Sounds like you didn't specify amperage and your electrician wired it for a 
20a 220v circuit. The plug configuration you describe is a60a on your welder. 
You can go to the panel to see what size breaker is on the wire. My guess is 
you will find a 20a 2 pole breaker in there. Looks like a pair of singles with 
a bar across the handles. You should call the electrician back and show him 
what you intend to use (the welder).

That's a 15A 220v outlet.

That is probably a 30 or 40A plug.  Unless the wiring is sized accordingly,
you cannot just change the receptacle to accomodate the welder.

The outlets are wired with 2 "hots" or phases and one bare ground wire. 
You can NOT use any 110 volt equipment on these circuits.  To use 110v
equipment, there MUST be 2 hots or phase wires, one neutral wire and one
ground wire.

Hope this helps

The pin configuration changes with the amperage rating of the outlet.
NOTE that this does not necessarily relate to the size of the breaker.

I believe (read if I remember correctly) that the - - is a 15A outlet,
the - | is a 20A outlet and the others are heavy-duty (>20A) that vary 
depending on the device. Please assume that the above actual ratings 
are incorrect and ask your electrician (or electrical supplier) which 
is which.

That's a 20 Amp receptical.

That plug type handles thirty to fifty amps.  You find these on electric
clothes dryers and electric stoves - as well as welders.
 
The conductors required for twenty amp circuits, 12 AWG, will not
handle thirty or fifty amp currents, so you need to do more than
change the receptical.
 
Your old house was also more up to date in complying with the current
National Electric Code, in that both a grounded neutral conductor AND
n equipment grounding ( safety ) conductor were supplied to each
box, in addition to the two hot conductors supplying 240V to your
appliance.
