Hey,
I have been running Si bronze with pulse MIG for a while now and getting good results. I need to do some Al Bronze and just order a roll but could only get it in 1.2mm where as I had been running 0.9mm Si Bronze.
I have a CIGWELD xf252 with a pulsemate that recommends pure argon for 0.9mm SI bronze and a C10 mix for 1.2mm Si Br. I have only ever run SI/AL bronze with pure argon (both MIG and TIG) but as my welder is recommending C10 for the larger wire, does anyone have any experience running a CO2 mix for MIG bronzes?
The manual is recommending C10 for the 1.2mm wire for both normal MIG and pulse. I have pure argon and helium as well as argosheild universal. I also have about 1/4 of a small bottle of C10 I can use for testing to. If I end up needing a mixed gas I would prefer to stick to the Argoshield as I pay about 50% less for a 10m3 bottle of Argosheild vs a 2m3 bottle of C10. I can mix the argoshield down with the argon to get it to about C10 but as I have no experience with bronze and mixed gas, does anyone know if the O2 in the Argosheild is likely to cause any issues?
I do find that there is some soot build up with pure argon already so I would expect that to be the same or more with a mixed gas. With the pure argon I find that the bronze flows pretty well, I would assume it would be even more fluid with the CO2 addition.
I will test with both gases later this week when the Al Br gets in but in the mean time I would be grateful for any input if anyone has any experience with running a mixed gas with MIG brazing. I'll post results if it's of interest to others.
I've added links to the machine and pulsemate manuals if its of any interest below.
