Is there a chart that suggests current setting for cutting certain thicknesses of mild steel? I assume it varies based on the torch. How do you know if your current is way too high or low? I have to imagine that too low and it doesn't cut through and too high the consumables will wear out faster?

Uhhh..... I think Mike has a lot on his mind, so file his TIG Chart in your welding file and I will try to help. :laugh:

Keep a couple of things in mind. If you look at the consumables for a particular torch, they are designed to operate at their peak rating. If you start turning down the amperage, SOMETIMES you have to reduce the air flow, as you will reduce the plasma stream. I have found that my Everlast Cut80 works best between 40 and 80 amps. It still cuts great at 20 amps, but I have to turn the air pressure down. If you are using a Ergocut Pilot Arc Torch, you have to maintain the required air pressure for it to function correctly.

With that said, there is a very nice chart on page B-3 of the Lincoln Electric Pro-Cut 80 manual: http://content.lincolnelectric.com//pdfs/products/navigator/im/IM595.pdf

Opps, sorry was rushing and saw chart and thickness and assume welding, not cutting.

Thanks Bret, we are home now. 5AM-7:30PM, long day..

Bret, what is the disadvantage of leaving the plasma cutter at maximum current all the time?

Does the higher current reduce the consumable life?

There are a few things...

1. Look in your manual at the duty cycle. You can't operate it at max for 100% duty.
2. Consumable life will be less at higher current settings.
3. Speed of cut. If you have it maxed out and don't move fast enough, you will end up with dross on the underside of the cut.
4. Power consumption. The more output power, the higher your power bill will be! :jester:
