When the welder is first turned on I can weld with gas for about 5 seconds. Then the breaker trips. ( i have the proper wiring and breaker). The more times I reset the breaker the shorter the weld time before the breaker trips again. The breaker only trips when I pull an arc. It does not trip the breaker when I pull the trigger, only when I strike an arc. It does not trip when I just turn on the unit. This problem has been getting worse for the last several months. Again all this happens when I run the gas. When I change the polarity to use NO gas, the welder works just fine and the breaker does not trip. I'm stumped. Any suggesstions. The clarke 130 is approx 4 years old.

I hate gasless MIG welding. Bought the flux wire and could not get it to weld. Kept running the current up to stop cold welds and tripped the breaker. It welds very good with gas though, so it's not the welder.

I assume you removed the broken wire and reloaded correctly. So if the power is now reduced I believe the power supply is not running on 220v. This can be from one leg of the breaker being tripped. Check your wiring starting at the main panel circuit breaker, then the receptacle, extension cord, welder circuit overload protector (on back of welder), and then inside at the main transformer. See if you see any burnt wires at the transformer or apparent heat damage on the windings.

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:

1. 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.
2. Check the ground connection, make sure it's clean and tight. The ground connection must be secure for stable welding.
3. Inspect the welding cables and make sure they are in good condition and that the connections are tight.
4. Check the welding gun and make sure it's clean and in good condition.
5. Check the main contactor and make sure it's engaging and disconnecting properly.
6. Check the main circuit breaker and make sure it's not tripped.
7. Check the power output of the generator and make sure it's within the correct range.
8. Check the control circuit and make sure that it's not damaged or malfunctioning.
9. 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.
10. 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.

It's important to check the manual of the welder for troubleshoot 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.

Would you write back and clarify what steps you have taken to narrow down your search? I'd like to know if the breaker is weak and needs to be replaced. Have you plugged your welder into another receptacle to see if it trips that breaker? I don't think the trigger has to do with this problem. The symptom is that as soon as you turn the welder on, it then trips the breaker. So this tells me that the electrical cord is not shorted. When the breaker trips, is there any delay or is it instant? If there is a delay, does it sound like it does while you are welding? Do you hear that "Transformer, buzzing noise"? The trigger activates the feed motor, that alone isn't enough to trip this breaker. Which make and size welder do you have? I really am dependent on detailed information, you are my eyes and ears. Please write back with any questions or new details and I'll do my best to help, good luck.

I am having the same exact problem on an old Hobart Beta Mig 200
sometimes i can weld for 5 minutes and other times as soon as I hit the trigger it trips the 50amp breaker. Any help?

Is enough for this machine, but probably is not a fuse dedicate it just for this end side.
If you can turn all lights off and other items that might be in use with the fuse. If you can't then upgrade the fuse to a 30amp.

Rated Output at 20% Duty Cycle 150 A at 16 VAC
150 A at 16 VDC Welding Amperage Ranges AC/DC 10 - 165A Max. Open-Circuit Voltage 80 V Amps Input at Rated Output AC-230V: 21A
DC-230V: 23A You need to configure the machine to specifications of the material you going to weld.That is :
-The material of the job
-And the proper amperage to use for the material.
-For aluminum you will use A/C
-Stainless Steele / Chrome Molly D/C

Aluminum MIG Welding
1. The best feeding of wire for aluminum is done with a spool gun. If you can't use a spool gun, use the shortest gun possible and keep the gun as straight as possible. Use Argon only for shielding gas. Only use a push gun technique when welding aluminum. 2. If you are having feeding problems, one thing you can try is a contact tip that is one size bigger than your wire. 3. The most common wire type is ER4043 for all-purpose work. ER5356 is a stiffer wire (easier to feed), and is used when more rigid, higher-strength weld properties are needed. 4. Clean the aluminum before welding, to remove the oxide layer. Use a stainless steel wire brush used only for cleaning aluminum. 5. Fill the crater at the end of the weld to avoid a crack. One way to do this is to dwell in the weld pool for a second at the end of the weld.

Try replacing the circuit breaker. They can/do get weak and tend to trip before they actually reach the rated limit.

If it is new i would not play around with the welder Just take it back to where you bought it get them to replace it under warranty

If you use it regularly, the liner should be replaced about every 6 months. Make sure you get a wiper for the wire. It goes inside the machine, on the wire, just before the feed rollers. It keeps the dust from clogging the liner.
