Just wonder if anyone has had any experience/knowledge on welders out there at the moment.

Just after a home handy man style. In the past have only used arc welders but know there are mig and tig versions around. Now I dont want to deal with gas bottles so gasless migs have caught my interest. What are the pros and cons when I can get a arc welder for $100 and a gasless mig will be $400 worth. Can it still do aluminium.

Thanks

You don't want much. You'll need to pay at least $700 retail for a decent handy gas/gasless. Gasless welds are crap so get the gas bottle. It will do ally and stainless but you need pure Argon for them and Argoshield blend for mild and other steels.

i have a gasless and gas based welder .. was bout $550 and it can use either small 400mm high gas canisters (single use) and normal gas bottles and gasless wire.

atm im just using gasless wire which is good for using the unit as a portable... can have bottles for nice proper welding in the shed

Its been a while since I welded ali but I think you need pure argon, and no, a gasless wont weld ali. In the industry no one use arc welders any more because they are a pain in the ass, we either use mig, tig or inverters. Inverters are the best in my opinion as you can use rods or set them up for tig, but to weld ali with tig you need a square wave unit which are very expensive (4k). If you set up a steel mig welder to weld ali you must remember that ali wire is very soft and bends easily thus getting caught up in the wheels that push the wire, a dedicated ali mig uses the push/pull system with driven wheels in the hand piece that pull wire up to it.

I think you'll find you will need to pay for a license for the gas on a mig. So unless your doing a fair bit of welding it probably won't be worth it. Might be best to get the arc welder. Personally I think a nice weld on an arc comes out better looking than a mig anyway :D

I m not sure on this either but nowadays I think you pay for the gas and hire of the bottle, so if you have it for a year without using it you still pay for just having it.

thats spot on ...

with the welder i use... you get small canisters fo gas that are single use... good for the not so often welding.. and can run the gasless wire as well, and be able to hook up a proper small sized bottle for big jobs ..

Gasless is Mog not mig

Gassless is only for very light welding stuff ie 1 or 2mm steel or wire. My uncle had one, and it was useless to use...u need still or no wind at all.

Mig for home would be any of these : http://www.welding.com.au/products-listing...?iCategoryID=63 (as they are single phase) they require a 15 kg roll of wire too (it can go rusty which is useless) if u dont use it all

Gas bottles are rented per year ^ and u have to buy gas. They can do aluminium as said which requires ally wire.

then theres tips, nozzles, etc which add to costs .

Tig can do anyhting u want, but costs $$$$

Nice enough welders but the smallest needs 15 Amp plug so it's not really portable or a direct plug in until you get a 15A outlet installed.

Once more, the Ally and stainless needs pure argon but mild steel uses Argoshield blend.

Go to BOC and talk to a salesman, they'll put you straight.

Oh and for a TIG to do ally would be over 4K.

    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
