It’s not normal that the welding gas tank you think should still have gas is now suddenly empty. So if this has happened to you, then you have some mig welder gas problems going on that you must sort out. However, if you look at the tank and all the connecting hoses seem to be fitting well, then you have to do some adjustments and tests to find out the real problem.
Basically, one of the most common welder problems in terms of gas tanks unusually going empty for no reason is due to mig welder gas leaks. Regardless if you’re using argon, helium, CO2, or any type of shielding gas, these are gases that can pass through even to the tiniest hole or loose-fitting. Unlike flux core welding which doesn’t need gas, MIG or TIG welding requires gases that you must watch about.
In this video, I’m going to show you how to find mig welder gas leaks through very simple means and all you need is soapy water and of course the use of your senses: sight, smell, and hearing. When mig welder gas problems occur, you need to fix them fast so you don't spend money on shielding gas without actually using it.
For a quick summary of resolving mig welder gas leaks, I’m also showing you here how to fix the leaks by adjusting the flow meter that is connected to the gas tank. The use of soapy water is to find the leaks that will create bubbles once air passes through some gaps or holes. I have also shown here where to find all the possible leak points right from the gas tank to the rear of the welding machine and to the switch inside the machine that turns the gas on and off.
Also, One of the common welder problems where a leak can happen is also with the euro fitting where the gas passes through when you press the trigger of your gun. To check out leaks, you only need to disconnect the euro fitting, and see if the very small o ring is still in place. So watch the video and see how this small part is able to leak gas unnecessarily without you knowing it.
On the other hand, if you’re into flux core welding, you won’t experience any leak problems because this type of welding is gasless. Yet, there could also be other issues that might happen with flux core welding and we have another video for that see below.
