Horror Freight Titanium Mig 140---Seek Honest Assessment from the Pro's

Need a lot of amps to weld aluminum.
I dont weld aluminum so i cant give specifics. 140 is a fair size for a 110v welder and if you weld heavier steel you will run into problems. Preheating helps on thicker steel.
i did an awful lot of welding with a 100 amp 110 volt (heavy on the awful)
I have since upgraded a couple times in 30 years,last welder was $2700.
Mig,tig and arc in one machine.

not knocking hf welding machines, and if you are new to aluminum welding, i strongly suggest you perhaps consider taking a welding class. at the very least find someone to give you some hands on lessons.
