help with arching
You probably have loose connections (loose screws) in there.
Turn off the main breaker and then tighten up all the little screws and set screws. Firmly but not with tremendous might and strength.
With its handle turned off, unsnap and replace each breaker. This motion helps clean the connection underneath it which will improve the electrical contact. If a breaker is loose you should leave it off until and unless you can relocate it to a different slot where it fits reasonably tightly.
Save for an electrician the big screws where the fat wires come in from the meter. But get these tightened up very quickly particularly if arcing happened on them or they got warm.
Loose wires will heat up and the insulation can melt and also the terminal or terminal strip can become deformed and damaged. In extreme cases you would have to replace the entire panel.
The disadvantages of crab apple trees. In summer, the apples are too sour to pick and eat. In winter the birds come and leave dropping all over the place.
