View Full Version : New tig welder DC/AC

10-07-2012, 01:05 PM
Hi all, I just bought a welder TIG DC / AC down to make it shortly MALAMBO trike (19.8 kg.) But aluminum, I have a long way to achieve this goal because first I have to learn to weld aluminum with tig. My question is this, anyone have a manual for this machine (China) as the manual that came with this machine is not corresponding to this machine, look on the internet but I have few references to it and there are many controls to adjust I'm afraid to start experimenting without having any notion of individual controls, although it is to serve, I could not put in the correct values ​​to start experimentar.

Looks much like the Everlast welders and the Locost welder from China. Welding Tips and trick take about setting up these welders. I doubt there is much difference to the setting as your going to deal with the same Amps- preflows and post flows. SO I'd say follow advice from welding tips and trick- Googling should find you a link. Hope that helps. Also find a local welding friend is always helpful. I am considering going to Tig myself and have been watching all the tips they have.

Take a look at this YouTube video for an AXT-IT9250 (http://www.youtube.com/watch?v=TWPrtADRRRQ) TIG welder which looks exactly the same as yours. I have a feeling it may be the same welder sold under a different brand name, but with the same model number.

The video goes over initial setup.

By the way, be very careful when buying an auto-darkening helmet for TIG welding.

You need one that has a response time of 1/25,000 sec response time to protect your eyes from the arc initiation.

Anything slower than that is designed for MIG and ARC welding. And unfortunately a lot of helmet specs don't supply this info in their on-line specs which makes it a pain to find. I assume that you are in Central America and don't have a local Harbor Freight, but here is a link to the Chicago Electric (http://www.harborfreight.com/blue-flame-design-auto-darkening-welding-helmet-91214.html) helmet I use with my TIG welder. I really like it. Some things it has that are good to look for are a sweat band, sensitivity adjustment, as well as a shade control (this one is really common).

Thanks for the info on the mask, I have a steelpro Optech and live in South America, more precisely in Argentina and even more in the city of Corrientes

That helmet looks like it should be good as long as the rating is correct. .000033 is 1/30,000 of a sec versus the minimum 1/25,000 required for TIG so yours will protect your eyes better.

Note that there is also a sensitivity setting... I have light sensitive eyes so I started with the most sensitive setting and darkest lens setting and am working my way backwards for my highest normal amperage until I find the settings I like the best, so far I'm still on 11 on darkness and thinking about go to 10 using about 100-110 AMPs. Which means I'm pretty confident that I'll drop down to a 10 and possibly a 9 darkness when I start working with thin walled mild steel and even thinner walled chrome-moly tubing that will have me running 35-60 AMPs on average.

Note if it is solar, and you are only using it as a hobby helmet, advice I found is to put it out in the sun to charge the batteries every now and again if you have not used it in a while.

Also, most of the welder's here are ARC/Stick and MIG welders so you might want to join weldingweb.com (http://weldingweb.com/)'s forum also. They have a lot of professional TIG welders who are happy to give lots of technical advice, so be honest if they are over your head or you are having problems with a language barrier.
