(I hijacked another thread but thought this would be better on its own)
Hello,
We have been replacing an 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. We TIG weld thinner stuff and used this MIG for thicker stuff. It was never pretty - but it worked.
So a lincoln speedtec 405 with PF44 feeder was purchased (poorly informed decision made by management, nothing to do with me), it's not a bad welder TBH - 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 to the Speedtec 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 supplier about Lorch Saprom S3 but I'm wondering if they'll manage to source me a 4m push-pull gun...? One encouraging thing is that Lorch already has a 1050 synergic program.
Of course, this time, we won't be putting money down til we've proven the package works for our application.
Anyone else went through this hassle?
cheers,
Matthew
