20 Most Recent ARC Auto Darkening Lens Welding Helmet Arc Mig Tig Welder F Questions & Answers

helmet need batt.
solar power only works with batteries

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.

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.

wityh what little imfo you gave I would first go to the main contactor ,turn unit on pull gun trigger see if the contactor pulls in.that is where primary power comes from to create arc.

$159 sounds like a "throw away" machine lasting for about 6months, usualy fails after the guarantee runs out, save up for a good set that will last, as for larger machine, when you buy a system you need to look ahead, you may want to start making gates and railings or bigger so you would be looking for a system of around 200-250amp with a continous output of 180190amps. check the data plate on the power scourse under 60%
