madali lang ba matuto ng stick welding? balak ko bumili nung murang welder para DIY na lang ang welding ko para sa mga projects ko. nagbabasa ko sa mga "how to" websites eh, mukhang hindi naman masyado mahirap, kelangan lang ng practice. ano ba masasabi nyo guys?

Hi oakley. The answer to your question is "No, not really". It does however take practice, not that I'm expert. Sure do read as much as you can. There is lots of stuff on the Internet. At the end of the day, it is all about practice.

Make sure to have the right safety equipment. Some professional welders use dark glasses instead of a mask or just close their eyes - don't do it. Buy mask and welding gloves, seriously. I myself also try to get myself to wear safety glasses or a face shield, over which the welding mask goes. Those dark spots you see on a pro's face, and even eyes, are from the hot black stuff covering a new weld that tends to shatter as a weld cools. Safety first.

Don't get me wrong, I'm not saying don't do it. Welding is a lot of fun and it can save you a bundle if you do enough of it. Just be careful. Do the homework, and stay safe.

You are referring to electric arc welding, quite easy once you get the hang of it........just be careful in tapping onto your mains. Welders mask is a must lest you want sore eyes. HTH!

This welding machine is I think worth a try if you want to practice.

i've decided to buy a second hand MIG (GMAW) welding machine. mas mahal kesa sa mga brand new na stick (SMAW) welding machines pero according sa research ko ay mas madaling matutunan ito at lower ang cost ng mga consumables. mas versatile pati ang range ng thickness ng materials na pwede pag-gamitan. diko pa nagagamit kasi kelangan pa mag-setup ng 110volts na outlet sa amin. this week siguro magagamit ko na. bumili nrin ako ng leather welding gloves tsaka yung prang goggles.

Good for you Oakley. I heard the same thing that MIG is easier. Also you can get Class A results if you use an inert gas shroud, more expensive to operate but you can perfectly weld metals you would normally not be able to.

TIG I'm told is the best in terms of versatility and performance however the cost is high, as is the skill requirements.

Bro, 110v? Be careful, welding machine draw a lot of power. A true 110v circuit would be best not that "wire in the earth approach".

Better if you have a mask and not just goggles. It would hurt terribly if a hot shard landed on your cheek.

just last week i've started practicing my welding on gauge 16 sheet metal. gumamit ako ng "arcoweld" shielding gas (from INGASCO) which is 80% argon and 20% co2. madali lang pala to gamitin pero sa mga certain types of joints mejo kelangan ko pa ng practice. wala naman masyado spatter kaya kahit goggles lang ang suot ko, di pa naman ako natitilamsikan. kaso, humapdi ang mukha ko the morning after. nakaka "sunburn" pala hindi ko alam. bibili na rin siguro ako ng mask. gusto ko sana yung auto-darkening na mask kaya lang medyo mahal at hindi kasya para sa budget ko sa current project ko ngayon. i'm using .8mm wire for mild steel. may flux cored wire din ako pero hindi ko pa nasusubukan.

You got sunburned because the arc gives off a tremendous amount of UV radiation, no kidding. If you were thinking of using just a regular face shield that might not do but I am not sure. Best of course is a real welding mask.

@ Oakley

Bro , how did you set up the 110 Volts power source?

Do you mind sharing how much you paid for the MiG Welder and what brand is it so we will have an idea.

tks

BTW : Lots of Mig welding info on this site :

hi, sorry i've been quite busy this past year kaya ndi nako nakapag forum. we asked an electrician to connect to the ground line on the electric post in front of our house. I'm using a Lincoln Promig 135 weldger. I bought it 2nd hand for 20,000. If you look mig welding machines on the internet I think it's cheaper. The previous owner told me he bought it from the states and carried it with him on the plane trip home. Before I bought it, I looked for brand new MIG's being sold locally pero nasa mga 40k Php ang price. Siguro pang heavy duty. Ewan ko lang ngayon kung meron na mga available na mura. So far, ok naman ang performance nung machine. Tamang tama para sa sheet metal.

Maki sali sana ako - I'm interested with learning how to weld too. I saw a small MIG welder in Olongapo for 7.5k - one of those surplus shops. Hindi ko lang alam kung complete siya with parts and everything.

Now how do I start? What should I get MIG, TIG or ARC? I was thinking of MIG.
Oh yeah I checked out the other topic about stick welding - very informative makes me want to go out and buy a welder right away :)

Bro, I'm not an expert. I've only used arc though I dream of having a TIG welder some day. I've got my mind on TIG based on what I've read. MIG is easier but it is more expensive because of the wire feed. TIG is harder but more versatile and less expensive.

If you can afford it go with the MIG. No brainer daw ang MIG welding, very easy. Just put the head to the weld point and press the trigger. Arc startup is automatic, feed is automatic, arc maintenance is not an issue.

Hmmm... Thanks there is an advertised oizito 90amp mig welder for 5k i think. OK na kaya yon? Is the Amperage rating of the arc welder just the same as a mig welder? Masyadong mahina kaya yung 90amps?

One more thing nakalagay gasless mig

bbn
02-19-2009, 04:08 PM
Well it being gasless is why it is so cheap. It being Ozito is another. Personally, I don't like the Ozito brand. I'd rather pay a little more for a brand with higher quality.

I'm not really sure if gasless is OK. From what I've read the gas shield is what makes MIG and TIG welds so much better.

Thanks got it!! I think I would just start with stick via a 160amp welder. Thanks for the advice

bro, what you refer to as "gasless mig" is technically called Flux-Cored Arc Welding (FCAW). It uses a flux-cored welding wire which contains something that floats over the molten weld pool so that the metal does not get weakened by ambient air during welding. Nagreresult kasi sa mahinang welds kapag nag-contact sa hangin habang tunaw pa yung metal.

Yung "stick welding" is technically called Shielded Metal Arc Welding (SMAW). Yan yung gumagamit ng welding rods. Yung nakabalot sa welding rods na parang matigas na powder, flux din yun. That's why you see those black ceramic-like residues on top of welds using this process. Yun yung tinitiktik at nililinis na nasa ibabaw.

Yung MIG na tinatawag ay Gas Metal Arc Welding (GMAW). Instead of using flux to protect the molten weld pool, it uses shielding gases such as CO2 or Argon+CO2. Advantages of GMAW include cleaner welds & easy to hold and maitain the arc. Mas malinis yung welds kasi hindi na gumagamit ng flux. Kapag maayos ang weld kahit hindi na i-grind. Mas madali rin hawakan kahit siguro mejo pasmado ka hindi ka mahihirapan i-maintain yung distance ng electrode at workpiece. Dahil ito sa automatic wire feed.

Yung ginagamit kong MIG welding machine pwede rin mag FCAW, yung gasless process na tinukoy ko sa taas. May mga konting spatter lang pero ok naman. Ang advantage nya is it can be used on thicker workpieces. Yung mga iba kasing wineweld ko kapag makapal na, kahit naka-todo na yung amperage setting ko, hindi kaya kapag nag MIG ako. kapag ginamitan ko ng FCAW kaya nya. Kapag FCAW, madali rin itutok kasi may auto wire feed.

Yung SMAW naman, na gumagamit ng welding rods, mas bagay kapag makapal ang iweweld mo. Mas mura pati ang equipment. Kaya lang mahirap yata pag-aralan kasi kelangan talaga matuto ka na itutok ng maayos yung electrode habang nauubos yung rod at habang ginagalaw mo yung weld along the workpiece. Yan ang narinig ko. Dipa kasi ako nakapag SMAW. GMAW pa lang at FCAW.

Yung TIG (TGAW) sa mga super clean and super beautiful weld finishes ginagamit. usually kapag mga aluminum, TIG yata ginagawa. Gagamitin mo dito parehong kamay. One hand for the torch the other for the metal filler material. Mano-mano ang pagload mo ng filler material dun sa weld pool. Parang acetylene welding din, ibang torch nga lang ang gamit.

Siguro sa pagpili ng welding machine kelangan i-consider mo kung ano ang iweweld. Gano kakapal na mga bakal. Kung mga sheet metal or others na under 2mm dapat MIG or TIG. Mga up to 1/4 inch FCAW dapat, or depende sa machine pwede pa siguro mas makapal. The rest, SMAW na.

Marami nako nagawa dun sa binili kong MIG welder about a year ago. Para sakin yung pagkakaron ng auto wire feed kapag nagwewelding malaking tulong talaga. Ang price ng consumables ok naman. Yung shielding gas na binili ko nasa 800, yun yung nasa 5ft na gas cylinder. hanggang ngayon dipa ubos. Nakaubos nako ng approx 3/4 nung isang malaking spool ng welding wire, eh nasa 5 kilos yata ang isang spool nun, diko lang sure, basta mabigat.

No gas, I dismantled a Microwave. Then used the transformer. I removed the secondary coil entirely. Rewound the wire with AWG10, until it measure just above 12V. I used a Bridge rectifier of 4pcs 6A diodes and 2 supercapacitors rated 50VDC. Now I have 12-17 volts DC..
If it has load, current is around 10-12V.. (im still working on installing a relay switch to make the charger automatic.)

About the carbon arc weld. I made slots to install it on (AC), (DC+). (DC-)

I fabricated a torch to hold carbon rods.. It burns a bit like stick welding, but a little less since its just 12V and 15A..

As of now, I find it hard to look for carbon rods, so I recycle old batteries, using the center carbon core. Use it like a TIG, you'll need a filler metal to weld thin sheets together, sometimes I use thin wires used in flowers, sometimes copper.. Its better to dip it in borax solution.

Anyway, I also installed aluminum heat-sink, and cooling fans. I used a bleed resistor for the capacitor,so it wont burst upon over charge. Also a installed a 15A fuse.

Still planning to install a Voltmeter and an Ampere gauge to monitor current spikes.

Toying on the idea of building some support so it can carry long pieces.

Paranga mahirap yata kabitan ang Rav4 ng ganito. Sa ilalim pa mountings.

Good day mga sir! gusto ko rin matutong magwelding.And Im planning to buy an ozito brand MIG welder `120 amp,gas/gasless.Ok na ba ang machine nato in terms of quality? Another important thing is pwede na ba kaagad to gamitin dito sa pinas without the use of power converter? 220 volts 50 hertz (australian) kasi ito.Ours is 220v 60 hertz.Gagamitin ko lang at home.Maybe automotive work,making a bike stand or probably panggawa lang ng patungan ng mga paso.

Hi jamertan,

Bro, its nice to know that you are somehow interested in this machine too but before you buy a welding machine , here's my two cents worth of reminder/advice.

Do research well on the welding machine you mentioned and do research also on other welding machines available in the market. Compare their pros and cons, since you will still be learning the process of welding, also consider your budget limitations, I'm trying to be practical here bro, branded welders are expensive so select your welder well. For starters get a welder not less than 200 amperes, it can be AC which is plenty in the market and less expensive or a DC welder, of course this is more pricey but gives out good welds. :)

With the OZITO welder you mentioned, why don't you read some replies here by other members who managed to purchase the said welder and from there may be you can have an insight of its capabilities. Purchasing a MIG welder is sweet to hear but with the Ozito welder you will still have to convert it to DC welder to be able to attain a considerable good welds, so that means you will still have to shell out some additional cash for its conversion.

Like what I have said do research first and do your homework so you will understand and know the right welder for your intended applications. GOOD LUCK on your choice !!!! ;) :rolleyes:
