FQA
Q. How to set power source when using TIG welding?

Your welding machine should be set to DCEN (Direct current electrode negative) also known as straight polarity for any work piece that needs to be welded unless they material is either aluminum or magnesium. High frequency is set to start which is found built in nowadays in inverters. Post flow should be set at least 10 seconds minimum. If A/C is present it is set to default setting that coincides with DCEN. Set the contactor and amperage switches to remote settings. If the material that needs to be welded is aluminum polarity should be set to A/C, A/C balance should be set to about 7 and high frequency supply should be continuous.

Q. How to set shield Gas during TIG welding?

TIG welding uses the inert gas for shielding the welding area from contamination. Thus this inert gas is also stated as shielding gas. At all cases it should be argon and no other inert gas such as neon or xenon etc especially if TIG welding is to be performed. It should be set around 15 cfh. For welding aluminum alone you can make use of a 50/50 combination of argon and helium.

Q. How to choose TIG welding torch?

There are a lot of different kind of torch can be used. But according to the chilling method, you have air cooling TIG torch and water cooling TIG torch. And also, the Ampere will be different, some of them can bear 250AMP, while some of them can only bear 100AMP.

Q. when should I choose water cooling TIG torch and air cooling TIG torch?

You should choose water cooling TIG torch if there are a large quantity of pieces need to weld. But air cooling TIG torch will be a good choice if your pieces is very few.
If you have thick pieces to be weld, water cooling TIG torch is better than air cooling TIG torch.
