Check your torch. It sounds like the consumables are bad. Good luck.

It sounds like a control board. Call Miller Electric and they will be able to help you pin down the problem. Good luck.

A plasma stream is created when an electric arc is introduced to a gas passing through a restricted orifice under pressure ionisig the gas. The plasma stream can be controlled to carry out welding or cutting operations.

The other difference between gas/gasless is the ability to reverse the gun polarity which you can't do with a gasless only welder. You can get it to work but not safely and reliability could be an issue also.

Is free gas between the outlet of the regulator and the welder itself?

I bought 2 more torches after finding how good the first one was. One failed after a few months, but I had no trouble getting a refund from Bunnings when they couldn't replace it - after all, they are legally obliged to replace or refund if it fails under 1 year old. Today the second one failed, so it wasn't just bad luck! I took the advice of criss994 and opened it up (you need a special screwdriver) - sure enough, the fuse had blown. Soldering a physically larger one in (M205 - 20mm long by 5mm diameter - I didn't have the 10mm x 3.6mm replacement) was fiddley but there is enough room. The original fuse is a fast-blow 1-amp rated one - so perhaps the induction coil feeding the torch causes a surge, as the unit is rated at only 1/100th of an amp. My replacement is a slow-blow 630mA fuse - it should overcome any surge problem.

If you are smelling, then the engine is probably flooded. Pull the spark plug out and dry it off. Crank the engine over a couple of times with the plug out. Make sure the fuel is fresh. Reassemble and try again. Without the choke. If it does not start, use a little starting fluid.

Faulty earth make sure the cable and clamp are making good contact at the workpiece.

you need to add oxygen flow to the acetylene flow! something is blocking the additional air/oxygen flow, check it! [if what i've guessed is you having an acetylene torch you want to get running]
