I had the question this week about the aluminum welding with the Miller mig Challenger. Thank you all very much for the input.

My question is that I am considering purchasing a Miller 250 tig and I wonder if this unit is a good tig unit for meeting my welding needs. Lots of aluminum to weld and some small tractor and farm welding(I could use the stick)

To help pay for this unit I was going to trade my challenger in. Can I do things with the tig that I could do with my Challenger?

I can hard surface with my O2/Ac unit.

Do I need a cooler unit with my 250? Also I was going to get the hand dial instead of the foot pedal, is this a good dial unit?
Hand dial would better suit my needs.

Hi Mark

I've had the Miller Synchrowave 250 for quite a few years, it is a very nice welder. I added a PC 300 Pulser and built a cart for mine. The only way I think Miller could improve on it is to incorperate a CV feature into this welder allowing it to be used in yet another process [MIG/SMAW] with a feeder or better yet a suitcase welder [Lincoln LN25]. I have the foot control on mine and sometimes wish/need the hand control for out of position welding. When you get to using over 150 Amps you'll need a water cooled torch.


In comparing the Callenger to the Synchrowave is sort of apples to oranges as there is different welding proccess involved. TIG will allow you to weld any weldable metal with a higher quailty weld although slower.

The Synchrowave is my least used welder [for what I do] with the engine driven being second and the MIG being the most used.

Check out Lincoln's Power Mig 300 in the K1694-1 and the K2177-1 and see if it may have the welding Process that you require.

I've got one, excellent machine. You should get the water cooled torch and rad. This unit was made for welding aluminum. Tig gives you a much wider range of metals you can weld and much better welds. I'd say a very versatile machine with lots of amps. No problem stick welding. I bought mine used at a very good price, new they are kinda pricey with all the accessories.

Is it easy to learn tig? I have never welded tig but I am confident that I can learn.
I will do mostly 1/8 al and 3/8 to 1/2 steel.
What tungsten tips should I consider, 3/32, 1/8?

I'm just learning Tig to but I would try to use 1/8 tungsten for all your aluminum welding if all you will be welding is about 1/8 AL. I think you could use 1/8 tungsten for most of the steel you will be welding to and try lanthanated tungsten�s you can use them for AL and steel. Sum help full links posted below.

I started out using a gas setup and find tig to be fairly similar in technique. Main advantage is instant heat or just about. Easy to see the puddle. I find stick welding harder cause most of the time I can't see what the puddle is doing. Electrode size and type depends on metal thickness and width of weld desired. Thoriated tungsten is better for aluminum than pure tungsten but it also costs more. Alot also depends on your level of skill, practice practice practice.

Before you run out and drop $2000 - $3000 on a TIG welder I would try to track down a trade school to at least get a little hands on TIG welding experience. TIG welding is considered the hardest of the four methods of welding. I�m not saying you can�t learn to TIG weld but it would be good if you could get a little schooling on it especially with the amount of money your talking about. I went to one of our local Junior Colleges one night a week here in the Dallas/Ft. Worth area to learn how to TIG weld. Call around to some of your local welding supply stores and ask them if they know of any welding schools in your area.

I have spent the last 3 days helping the local Community College instructor. He has 43 years of experience and is also a certified welding inspector.
He said that at the end of the year the CC is going to drop the program and probably offer up their unbelievable supply of welding and machine equipment.

Thanks for all your help.

Mark
