I've chinese plasma cutting machine. I'm new to plasma cutting. I've a question how to decide that i should use air cooled tip or water cooled plasma tip ?
I should use water filled up in my table 'pictures attached ' or my table should be dry ?
I tried to cut 3mm mild steel at 45 amps and 3000mm per minute and it damaged my table grill .
I'm really confused.

My plasma torches were always air cooled. Water cooled sounds like a good idea, maybe complicated tho. The grill under the sheet is expendable, expect to replace the slats occasionally.

Why this blue pipe is here ?

While cutting 8mm mild steelsheet with plasma, cut is at angle of 45 degree from 2 sides while other 2 sides are at 90 degree. How i should make 45 degree to 90. Current is 100 amps and speed is 500mm/min.
