SOURCE: how hard is it to change out the main circuit

The replacement of a board is no TOO hard, just DRAW a Diagram of ALL connections when you take the "Old" one out. NEVER work on the machine live Duh, also always wait a bit to allow capacitors to discharge, or use a shorting stick, if in a hurry. Anyhow, make sure you keep all fixtures together note down all connections and label them with little stickers, With any other information on the stickers as need be. I always do this as one never remembers whats what after a bit, anyway. Just be methodical, and you will prevail.

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: can i plug my miller spectrum 1000 plasma cutter

no you idiot! the plug is different & even if you could somehow, its half the power output. Your plasma welders for the matter, have whats called a duty cycle, which plays into effect.... electrical load level....ect.
HOWEVER-- you can plg ito the same outlet as your stove, washer & dryer plugs. DON'T BURN YOUR HOUSE DOWN, The wife will kill you!

Spectrum thunder plasma cutter will not cut steady, keeps stopping and have to pull trigger to cut


Check the contactor contacts for pitting. if severly pitted, replace contactor. If a death grip on the switch makes it work better then a light touch- replace the trigger switch.

Miller 375 x-treme fires about 30 seconds then stops it doesn't stay running, no trouble lights...


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.

When you start cutting it will cut about 2 inches and kick out you let off the trigger and pull it back on it will do the same as long as you do that it will not cut continusle please advise does not...


You may need a better air supply. Also check the tip. This sometimes happens with mine when the tip gets pitted, not sure why but changing the tip sorts it out. They are fussy machines in some ways. Dont like dirty material, need a good earth.

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.

Plasma cutter no cutting


the tech is probably pretty close to the cost of board,but you may have moisture in air that still wont take out the p.c..you have a warrenty on the unit,go to your local welding store and request a new one if refussed tell them you want to talk to the miller salesman which they should have no problem to set up.if not call miller direct in appleton wisc.they are good people.

Miller Spectrum 375 problem


It sounds like you have a problem in the power supply input area. Make sure your voltage select switch is in the correct location. Unplug the unit and switch back and forth between the two positions to clean the contacts. Try again. If still bad check you terminal lug connections on the input lead wires. If still bad please answer these questions.

Does the power indicator come on at all? Does the fan start?

Pull the trigger ,air comes out no fire


Ck the ground and the condition of the tip. The more it gets concave the harder it gets to get a arch. Gun angle is also important, hold at right angle to work and don't forget a very good ground.
