Sand Blaster: air shot out of water trap.
1. do you have an adequate air compressor, meaning can deliver sufficient air supply to the sand blaster. 2. if you have an air leak at the water trap at the bottom of the trap it self. you need a new one. 3. it is a must to have a water trap when using a sand blaster.
So what I would do is replace the water trap and install the new water trap at the compressor between the compressor and the air hose coupling. the reason for this is your less likely to have it fail at the compressor VS at the sand blaster. once you have done that. you need to make sure that you have no more than 3/4 of media / sand in the sand blaster itself.
then open air supply valve #1 where the water trap is or was a 1/4 -1/2 way. then open the mid way valve#2 1/4 - 3/4 way. and the bottom valve#3 open 1/4 - 3/4 way. getting the air supply valves all set correctly is hard to do some times.
Air valve #1 supplys the air to the blaster.( more air the better)
Air valve #2 supplys the air going into the top of the blaster tank. ( wich pressurizes the top of the tank to push the sand or media downward )
Air valve #3 supplys the air mixture to sand at the bottom of the tank.

Instruction manual for use
If you have the user's manual there is some rudimentary information there. If you have a local welding supply company, their catalog may contain general information.
The short of it is you will need to develop a feel for your machine. When you start with scrap of the same size as what you will be welding on, select your heat setting for the matel thickness, and strike an arc- nothing fancy all you are going to do is adjust your wire feed rate until the weld sounds like fring bacon only as quiet as you can make it.
once you have that setting run a bead on a corner weld or a **** weld and look at the back side- if it the weld achieved full ***********, and looks like the top side- you have it set right. Ideally the weld pool will only be twice in width as the thickness of the metal to be welded in most situations. Neithert undercut nor excessively proud of the surface.
if you have the model number and make, find the homepage of the manufacturer (except Century) and download their user manual for that make and model of yours.

My CLICK Multi Functional Rechargeable
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.
