Welding and Materials

[120mm]

This thing just followed me home.



Dual voltage, automatic adjustments and pretty good reviews from several sources. Doesn't seem like typical Chinese junk. Will give updates as I play with it.

Not speaking without experience, just hoping you'll see the light. Your intent is to build a Cobra replica from scratch. Would you rather drop a $6,000 engine into a chassis built with a $400 mig welder, or a $2500 engine into a chassis built with a $1200 tig welder? Trust me, you'll be SO much happier with tig. And it's easier and less expensive than you'd think. Get on youtube,

A good weld with a $100. 00 mig would be better than a bad weld with a $5000.00 name brand tig no matter how much the motor cost.

I wouldn't touch a TIG with a ten foot pole.

I've built several aircraft with oxy-acetylene and like sound, properly soft welds, thank you. Plus, O/A alloy is easier to work. TIG creates too much of a HAZ for my taste. It's possible to get roughly ok welds with TIG, but you need an o/a torch to normalize afterwards, so what's the point? TIG is an answer to a question not asked, imo.

The MIG is for learning and building fixtures. I might try it on the 3" pieces, but the rest of it will be O/A.
