TIG Amp/volt settings bobcat225

[Lone_Wolf8]

What kind of math am i supposed to be doing here to figure out the temperature i need to be at? I am tigging and cannot figure it out and cant find anything on the web pertaining to this. This is my first generstor welder.
any help i s greatly appreciated.

Figure approx 1 Amp per thousandth of an inch thickness of the material to be TIG welded.............

in CC Constant Current mode..... DCEN ( Assuming Steel )

Valve on TIG torch.... 100% ARGON 14-19 CFH ( depending on torch and cup )

My real question would be....what is best way to figure out what temp i need to be at. If i want to be at 90, do i choose 50-100 and #8 on the dial that goes 1-10? Or 70-150 and ?
How do I interpret the dials?

NOT TEMP

0-100% of the selected Amp range

I've been practicin the "Looking through the gap" technique for the past week or so. I was getting good penetration after the 2nd day.
So, I layed off of it for a week and have been at it for 3-4 days now and I'm still getting a suckback or flush look on the penetration. This is only on the bottom portion from 5 to 8 o clock. I can't figure out what it is that I'm doing differently from when I first starting practicing this.

sounds like heat soak...... a problem when you have no pedal to taper back on the heat

you could speed up to keep up....or skip weld to control heat

The amperage control is percentage of the range selected. So what I do is take difference of the range and divide by 10. Then each dash on the amperage range is equal to that amount. For example, given your dials from the picture and assume you're using the highest range (85 to 225 amps). 225-85=140....140/10=14 (each whole number is then worth 14 more amps)....starting at 85 amps (knob all the way to the left), then add 14 amps for every 10 percent increase on your dial. The math does not work out to exactly, but it's pretty dadgum close....within a few amps. <br />
<br />
It's how I figure it anyway.

Material looks dirty.........hard to get consistent penetration or metal flow when the weld zone is contaminated

Great info. Thats what I needed. Thanks for everyone's input.
