SOURCE: Need to know how to

Do you prefer a hobart? This is one reason not to buy one. They are hard to get service for also.I've owned and used extensively several plasma cutters and the best in my opinion is the thermal dynamic 3/8
Its easy on consumables and can sliver stainless to 1/32 . Hobarts are home depot grade. that is probably the best place to find one. good luck

SOURCE: spectrum 2050 plasma cutter will not arc

Possible failure of the trigger switch and or the cable back to the unit. Use an ophmmeter to check that the trigger and cable are good,

Then with the ohmmeter check the continuityu of the cable to the electrodes,

Connectors are always suspect.

These are starting ponts to check.

SOURCE: spectrum 2050 plasma cutter .

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.
