Hi there,
I have just bought a 180 turbo MIG, secondhand, c/w a gas bottle. I used to use a 130 mig (.6 wire) which i have had for years repairing and improving my stock car. I found the 130 with the small sealey gas bottles (CO2/Argon mix) ok, but real penitration on 3mm steel was quite a challenge, the welds were strong and did the job.
Since i have started using the 180 turbo (.8 wire), i have found the welding much better, and a lot easier, again i use an Argon mix with more gas pressure than before. Now my Question:
"What is the cause of brittle welds?"
I find the welds which look great, (neat and symetrical) don't seem to have penitrated and break off after impact, the metal is clean and again 3mm. The weld process sounds fine and pool control is good for a non professional.
Thanks
