Hi,
I have grown up fo the last 20 years with my little Sealy mig welder using 0.6mm wire. I recently upgraded to a REAL mig welder - a R-Tech Mig Inv 160.
As my welding is relatively lightweight - 17 deg intersecting 1.25" tubes 2mm thick and 3mm box section I got a 5kg reel of 0.6mm wire as I thought I would have time to "build up" the weld especially in the awkward areas.
As it happens the wire feed speed is so high (about 9/10) with the power setting I use 20 / 300 on a R-Tech Mig Inv 160 that I wonder if I should be using 0.8mm wire instead?
I have tried all sorts of wire speed / voltage / current combinations but these settings give me the best quality weld with full penetration.
So my question is with the heaver wire should I be able to knock the wire speed back so I’m only putting the same amount of metal into the weld and I can still take my time on the awkward welds.
Anyone have any pointers for me?
Cheers, Eric.
