I mainly looking for a welder for bike frames and maybe a couple of projects around the house. Looks really simple to use.

That is the same model I have. Yes, it works straight out of the box.

A few hints:

1. The torch head is made by Binzel, so those are the "consumables" you will need for replacements. The HF contact tips don't last very long, so go to your nearest welding supply house and buy a few .030 and .035 tips.

2. The handheld welding mask will work for a while, until you can get a self darkening helmet. Do NOT purchase that from HF. Theirs are too slow to darken when you strike an arc, risking burning your eyes.

3. Buy your welding wire from the welding supply house. Preferably Hobart or Lincoln brands. You can actually use as small as .020 flux core wire, with the appropriate feed wheels and contact tip. It is not suggested though, you will go through a lot more wire that way. If you can find the tips for it, .040 can be used with the .035 feed wheel. Before you do that, check the next hint.

4. Check this thread (http://forum.atomiczombie.com/showthread.php/6736-added-a-bridge-rectifier-to-my-welder) out. Believe me, this single thing will smooth out your welding immensely! All flux core wire is intended to be used on DC electrode negative, and the HF unit puts out AC. This makes excessive spatter, as well as a hard to control arc.

Good luck!

Same one I am using except mine is so old it was made in Italy.

Same welder i bought 4 years ago thinking it would last me a year. (also made in Italy.) 4 years later and guessing over 300 uses by myself and friends, its still welding fine. I've replaced the copper tips probably 15 times but there cheap. I also buy the more expensive quality wire like charlie_r mentioned. I also use "anti splatter spray" on the neighboring areas and just wipe off the splatter when it cools. If your serious about welding lots of stuff with a professional finish spend more money. If your going to build a few frames and a few things around the house this welder should be fine along with the anti splatter spray.

I agree, DO NOT buy the wire from HF! Better quality wire equals better welds.

HD has Lincoln and Tractor Supply has Hobart. My Walmart also has Lincoln but only one size and I don't remember what size it was. .o35 I think.

Got my welder yesterday, tried a sample weld today, boy, is it harder than it looks :) Lots of fun though. Will play more tomorrow with it. What setting seems to work best on 16g steel?
