I think some welders will do that deliberately to save you holding the trigger down on a long run. Tap once ot start, tap again to stop. Any chance you've nudged a knob to a different setting?

Watching with interest. Ours does the same. I wonder if it is the trigger in the torch that is at fault.

If you end up sending the welder to Tec Arc for repairs, ask how long it will take to repair.
I sent ours in for repair. Took nearly 2 months to come back after a lot of nagging. Not a good company to deal with to be honest.

They’re pretty useless! We had to send one twice for repair as it came back still not working, oh, it was another component on the second visit!!! Apparently they don’t test them, just plug them into their computer, if that says they’re ok they send them out. Oh, would you guess it, it’s stopped working again few weeks ago!

It could be your trigger , it happened on mine. It had got a little corroded and was causing it to not stop. I took hand price apart and sprayed some contact spray on it and aint had anymore trouble.

Mine has a setting on the wire feed unit.
can either be press and hold trigger to weld. Or press once and it starts welding, press again and it stops
I'll try pest pictures of the switch tomorrow

My Hobart works ‘press to start / press to stop’, I really like it and wouldn’t go back

there should be a switch to change between 2 step and 4 step mode. Your currently on 4 step mode you need to change it back to 2 step.

It may be called 2t /4t also if you upload a pic of the front of welder somone might spot it and be able to circle it

I'd be suspecting a faulty switch on the torch. Can you swap for another one to eliminate that?

Assuming that you haven't got the thing set to latch as suggested previously?

Unplug the torch and test the trigger switch. Pull the welder to bits and test the 2t/4t switch. Take the opportunity to blow the circuit boards clean and check for corrosion.
