Hello, sorry to drag up an old thread, but it seemed relevant since you were all talking about 1050 wire...
we have been replacing our ANCIENT ESAB step mig with push pull gun, it was beyond economical repair. But one thing this used to do was run 1050 aluminium for our ducting and fans - we use pure aluminium for it's resistance against acid gas in our process plant.
So a lincoln speedtec 405 was purchased, even without pulse it runs Mg and Si alum really nicely, BUT it can't feed 1050 wire to save its life. With the best and most sympathetic setup possible on a 3m gun, it birdsnests every 2 runs, whether cold or hot.
So we bought a Binzel push-pull on the advice of LWS, they fitted it with a specific lincoln power connection, sync'd up etc... but it's an 8m gun (standard) and it doesn't have the power to pull the wire properly. So it ends up pushing more than pulling... and birdsnest city. (it's a PP36 and they have finally admitted it's not fit for the job)
We need a powerful 4m push pull gun, but the LWS is struggling to find once since all the major manufacturers make 8m ones as standard. They called Lincoln UK and they weren't interested.
for info, we are running 1050 1.2mm wire at around 240amps and 26volts on some large fillets stepping between 20mm hubs and 10mm blades. It's probably on the limit of a Binzel 36 aircooled gun, but the duty cycle is quite low. (it never runs for long enough before it mis-feeds!)
Does anyone have any experience of running this wire like this? I'm at my wit's end, the fab guys are refusing to do the job because it's such a soul destroying job of clearing a birdsnest every 2 minutes.
I've been given the go-ahead to buy a new welding package outright, been talking to a WS about Lorch Saprom but I'm wondering if they'll manage to source me a 4m push-pull gun...?
Of course, this time, we won't be putting money down til we've proven the package works for our application.

Hi Paul, sorry if this has already been said as I know it’s old post now, haven’t been in here for a while.I had a blast at MIG welding aluminum for the first time today - first photo - not too bad apart from an end crater - 3 runs there.
Messing about with AlSi and AlMg wires - AlMg gave us the best welds, but with no problems with feed etc, which i'd expected. Combination liner, oversize tips, U rollers and an expensive welding set seems to have sorted that
2nd/3rd picture - the parent material cracked right through at the edge of the HAZ. Why does it do this?
