Hi,
At work we use pulse migs to weld aluminium, the machines are around 4 years old and have all the bells and whistles. twin pulse etc. We use 5356 1.2 diameter wire. The welds we produce must be leak free as they are then tested and any leaks etc need to be repaired, so thats why I want to set the welder up to work it's best.
I've been through the menu system to configure the welder and there are various things that i'm not sure what they do and some that I know what they are but not sure what values to use.
I've played around with twin pulse on it, but I believe it doesnt suit our application. It's only meant for thin material or gaps I heard?
Gas pre-flow - I currently have this on 0.5 seconds
Gas post-flow - I think this one is on about 1.5
Start Current - I've got this on 20 %, I know it bumps the amps up for the start of the weld. What should this value be set at?
Crater fill current + Crater fill time - Have no idea about this.
Wire burnback time - not sure
Arc length Correction - again not sure what it does.
Arc length Control - There is a selection for voltage or wire and its currently set on wire.
Any help would be good
Thanks
