We are in the business of Selling Esab make Welding Machines. We come across a lot of customers who want to do Aluminium MIG welding but face a lot of problems. There are some suggestions:
1. Aluminium is a soft metal. Therefore the feed roller should be U groove or Knurled so that it grips the wire tightly and does not crush it.
2. Replace Steel liner with Teflon liner. Teflon liner will ensure smooth wire feeding.
3. Contact tip should preferablely Copper Chromium Zirconium and of short length as compared to steel welding.
