Welding Tips and Tricks

Hello my name is Matt and I am looking for advice...I am about to begin manufacturing small Radio control frames our of aluminum and steel.

They will be assembled out of 1/4" aluminum tube and 1/4" aluminum rod fish mouthed for joining together mounted in a jig for welding. Same will go for frames made of steel.

My question is because these welds are tiny what type of machine would I need to join these connection points.

Currently I am looking at this unit AlphaTIG 200X

Any advice would be greatly appreciated
Thank you,

Matt

Hey mate. It's not the capacity you need to worry about, as that material won't need much heat. Its arc characteristics to be able to pin point the arc. Not sure how good lower end machines are at this, no matter what they promise. That's said, you can never really get a "tiny" weld on alum. Just the nature of the beast.

I have the machine you are looking at. Very impressive machine for the money. If you can post up a pic showing what you are actually trying to weld, I would be happy to try welding something similar and let you know how it does. I've been demoing this machine for a while over at Welding Web.
I have an RC rock crawler that I need to build a frame out of aluminum for at some point
