Home electrical help (welder)

The problem is the wire from the panel to the plug. I am sure if it was wired for a 30 amp, then the wire was sized accordingly. Be sure to check and see what wire was used before you just switch the breaker. If in fact, proper wire was used (and this will depend on distance from panel to plug as well), then just change the breaker. If not, I suggest you run proper wire and make a new circuit.
