Welder buying spam

Oh yay tig spam my favourite

Everyones got an opinion but I believe that basic HF Tig are the same as Arc machines. Unless you buy a super cheap import one any machine will do for what you want it to. I roll a 15 year old tool shed HF tig only goes to 150A but 10/10 would trade again. Nothing fancy just controls Amps and post flow but have done everything from rusty panel repairs to multiple pass 10mm plate welds to 5mm production fusing. 

As far as new welders go a friend has 2 basic hugong Tig at his work for panel repairs/chassis fab and rates it highly for temp control etc.

Whatever you buy make sure you budget another $200 for some accessories as that is where you get your usability from. Flex head is a must the Aliexpress ones at $12 are identical to the $50 from our welding supplier. I love my gas lense usually roll a 7 cup and am yet yo have a job where I cant push the tungsten out enough to get into tight spot. The generic cup kit off alixpress with the different cups and pyrex lenses is a really good place to start as its cheap and the cups are all really low profile, good combo with the flat back cap for getting into cunty spots. 

Live having different size rods on hands really helps when doing the end of each scale jobs. Thin stainless wire is great for repairing everything and have some 2.4mm steel wire for gapcraft jobs.

Hope this helps.

MIG / TIG use different gas IIRC, so go with the gas to suit the process you're using.

I roll co2 and MIG, because I own the cylinder. Argoshield (for MIG) seems to be a better option.

Not sure what the quality is like but these are on trade special at Bunnings at the moment.

Quite keen on that but notice amps only go down as far 40a on mig. A bit high for .8mm steel?

 

Also doesn’t seem to be able to use .6 mm wire?

I don't have that one, but it looks to have all sorts of adjustability. Mine has a similar level of adjustability and I just wang the voltage / wirespeed / amps on whatever gets me a decent result. I never weld car panels at the lowest setting anyway as usually tack, tack, tack. If you plan to run beads on thin steel the lower settings might be needed. Wouldn't surprise me if it came with the 0.6mm roller / can probably order one if not.

I see mitre10 has them, I wonder if they'll price match so I don't have to pay shipping...

They will, but you might have to push them to ring up and confirm some details as the waitemata hydraulics website doesn't explicitly list the model number.

I had airpoints dollars to use otherwise I would've just gone through waitemata hydraulics

Hello welders,

I know its been asked multiple times. But I'd like to re-ask to get the latest opinion.

I'm after a TIG. Would like to do Mild, Stainless, and very likely alloy in the near future. I've already got a MIG, so after a dedicated TIG machine.

What of the current range would you people recommend? (I've seen Kicker's question on the previous pages but would like a few more suggestions if possible :))

Would it be best to not get one that does alloy? Will most likely be used for panel steel, exhaust pipes, and on occasion 5mm plate for brackets. Anything thicker will get the MIG treatment. So doesn't need to be a gajillion amps!. However, for alloy, I would likely be for repairing damaged motorbike engine cases and covers, so may need some amps for that??

Would like to hear pros and cons for DC only or AC/DC units vs price. Best to fork out for an AC/DC unit so i can weld ally in the future?
I don't actually need to do any alloy welding immediately, will be mild and stainless for the time being, but don't want to trap myself and need another outlay when i want to do some alloy.

Many thanks.

Anyone know what the norm is in industry re welding stainless steel. Fuck knows where I have been all my life but I've never had anything to do with the stuff and always thought it had to be TIG welded. Not totally true because when I purchased an old welder years ago, I noticed it came with some arc rods for doing stainless. I put this down to this is what they must have used back in the day' given the welder was from the 1950's. But anyway - yeah TIG. But then I came across a clip on YT showing a guy MIG welding stainless so throwing all of my preconceived views out the window. So question - how is stainless normally welded in industry? Anyone know?
