Thread: Novice Welding Questions (Grahame?)

Cliff IMHO I would go with an inverter if you can lay your hands on one, with that wall thickness a stick welder can cause heaps of grief , you don't have much margin of error with heat , amps etc and holes in that thickness are a mongrel to patch. Should be cheaper than a mig cause you won't need gas .

Rgds

Right, beauty.

What is an inverter.

until Grahame trots along, I say get exactly what Ding got and it will be a breeze. Just like sticking them together with a hot glue gun its that easy. I would strongly recommend getting a bottle of Argoshield light and a regulator though.

Someone round here told me that it was a device that changes 2 phase power to three phase.

1200 welds?

Mig is the only way to go! no chipping, no mucking around.

By the time you buy enough rods to do that many welds, the gas is easily the winner. Also, you won't have to change 500 rods.

Again, no slag to chip either.

Finally, even with an inverter (in stick mode), you're still stick welding.

I've worked out that I am faced with about 1200 30mm welds.

How would you recommend I go about this?
Stick welder or a MIG like Dingo has been raving about?

Hi Cliff
What !nearly 200 meters of SHS. Who luvs ya! baby?

Cheap
Speed
Quality

You can have any two of the three.

The mig will have the edge there Cliff, not only only in the flat horiz positions ,but can handle out of position,vert down ,vert up and overhead as well. It will give you a near flawless job if well set up.

If you want a bit cheaper, Ashore is correct that the inverter will do the job in the stick department. If you have stick welded with the old stick machines the inverter models will change your opinions on stick welding. I have had mine down to 32 amps with a 1.6mm rod.Yes folks ,you can buy them and 2.0 mm as well. A local crowd M.I.G. that's Mackay Industrial Gases, that sell them.

Even if the box is gal, all you will need is a flap wheel to clean em up and your away.

Crikey? What you have saved on the the tube you can spend on the welder.Gas you can hire by the month.
yep! Dings welder looks like a great product.Cigweld is still Aussie, last time I checked.

Gee! some blokes are tinny

I know, I know, the local Tonkins had 20x20x1.6 for $15something a lenght & 25x25x2 is $21something a lenght on special, so I am somewhere between $450something & $630something in front.

It isn't Gal, it is blue painted but it is several years old 'cos the project it was bought for never happened.
Technically my wife's family farm owns it & it is just sitting there going rusty so my BIL said I could have it.

OK, where is that thread about MIG welding.

Wot ? I have n't done one?

I am truly suffering from stress.Ah! no its CRAFT!
If theres nothing in the archives I'll cobble something together.
Until then is this OK ?

Cliff do have a friction drop saw? And perhaps an angle grinder.It will take the little 1mm cutter blades which are superb for inletting. Also for good for your flap wheel.

If you design your shelf the right way, the rolled edge of the box against a cut square edge makes a ideal half vee (sorta) weld prep . The weld bead, deposited the right way will flush up with the surface and won't need grinding and super strong to boot.

How about a Triton Cold Cutter & a Piric Design Blowfly?

I'll read you Mig thread & I'll go over the stuff you posted in Ding's thread too. Thanks.


PS. What is 'inletting?'

G'day Cliff,

What is "SHS"?

Have you moved, where is Minbun, and where does FNQ start and finish, I'm pretty sure I am close to one end

Cheers, Jack

Square Hollow Section.... not RHS.

About Cardwell I think, Townsville is NQ, Mackay, Rocky & Gladstone are CQ.

Minbun is between Tarzalli & Millaa Millaa.

Southern Tablelands.... East Evelyn area.

You are now off one end of FNQ.

Crikey Cliff ! You got some nice toys.Both will perform admirably.

Inletting is ,say you want to set the end of a cut into the edge surface like a mortice inlet. The thin kerf of the wheel allows it to cut like butter through thin wall steel.
A plunge cut across the parallel to suface cuts the section out.Any over cut can be filled with mig and ground /polished off.
I will do a pic on the week end, if I think of it.

Jack ! RHS rectangular hollow section.
SHS Square Hollow section.

in CQ

In that thread you said....

I will post a new section on setting the GMAW machine up to weld when I am feeling a bit more able.I have got a touch of carpal tunnel and my right arm is giving me pigs rrrs.

I hope the arm is good again now.

You did post some tips in Ding's thread, I'll read them too.

Well there you go, I've never heard of SHS before.

In NQ (which I just left) RHS is Rolled Hollow Section and is square.

Don't know what it is called up here in OOEOFNQ (Off One End Of FNQ)

Cheers, Jack
