Can I weld an exhaust with this?
If you have to ask, you won't have the skill.
arc is more suited to thick metal
.So yes, and I'll develop the skill
Car exhaust? Maybe 1mm thin? Yeah nah
.I have never welded in my life either but I purchased one to learn the skill. It could come in handy around the home or car.
@Windows7forever: should buy a welding machine for what project you plan on using it for.. MIG would be easier to learn and more universal than ARC. ie. thinner metals.
Should do a short course at TAFE and then the rest is practice.
@Dr Techno: yep, I did that 100 yrs ago. Tafe excellent. Just check power requirement. Some points at home drop out at 10amp .I put in a 15 so I could use full power when I was making a trailer. MIG is good but wind is a pain outside. Coated wire with MIG would be better but expensive.
@Windows7forever: It's a cheap way to get started for sure.
But don't skimp on PPE..get an auto darkening helmet and gloves
@edrift: But you can get that summer sunburned look for $49 … and snow blindness too. It's like all the seasons at once.
Better off with TIG or MIG welding for car exhaust.
Yes you can I have welded exhausts with a stick welder
clean the area to be welded lower the amps and use thinner rods start with spot/tack welds
It probably wont be the sexiest of welds compared to a mig but if its under the car and does its job who cares?thanks for the advice
Yes you can. It will be difficult and likely not look pretty, but it is possible.
I stick welded my exhaust. First time ever using a welder. Blew many holes through. Quite frustrating but a good learning experience
100amps is quite small for an arc welder it seems.
Would this limit its uses much?Depends what you are welding.
I've always turned mine right down to stop.blowimg holes through things.
Just use smaller rods for these small welders :)
So tempted, only have to buy this and gloves, mask, wire and learn to weld so I can occasionally fix those balcony railings
OR
Pay someone else to do it
It'll pay itself off in one job.
Auto darkening helmet is about $50 off Ebay, rods are $20 a pack, gloves surprisingly cheap $10.
Tradie call out fee - same cost before they've even started working.
edrift Auto darkening helmet is about $50 off Ebay
just a bit of information on those cheap auto darkening helmets is if you are doing a lot of small quick welds or welding in a difficult position you do get a little welders flash they are better suited for the bigger longer welds
i prefer the head nod with a traditional welders helmet and always grab that over the auto darkening one i haveSo someone on here posted something about them.
I think I watched the YouTube video too.
Apparently the passive lenses are enough to protect you against most of the dangers, even if the auto darkening is slightly delayed.
I don't weld a whole bunch afaik my helmet is ok.@edrift: Correct, the UV is filtered all the time. The auto darken is just lowering light levels. So no real risk to your eyes if slow to darken.
I could not do without an auto darkening helmet so I don't have align the rod and then nod my head to close the visor. A fantastic tech gadget :)
Time to learn how to weld
How hard can it be…
49 bucks, worth a go given that it comes with a warranty.
Great find, thanks
can we use this one to weld beam for retaining wall or fencing?
Yes
Thanks OP, got the last one at my local for 39 with the discount. Took 10 Min to activate but luckily no one else bought it
Just a word of warning. It overheats quite easily and takes a while to cool down before you can start welding again as it does not have a cooling fan. I had to install a 12cm inside my similar welder to assist with the cooling.
Strange. On the specs is says it has a cooling fan. How did you install a fan? did you solder it to the main board?
My mistake. The one I got was from ALDI which did not have a fan and I had to wire a 12cm 240V fan inside. The 10% duty cycle means 6 minutes of welding in 1 hour which is only OK for a very small job.
Did the tafe course on stick welding over 5 thursday nights last year, can't recommend it enough.
Ended up with a renegade stick welder off marketplace which does great for the price, plenty of people seem to muck it up once and never try again.
Made myself up a fireplace from a 44 gallon drum and some star pickets, works a treat.I did similar course a while ago over 10 weeks at another VUT TAFE which was fantastic :)
Is it an indoor or outdoor fireplace? I have no idea what that might look like
Sorry, meant a firepit. Cut a barrel in half and made a frame out of star pickets. Welded it all up together and it works great
Price should be $49 in title imo
