If your Miller Trailblazer 302 AC/DC welder generator is starting and putting out electricity, but will not weld in any position, there are a few things you can check to troubleshoot the issue:
Firstly, check the welding cable connections and make sure they are secure and clean. Check the cable itself and make sure there is no damage or corrosion.
Secondly, check the welder's ground clamp. Make sure it's clean and tight, and that the ground connection is secure.
Thirdly, check the welding gun liner, and make sure it's not blocked or damaged, this can cause the wire to feed improperly.
Fourthly, check the wire feeder, make sure it's functioning properly, and that the wire is feeding smoothly.
Lastly, check the voltage and amperage of the welder. Make sure it's set to the correct settings for the type of welding you are trying to do.
It's important to check the manual of the welder for troubleshooting steps and also check the warranty of the welder and see if it's still covered by the manufacturer. If you are not able to find the problem or if you are not familiar with welding equipment, it's best to take your welder to a qualified Miller Electric welder repair service center, they will be able to diagnose and fix the issue.
A fast idle problem on a Miller Trailblazer 275 DC welder generator can prevent the machine from recognizing an arc and starting the welding process. Here are a few things you can try to fix the problem:
Check the fast idle control and make sure it's not stuck in the off position. If it is, try moving it to the on position and see if the welder recognizes the arc.
Check the fast idle solenoid and make sure it's not damaged or corroded. Clean it with a contact cleaner if needed, or replace it if it is damaged.
Check the wiring going to the fast idle solenoid and make sure there are no loose or corroded connections.
Check the Engine RPM, it should be around 2000 RPM, if not, check the governor and carburetor settings.
Check the fast idle switch, it could be stuck or damaged,

There could be a few different reasons why the welder on the Miller Trailblazer 250G 4000 watt generator welder would quit working but the generator still works. Here are a few things to check:
Check the welding settings, make sure they are appropriate for the type of welding you are doing. Make sure the voltage and amperage are set correctly.
Check the ground connection, make sure it's clean and tight. The ground connection must be secure for stable welding.
Inspect the welding cables and make sure they are in good condition and that the connections are tight.
Check the welding gun and make sure it's clean and in good condition.
Check the main contactor and make sure it's engaging and disconnecting properly.
Check the main circuit breaker and make sure it's not tripped.
Check the power output of the generator and make sure it's within the correct range.
Check the control circuit and make sure that it's not damaged or malfunctioning.
Check the engine oil level and make sure it's not too low, low oil level can cause the engine to overheat and stop working.
Check the air filter and make sure it's not clogged, if the air filter is dirty, it will cause the engine to run hot.

The oil is used as a cooling system, therefore if you ran a machinery without expect to overheat, dismantle your welder and check which parts have melted, repare or replace them and make sure there is enough oil at all time
Lincoln's welders have a very weak on/off switch sometimes you need to wiggle the switch a little bit to help make contact. Try this, open the welders cover and using an insulated tool and insulated gloves try to bridge the switch. If the machine makes contact then buy a new on/off switch and change it.Other tip is to check your cable plug to see if all cables are still in place.
Check for output voltage (ac or DC depending on model).No voltage,welder has a problem.
You must have a clean ground clamp attached to bare metal with some welders to make them work.
