Need help with ac after accumulator replacement

[Warriorpluto]

I replaced the accumulator in my 07 Yukon Denali. I got one from O'Reilly Auto. The Murray brand. After using a vacuum to drain the evacuate the system after replacing the part and charging I put two cans in and it was cold yesterday now today it's not cold anymore. The compressor cycles on and off every five seconds. I tried to put more in but the gauge reads in the red now with compressor on. With the compressor off the low side reads 25lbs but when I try to put more in it doesn't take anymore. Also the hot side line is cold and the accumulator doesn't even attempt to get cold like yesterday.

Was using cheap gauge from Walmart today to get reading. The reading yesterday using my friend REAL ac gauges it was at 45lbs on low side with compressor on.

Pulled the orifice out the other day and it's melted. How could this happen
