Magnetic reed switch near output is probably bad. Look for coil behind front panel, there is a small glass tube inside, with 2 small wires.

Arc welding is any welding process that uses electricity, which includes MIG, TIG, and SMAW. SMAW Shielded metal arc welding is most commonly referred to as stick arc welding. In SMAW welding the stick electrode contains a flux that keeps the atmosphere from contacting and contaminating molten metal. It is a good choice for welding thicker metals. It is a manual process, that is hard to get a hand of. yet once done. MIG welding is a semi-automated process that is a much better option to use on thinner metals. It is easier to get hang of than SMAW welding. A welding MIG wire is used in the MIG welding process. TIG welding is the hardest as compared to SMAW & MIG welding. It is capable of producing an autogenis weld which is one does not use any filler. These are some differences in arc welding processes.

Not enough Continuous Amps. Contact Lincoln direct. https://www.google.com/search?q=Lincoln+225+welder ..

Contact Marquette directly to request the manual.

It could be the circuit that supplies the current that closes the contactor. You need to check the switching circuit with an ohm meter, the contactor coil with the ohm meter and finally the voltage on the contactor coil..

Sounds like control board is bad. Call manufacturer to confirm. Good luck.

\I have a couple of sites that may help you. Free User Manuals and Owners Guides ManualsOnline com ManualsLib Makes it easy to find manuals online

what are you welding ---what are you using mig--tig--stick etc --are settings right =is the project clean

normal the light emitted from a tig arc is many more times intense that normal arc light so you will need much darker lens to view the welding process through if you are using automatic darkening lens thenhave it checked that it is suitable for tig welding as the dark settings may not be low enough or adjust the settings on the helment to lowest possible

voltage control failure have a technician test to find the fault

Check your ground

first place to check is a properly grounded and connected ground wire to complete the weld circuit next is to check the relay that energizes the weld circuit when the trigger is pulled check for fuse blown take it in for a proper diagnosis and fix

The transformer may have failed or the voltage control rheostat or both.

Not sure what machine you have, but it should be DC straight (electrode negative or DCEN) and DC reverse (electrode positive or DCEP). The polarities have different characteristics. For example, if you're planning to TIG weld, you would either use DCEN or AC (if welding aluminum). For the general stick welding process, DCEP tends to give you a deeper weld. The welding rod you buy will have recommended machine polarity and amperage range settings, you should use the recommended polarity for whichever rod you're using because different rods are designed to weld under different circumstances. But, generally speaking, most welding rods for steel will work on DCEP without much trouble.

I think you mean you have a Miller Synchrowave 200.

Typically, you would want to use AC below about 250 amps. In this case (to keep it simple), use AC, adjust your balance to about 4, use an 1/8" pure tungsten, pure argon at about 20CFh, and set the panel at 170amps to get things started. For general purpose, use 4043 filler.

Now - these are just generic settings, but they will get you going.

#1: Atom arc rod is very good and expensive rod comparatively speaking. 8018 is similar to 7018. It is an all position rod but instead of 70,000 pound tensile strength , it has 80,000 pound tensile strength.7018 is commonly used in repairs or steel construction 8018 is used in appilcations where the need for a higher strength or stronger weld is called for . Usually when welding higher grade steel than A.-36 It can be used in place of 7018. 5/32 calls for 150+ amps. 1/8 is a more common size.Remember Atom arc is top of line but finding someone who will pay the difference or needs this rod may be hard to find.

Check for any loosened terminals and observe the welding machine if it sounds like hamming when connected to the power source. If you hear no sound, it means that no power is coming in. Check your fuse or breaker of the welding machine it might be busted already.
