Does it have a gas valve in the torch or is it a solenoid inside the machine?
Easy test, does gas flow if you press the trigger with the machine turned off?
If it does then it's in the torch and is probably just a bit sticky, a little bit of WD40 applied carefully should free it.

Hi
We've got a snap-on version of the 130 (similar) which does the same every now and again. I found that the valve in the handle keeps sticking and a quick strip , clean and lube usually sorts it. A 10 min. job.The other thing it could be is the spring may have gome , not pushing the plunger down , but you'll need to strip it to check anyway.

Cebora 180 usually has electrical gas solenoid valve to control the gas, so do this to decide whether it's a sticky solenoid or a faulty pcb - Switch machine and gas on, pull trigger so gas flows. Release trigger and if gas is still flowing, turn the set off at the mains plug (not the machine). If gas still flows, it's a sticky solenoid, if gas stops, it's the pcb.
The reason for turning the machine off at the mains is that sometimes turning off at the set gives enough of a jolt to release a sticky valve, so avoid knocking the set whilst testing.
Some types of solenoid valves can be carefully stripped, cleaned and will work for ages but be aware that the removeable part of the valve body is sealed with pipe sealant and can be tough to unscrew without twisting the delicate body tube and ruining the valve. Solenoids are quite cheap but get the right voltage - it's marked on the coil body.
For gas valve in handle types, Wozzaah is spot on.
