OK. That makes sense. So a collet or two, cups (most used size...6 & 8 ? ), collet body, and maybe an insulator and tall cap to keep as back up. Sound about right? I assume that you are relatively new to welding. Get more collets, at least 5, maybe even 10. At the beginning you will be sharpeni...

When I'm feeling too lazy to walk over to the bottle (often), I "verify" that the gas is where I need it by holding the torch up to my tongue. Turns out my tongue has a decent calibration. Not joking. :lol: I've tried that as well :lol: :lol: But instead of pressing the gas test button, I...

Using a gas lens below a #6 cup is essentially ineffective at reducing the turbulence. So mostly collet bodies should be used with <#6 cups and experience tells me that a collet body does not react well with 2x cup size gas flow. In fact, welding with #5 on inside corner joints, I use less than 7cf...

I'm with Buggy... turn the knob until the weld tells you what it wants. There is no mathematical formula that can dictate conditions accurately enough to determine flow requirements. Differing ambient temperature, cylinder pressures, regulator quality, joint configuration, etc.. all play an integra...

A fun math exercise I'm sure but for the most part I let the weld tell me with the flow should be. (I'm far away from USA, but I wish that one day I'll get there :D ). You may have waited too long. The USA as we knew it doesn't exist anymore. Speaking of which... how's the weather over there in Mac...

The calculations are fine, but un-necessary to a certain extent, due to the fact that you decided to use 0.06 as a constant in the calculations. Since area can be shown to be proportional to diameter², the round-off errors of actually calculating the area using π can be eliminated entirely. Since y...

For stainless I run my #10s at right about 20CFH. They have a diffuser screen which I think helps out a bit. I'll run the #12s about 25CFH. Both get bumped up a bit when I need more stickout. Works well enough for me. I also use x2.2 for the "rule of thumb" you had mentioned. That gets it...

Since I started welding, it was never logical to me the way gas flow was set for TIG welding. I was hearing the popular rule "Cup size x2 = required gas flow rate in CFh". For example 5 cup = 10 CFh; 6 cup = 12 CFh; 7 cup = 14 CFh; etc. The diameter of cup 5 is half of the diameter of cup ...

It will work as long you use direct current straight polarity (DCEN). But I'm not sure where are you going to find tig torch with mig euro connector. You can "adapt" the mig cable to screw a tig torch on it with some brass fittings, but the cable will be extremely heavy and stiff for tig w...

Hello everybody. I'm 24 years old mechanical engineer (I'm planning to start master studies this year). I'm young GTAW welder, but I am also capable of welding GMAW, and SMAW. My gear is: -TIG 210 AC/DC, modern inverter with all the bells and whistles; -MIG 250, industrial transformer with pulse and...
