Super cut 50 plasma cutter

[performance]

For the larger plasmas, we have wheel guides like the one pictured.

Rink,

Generally, No more than a shade 7 us required for plasma cutting. I recommend a 5 unless its over 60 amps. The arc is not usually as visible and partially obstructed so a darker lens is not required.

With that said, I use a pair of Nemesis cutting glasses instead of the cutting shield or welding helmet. Its adequate and freeing.

Thanks for your response. I went over to the Central Welding Supply site.
Here's what they recommend for plasma:
Current Level
in Amps Minimum Shade Number

Below 20 #4

20-40 #5

40-60 #6

60-80 #8

I'm still looking for a clever way to protect my eyes and see my drawn
lines for the cut.
Thanks again.

Try yellow or bright white lines with very little back ground light.

Wayne is right.

I use a Markal paint ball valve action marker. Yellow or white shows up very well. Soap stone is not good for this. A marker will last a long time, not as long as a piece of soap stone and its much pricier, but the marker won't break into pieces the first time it hits the floor either.

On one of the welding supply stores I saw a marking pen that was said to not burn away like soap stone or the other markers. Wish I had link but have been wanting to try one. I also found that a sharp awl dawn down your line to work fairly well, at least better then soap stone. Of course the awl works better on slightly rusted or steel with mill scale.

The Markal has this type pen.
