Question: Purchased this item and used it once to weld two bed frame legs.  Got the unit out today and it does not work.  No arc.  Fan works fuse ok any ideas?
Document: this welder is an ok welder if you are only going to be using it once in a great while. I purchased this machine and in a matter of a week I was looking for a new welder. I purchased a Lincoln weld pak100 and I was glad I did you can tell the difference in the weld quality and just over all quality of the machine. That being said this welder is not all bad it does weld its not pretty but it will stick metal together and it does run off of 110v.
Firstly I should say that I am a novice welder and I will only be welding occasionally. I bought this unit in order to repair a go cart. It was my first time welding and I learned just by watching Youtube videos. The welder is easy to set up and comes with a spool of flux cored wire. The unit comes with a very basic hand-held face mask and a light filter. I tried to use this and it was a miserable experience.
I'm not actually a welder by no means but some of the people I hire are and they seem to have no problems with this welder. One day the worker didn't show up so I tried my efforts at the process....well not only does my weld not show up in any of the charts that depict what a good, average, poor, etc.
I went out and bought the cheapest auto-darken helmet and WOW what a difference. After about 10 minutes of experimenting with the speed of the wire feed I started to weld the go cart. I was able to make a nice 'puddle' bead as a weld and after I brushed the slag off the weld looked pretty good but had a few bumps. I ground the weld down and tried again and this time it came out perfectly. The weld looked just like the others done at the factory.
Iv had this welder for about a year now and its still going strong ... I welded my side steps on my truck and installed my new muffler and made my own lil utility trailer with this welder .. I got it for 80 bucks at my local harbor freight store with a coupon .. .. totally worth every penny .. new project is dropping my truck
The welds have tested out fine and have held up beautifully. I would have given 5 stars except the supplied mask is pretty awful. Spend a few bucks and buy a better (LCD) one.
The welder has a tendency to overheat due to a low duty cycle. The wire feed is not very smooth witch leads to poor looking welds. So over all I would say unless you are not looking for quality and nice looking welds or if you have to do a one time job stay away from this machine.
It's working fine.
Answer: no
