    Question what # lens is best for Plasma cutting

    what # lens is best for Plasma cutting,I just bought a miller 375 x-treme.

    Smile welcome

    i found using a cheepo engraver to go over my pattern is the best. it wont rub off and is easy to see from any angle. sharpies help also, but a $15 engraver is best for the tricky stuff. heat wont efect it and your glove wont rub it off.
    as for lense state. 5 is recomended, but i use my BWE in the off state all the time. i think that is a shade 3 or 4 . in the off state i'm still 100% protected from UV rays and the shading is just for comfort.
    on S.Steel and some aluminum you can ned a darker shade as its shinyer but for mild steel 3 or 4 is ok. as long as you have ful UV protection the shade is just for your comfort. the 375 is not that big of a cutter so you should be ok at a 5 (O/A shades).
    good luck, keep us posetd and lets see some of your work.here is a little of mine.
    good to have ya with us.

    I've found that a #5 full face shield from Jackson works best for me.

    I also use #5 and mark my lines with a white out pen. Believe it or not the white does not burn away. You can cut right down the edge of the line and the white out stays. I belive its presto brand in the little blue pens.

    FUNFORNOW those POW pieces are great. I cant believe you did them all by hand..Thats awesome. Hey Newbie I asked this question the other day and I found that engraving first is great but also using a cut out of cardboard for the spots you need a steady hand for work real well also. Thanks for your posts..

    I tried with mine but the reflection inside was too much- got a pair of #5 Sunglass style and also use my Optrel in Grind mode- shade 3


    Fine tip White Paint pen.

    It all depends on what I am doing. I have a #5 Jackson Face Shield that I use much of the time, especially when cutting circles in plate. I have also used a Hypertherm/Celstrom Clear Face Shield with the #8 Flip down for plasma cutting. This has worked best when using the plasma for gouging out welds. I have also been lazy and just used my Harbour Freight Auto Dark Welding hood when cutting too. It depends on what I am doing which hood/face shield I grab.

    I haven't done allot of free hand with the plasma torch. I have noticed that soap stone marks get blown off by the air used in the plasma and burns them away as well. I am going to have to try that White Out Pen for myself, that sound like a good idea. I have gotten pretty good with my Miller Circle Cutter Guide and have some good metal straight edges of various lengths that I use. Most of what I cut out needs good straight cuts, no wiggles.

    Wink cover your face.

    i some times use my #5 sun glasses with mine also but i use a clear face shield with it. especially if I'm doing any piercing. all in all i like to keep my face coverd no matter what i use for my eyes.
