hello gentlemen users of this prestigious forum, finally for my birthday, I bought a new welder inverter three phase 220 v this is an MMA Welding Machine 

max. 180 A | PFC SOON 

Inverter welding with coated electrodes. 

These models are extremely robust and reliable. Particularly simple to 

use thanks to features Hot start, Arc force and anti 

bonding. Weld rutile, basic, stainless and special electrodes. 

They can also be used for TIG welding with scratch striking. 

They have to set the DIGITAL DISPLAY, the socket for remote control and 

VRD function which makes it suitable for working in hazardous environments. think someone has made ​​a good choice among you use it as it is,? that recommendations and opinions you can give me? I await answers thanks excuse my insistence and petulance

Congratulations on the new welder. I think Google translate might not be the way to go on writing your titles. Or at least maybe make em only a few words long?

Photos of the machine, Photos of the name plate, are needed to get a helpful response.

 

Foto della macchina, Foto della targa, sono necessari per ottenere una risposta utile.

okay I will let you know next week I begin to use it I have to weld beams 160 mm, I made a good buy? I took basic electrodes of 2.5 mm and 3.5 mm, the welding machine is single phase. the current contract has a power of 3.5 kw, do you think it is sufficient to achieve good soldering resistant? thanks to the next

Some meanings are lost in translation.  By "good soldering resistant" do you mean "good penetration" of the base material or something else?

Your questions are so basic that they indicate a lack of knowledge needed to safely build this structure.

1. Weld two pieces of the stock you are building this thing from together. they can be small, 75mmx75mmx thickness of box beam wall.

2. vee both ends to be joined, 

3. Weld the two together with as many welds as needed to rise above the surface of both sides. 

4. Put one end of test piece in a vise after welding. with the weld not locked into the vise.

5. Use a 1.5-2 kilogram hammer boldly strike the protruding test piece until it breaks off or bends. If it bends, bend it a full 90 degrees. 

6. If it bends all the way, with NO CRACKS WHATSOEVER then your system is usable for your task. 

7. If not, make all your pieces, clamp them together and call a professional welder to fuse them together for you. 

 

We, as a group of artisans cannot construct unsafe devices which risk the health and safety of the public.
