links for welding info

while we ALL wish that we could get QUALITY tools cheaply and THERE ARE bargins OUT THERE TO BE HAD!
BTW a FEW places to look over and ask QUESTIONS
IM no expert on welding even thought Ive been welding for 35 years PLUS, ask MANY QUESTIONS BEFORE YOU PURCHASE A welder, and be SURE you understand the answers also ... index.html ... ideos.html ... ig201.html ... index.html ... &forumid=3 ... equip.html




First I’d like to say I’m not an EXPERT at welding but have done quite a bit over the years.
Now to answer some basic questions. Here is some info from a different site you might want to know!

I'll try to explain some of the basics for you as best I can.

TIG - (Tungsten Inert Gas Welding)Basically resembles oxy-acetylene welding (torch) but you use a controlled electric arc as the flame/head source and feed in the weld wire or rod separate from the arc.


This process is the toughest to learn. The electrode is composed of Tungsten and current flows through it. The current is controlled by a foot pedal, hand switch or fixed current on the machine itself.

I am learning TIG using a foot pedal The more you press down on the pedal, the more amps you get. Once you get enough current flowing to get an appropriate sized weld pool, you start dabbing filler metal into the puddle as you move the electrode further down the work piece. TIG allows you a great amount of control because you regulate how much current the electrode gets and how much filler metal the weld pool gets. This process is very slow compared to the other types welding.

MIG - (Metal Inert Gas) MIG is basically a wire that has current running thru it, that is fed constantly into the weld area. It melts both the metal and itself as its consumed/melted by the arc.

MIG is the easiest type of welding. A feed gun is used to feed metal wire from a spool into the weld pool. Current and wire feed is usually switched on and off by means of a trigger on the gun. A dial on the MIG machine usually controls the amps and you cannot adjust current while welding. With some machines you are able to use a foot pedal to control Amps while welding.

Arc Welding
These are the cheap buzz box welders we usually start with. They use an arc thru the weld rod somewhat similar to MIG but without the gas shielding. They have flux on the rods that produce shielding as it burns, to help the weld quality.


Arc welding is mostly used in industrial applications. An electrode is used to strike an arc, then the electrode melts away to deposit metal into the weld pool. The electrode is coated with a variety of different materials, which are used to help keep the weld pool from being contaminated.
a bit of related reference material helps




TIG and non-flux-cored MIG both use a variety of different shielding gases to help keep the weld pool from being contaminated depending on what metal is being welding. ... ng_basics/

Very useful thread. Thanks for this post!! This will be useful for many. Initially, I was a YouTube fan and I started my welding with the help of YouTube tutorials. I have learned how to weld and I have had many doubts cleared with the help Youtube but sometimes they can lack perfection because there were minor mistakes in my work. I thought about getting someone's assistance to correct my mistakes so I decided to join 5 days TIG welding course next week. I think perfection comes only with proper training. I hope that I would get some detailed knowledge from there.

well I'M very happy to see these links and sub linked info does occasionally get read!
and yeah, nothing beats hands on practice with a knowledgeable instructor who can correct mistakes,
and point out ways to do things a bit faster or ,
make a more consistent and stronger and better looking,weld.
keep an eye out for any place like that welding shop that might be moving or closing you might be able to score a good financial deal,
on a used welder, most places would rather make a few hundred bucks rather than store older equipment as they would generally prefer,
to upgrade the equipment at the new location or when they restart the business.
you might also look for adds in the local craigs list or bargain trader magazines.

yeah freely admit I'm a tool junkie
ebay (look for local adds as the welder would ideally be tested before purchasing it)
