Spectrum 2050 plasma cutter will not arc

Have you watched to see if the pressure light comes on right before shutdown? If so you may need to add a tank right next to the torch base to address the pressure drop assuming your air source is able to deliver adequate volume to the cutter continuously and you currently have more than 25 feet of hose between cutter and compressor. It might not hurt to check the internal filter as well.

Is the compressed air pressure in the limits for the unit to work. try turning the pressure up.

Check compressed air pressure is in limits otherwise unit will cut out. Try adjusting the pressure up. also make sure the supply pressure is correct as it may not be your plasma cutter at fault.

depend the circuit boar but is be twin 500 and 700 usd

go to miller.com they have downloads for most everything they make. it sounds like you might have a ground problem or a bad connection in the tip

do you have right air pressure.

This is relative to 3 causes , contol board , pwm board or torch

check groun dconnection on workpiece and where connected to machine>> check reset switch.>
There is a screw in fuse on the back make shure you unplug the machine befor removing any fuse or working on any electrical problem.>>OUCH!

in order to cut the thicker steel just boost the air pressure this will allow you to thourghly blow through the steel. just remember not to turn it up too much. this should do the trick. please rate

Depending upon the design of the torch (e.g., orifice diameter), electrode design, gas type and velocities, and the current levels, several variations of the plasma process are achievable, including: * Plasma Arc Welding (PAW) * Plasma Arc Cutting (PAC) * Plasma Arc Gouging * Plasma Arc Surfacing * Plasma Arc Spraying
