yes, they are at the sub panel, wire size is # 4 ACSR. pls help me solve this problem. Thank you
 
How long is the run from the main panel to the subpanel?

What is the breaker feeding the subpanel rated at?

How much current is the welder rated to draw?

Sounds a lot like an undersized feeder to me.
