like my little Tweco.

My field welder was a 10 hp Generac portable, 5kw "standby generator" powering a 200A ACDC Model 130 Miller stick welder. I used 3/32 6011 rods; anything larger was a waste of time. I was welding 2 ⅜ Sch 30 pipe or steel purlins and it was all I could do to get things stuck together; even had to do it on AC to get more amperage out of it for what was driving it...obviously the joints were horrible, not pretty but functional. Later on I managed to get a 6500w 16 hp power unit (standby generator) and that was enough to do it right. Always wanted one of the fancy all in one professional grade but I'm retired not and that window has come and gone.

Now how many amps did I get out of it??????? Well if the source was 5kw, forgetting losses, and the arc voltage was 40v, then 5000/40 is 125 amps...factor in the losses and probably around 100. So your 130 number is kinda iffy, but if that's all you have, just crank the amps all the way up, use the AC function and she'll deliver what she can of that max selected amperage. Then ensure that you use the smallest diameter, easiest welding rod you can find. I think on the rods the 2013 and 7018 tied for a close second but didn't penetrate all that much......course I didn't need all that much. I think the 6011s in 3/32 were easily obtainable and the others seemed to stop at ⅛" as far as availability around was concerned.

I just got a mufti process machine that can do mig, stick and tig. Got it primarily for portability, weighs around 50lbs and has 110 and 220 plugs. Max amps is 220 with GMAW. Can run off my 10k watt genny for pipe fence (stick). As some nice features, inductance, run in, arc force and hot start.

This is a Lincoln electric 210mp runs around $1k and comes ready for stick and gas mig. Aluminum spool gun and tig separate.

As to your origional question, with this machine, you dial in your process, steel thickness, electrode and it will set your amps (ballpark) and you fine tune From there...

I keep coming back to where I started. I was looking at the Power Arc 200 st from Everlast. It has the lift arc tig and stick with 60% duty cycle. Have heard good things about that welder and it is only $349. I had thought I might save a few $$$$$ if i got a 160 amp welder instead but I have not found that to be true. What I want is the PA 200st but if it were in 160 amp for less $$$ I would lean toward it. Money is Tight and other things are not helping right now. Thanks Ed

I would go with at least a 200-amp welder for SMAW. It is nice to have a little safety factor with the welder. Just say you get into a project that requires you to run 5/32-inch 7018 one after the other.
In time you could pick up a Tig rig, and maybe find a good deal on an LN-25. Pretty much all your bases would be covered then.

For what you want to do, I think the only difference between the 160 and 200 is gonna come down to duty cycle. With 1/8 rods, its rare to get to 160a or more. But lets say you are burning some thicker stuff and pushing near 140-150a. The 200 isnt gonna cycle out as quickly as the 160.

Here are some photos below of what my little 160 amp welder can do. If you wan to weld 1/8 inch material, I can't see why a 160 amp welder would not work for you. Below are stick and TIG projects done with the little PA160 Everlast

Not to derail the thread, But was that the old kubota bucket or the new kioti? or someone elses? I must have missed a thread where you fixed that....or did you not post one? Whatever loader it was on...how did you manage that?

The old Kubota bucket. In examination of the original weld, in my opinion it was not welded properly at the factory. The other side of the bucket had much more weld metal in place than the side that cracked. I am not sure when it cracked, as there was a lot of rust in the crack, and must have been busted for some time. In any case, I just ground it out and welded it back up, and it has held nicely ever since. You can follow it here on this thread.

I see....you were using it on that big bad kioti loader:laughing:

I do think I remember reading that post now.....eh....memory going to h3ll.

Ok....no more derail. Back to welders.

Look for a high OCV (open cicuit voltage) in a welder - easier to start an arc (especially for rusty steel) and the arc is more stable. A good SMAW machine will have at least 80 volts OCV in DC mode.
