  • Portable Yamato 300 amps

    Hi guys
    I am planning to buy either a portable Yamato 250 or Yamato 300 Amps stick welder. What are the pros and cons of both these machines if they are compared with each other. The difference is only 400 pesos. I will be using it to weld metals about 5mm thick. Oh yes, the seller told me he has no 250 Amps in stock but has 200 Amps and 300 Amps.
    Which model should I go for?

    If i were you i will go for 300 amps..hindi mo naman masasabi na puro 5mm lang ang i weweld mo..saka 400 php lang naman ang price difference..better over specs than not..

      Bro MelWelder,

      First of all what type of Yamato are you using, is it the yellow bulky Yamato or the portable stainless body type of machine ? I also own a Yamato 300 Amp AC machine, its the yellow bulky one and its settings reads from 60amps as the weakest and up to 300amps as the strongest.

      I suppose yung readings mo sa iyong Yamato ay # 1 is the weakest and yung # 7 is the strongest. Pwedeng ang readings mo ay 60amps for # 1,
      90amps for # 2, 120amps for # 3, 140amps for # 4, 180amps for # 5, 240amps for # 6 at 300amps for # 7. Ang mga settings na nabanggit ko ay similar sa aking Yamato 300 Amp AC machine. Mag test weld ka ng settings na #s 1 and 2 para sa medyo manipis na steel plates tapos mag test weld ka rin ng #s 3 ans 4 settings sa makapal na steel plate o bakal para makilatis mo ang mga pagka kaiba.


      Hope this helps !

    Re: Portable Yamato 300 amps

    Are you getting the AC welding machine ?? My say to this is that better get the 250 amps DC arc Inverter portable machine. This will be enough for you to weld any thickness you may encounter in the future. 250 amps can weld from 1/16" thick plates up to 3/8" or perhaps 1/2" thick steel/plate with a multiple passes.

    If your seller does not have an available 250 amps DC machine, then better find other sellers that have or carry this specs. DC Inverters are better than simple AC machines in terms of electric consumption, good starting welds, better penetration and less spatters. This type of machine can be plugged in an ordinary household outlet. See if you can get a RILON 250 amps DC Inverter weld machine, it can suffice for light or heavy duty applications.

    Medyo mas mahal nga lang ang DC compared to AC machines. But if you insist on the AC machines, then its your choice.

      Yung 200amp na dc weld, kaya b nya yung babad or yung uubos ng 1 stick in one shot. D kaya magprotect? Bibili kasi ako, iniisip ko kung ac na 300amp or dc na 200amp.

    Re: Portable Yamato 300 amps

    to the TS, kunin mo na yung mas mataas ang amperage kung ganyan din lang ang price difference. me too also plans on buying an AC welding machine. para sa repairs on agri machinery later on.

    powercraft 300 sa tools from us sa cubao ay 4.9k ata nung last time na tanong ko. pero aluminum yun na 20% duty rating at full amps. compared to 40% na mga copper. kaso walang powercraft na copper dun. cheaper yung mga yamato portable by about 1k, inquire ka kay industrial supply. may discount ka pa.

        mas maganda dc na 200a in my opinion compared to ac na 300a, based on my own experience i own yamato 200a dc welder, and so far, kahit walang putol-putol na gamit hindi po ito nag-overload kahit walang tigil ang isang stick in full load na 200a

            no offense meant pero nagamit mo din ba yung 300a version? kasi kung hindi, baka ma-mislead yung TS kung sasabihin mo na mas ok yung 200a kesa sa 300a kahit wala ka experience na magamit yung 300a.

              Bro, as far as I know you can source or get your DC inverter from Industrialsupply 143 in Quezon City, headed by Joseph S. who by the way also a member of this forum. You may also consider GOLDPEAK Tools & Hardware, headed by Heric Martinez ( coolmaxheric ), also a member of this forum.

              May I suggest considering the 300 amp DC Inverter Yamato for I believe its a better choice than the 200 amp DC welder. They are both selling the welder at the same price but the former source can give discounts to PHM members. I have nothing against the 200 amp DC welder which I have been using for the past years but decided I wanted a more powerful welder so I got myself a 300 amp DC Inverter , only its a different brand which they didn't have yet one before. And I have been fully satisfied with its performance for more than a year now, also its much much better than my other 300 amp AC welder.



              Hope this helps !!

                sir fourtheboys96 nakatry na po ako gumamit ng AC 300A na welder pero DC 300A hindi pa po

                sir pakibasa po ang post ni migueltyler he is comparing AC 300A to DC 200A, kaya nagcomment ako na mas maganda ang DC 200A na ito

                sir fourtheboys96, sa tingin ko po migueltyler was not comparing DC 300A vs DC 200A so paano mo po masabi na mamislead si migueltyler?

                  Good day! I'm just helping my father to choose what welding machine to buy.
                  Can someone please tell the difference between 300 AMP DC and 300 AMP AC, and which is better for heavy duty and not., and if there's portable of this kind?
                  How much does it usually cost and can you also please recommend a trusted seller? Around Manila/Caloocan area.

                  Thanks in advance and God bless.

                    For prices, visit this site
                    https://goldapextools.com/collections/welding-machine

                    (I not in anyway connected with gold apex /gold peak but I visit their website to check for prices)

                    If you click on the link, you can find a portable version of 300A welding machine.
                    **Choose copper coil over aluminum
                    **The higher the duty cycle the better (ex. 40% duty cycle means 4 minutes of welding, 6 minutes rest)

                    I only have an AC welder but from what I read DC is easier to use.

                      I own both, a 300 amp Yamato AC machine and a 300 amp HiTronic DC Inverter machine.
                      Both are heavy duty welding machines that can take any punishment thrown at them in terms of usage.

                      The AC machine is really heavy and bulky, yes they have caster wheels but I find them too small for the unit that is why its hard to move around. In terms of pricing, its a lot cheaper and fairly affordable. A unit of this 300 amp are priced from 6,500K up to 10K, beyond that sobrang mahal na.
                      Usage, it can take any size and type of welding rod, 6013, 6010, 6011, 7018, 7024 etc.
                      For electrical connection, provide a real heavy duty plug and socket and a breaker for it or you can just tap the wiring to your fuse box of 60 amps.
                      The machine has a loud buzzing sound during welding.

                      The DC machine is lighter and more portable unit, you can easily carry it anywhere you need to do some welding. DC machines are a bit more expensive, from 12K to 16K or more for the branded machine like mine. For usage, soft start, easy to use and can also take different size and type of welding rods. This can be plugged in an ordinary household outlet and has minimal buzzing sound
                      when welding. DC units require some duty cycle, the 60% duty cycle is the best preferred one.

                      Dragon Prime Enterprises is the importer of this brand, just look for Joseph.
                      They give warranties and the service center of their Yamato brand, etc.

                      Just look for Heric (coolmaxheric), he is also a member of this forum.
                      This is where I purchased my HiTronic DC Inverter machine.
