Hello everyone!
I'm having a persistent problem with a Arcmate 100iC / R30iB / Power Wave i400 welding cell and I could use some advice from the forum!
This particular robot cell welds small aluminum parts, each part having four 1" welds. Right after a tip change the welds are beautiful. After about 20-30 parts the operator has to start lowering the trim to keep the arc buzzing smoothly and reduce weld smut / spatter as the arc voltage starts to rise. This occurs in such a predictable fashion I'm thinking about writing a program to check weld feedback voltage and issue a change in trim after each weld.
Has anyone encountered this problem and found a solution to it?
Thanks!
