Arc Mate - Adjusting weld trim programmatically?

    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!

    I was hoping you were going to say barrel instead of spool. I've had similar issues with barrels of wire and Tregaskiss contact tips where I needed to use their ".045R" contact tip for .045" diameter wire which is a 1.0mm diameter tip instead of 1.2mm.

    The easiest thing I would try it to use the .045" diameter tip instead of the 3/64". The reason I needed to use a slightly undersized contact tip on a barrel of wire is because the cast and helix of the wire didn't provide as good of contact for the wire in the contact tip.

    I would also check and verify that you have a good connection of your weld cables to the wire feeder and the fixture, and that they are sized appropriately for the amperage you are running.
