 It's a good idea to know the basics before you start welding (see the people above), but here's some general tips:
-- Make sure the welder is set to TIG, not MMA when you start welding

-- Wear long-sleeved clothes when welding, otherwise you might get an unpleasant sunburn. There's lab coats in the workshop you can use.

-- Don't weld galvanized steel (blacha ocynkowana)! The fumes are *very* toxic and it's difficult to weld too.
+  * Don't weld galvanized steel (blacha ocynkowana)! The fumes are toxic and doesn't produce good welds. If you really need to you can file the zinc coating off. Leave at least 1cm between the weld and any of the coating.
-- 90 Amps is a good starting setting for welding - if you don't know what current you need for your project, you can start with that and adjust based on results.
+  * If the weld comes out dirty and splattery, make sure the valve for the argon gas cylinder is open. The regulator should show about 6 l/min when the torch "trigger" is pressed
-- As a rule of thumb, the electrode should be sticking out from the ceramic cup by about half of the diameter of the cup's opening.

+  * While welding, keep the electrode as close to the material as you can without dipping it into the puddle. 3mm distance is alright.
+  * If you just finished welding a part it might still be very hot even if it's not glowing anymore. If you touch it with your bare hand you might burn yourself
