Chinese inverter welder

Recommended Posts

I've got a javac 170amp inverter arc welder which was quite expensive when I bought it about 10 years ago and I've never really got on with it the duty cycle isn't great and it's very rod fussy. So looking on eBay for a replacement I noticed several 200amp inverters for amazing prices. The cheapest was £48.99 or make an offer so I offered £45 and it turned up in three days. On opening the box it looked like a toy it weighs about 4kgs and is tiny. After fitting a plug and using the leads off my other welder (the ones supplied are rubbish) I fired it up and amazingly it worked I ran 10 X 3.2 rods in a row and it never cut out so I turned it up to full and ran a couple of 4mm rods and it still didn't cut out. It welds very well I don't suppose it will last very long but for £45 it's amazing.

hello, they are  great tools for welding,  did it come from china or a uk seller but chinese made?  my little welder like that cost £100 and its been good so far after 3 years use, considering i got the farm a decent one made in UK cost £400 about the same time, 180amp, good luck with yours,

It must have come from a UK supplier as it only took three days. But a Chinese company is listed as the seller so I guess they have a warehouse over here.

How can they make a welder for that price? Transportation costs profits for maker and seller, it don't add up. But they do and I have seen some you tube videos of reviews and even pros are surprised by some.

 

I would like a tig inverter with hf but knowing which are ok and what to avoid is difficult.

try and get a 2nd hand Fronius...........

I know where there's one of them, I tried to borrow it from my old man but he's having none of it, to be fair he rarely gets anything back that I borrow, so I bought a cheap one from aldi of all places for £25, I can ask if anyone is interested

If you are only doing a small amount of welding (one rod a year) then probably one of those **** Chinese things will do get yourself one made in England it will last for years. 

Well it's already done one 5kg pack of oerlikon 3.2mm and several 4mm and still going.

Neighbour of mine showed up on the doorstep backalong proudly carrying an ALDI bought Parkside 130amp inverter stick and asked for some lessons, I'll admit to a little snobbery when he unboxed it, at £70 with leads, auto darkening helmet, chipping hammer and a small pack of rods how good could it be. Well for a start it comes with a 3 year money back or like for like guarantee. No need to post off and register like some of the trade names just rock  up to your local store with the receipt, so in theory you can't loose. We ran all the 2.5mm 6013 rods it came with pretty much non stop, partly as he was keen to learn but mostly to see how long before it overheated or popped. It ran fine so we moved up to some  3.2mm 7018 that I had in the van. He didn't like them but the welder never even faltered. For that £70 you could nearly call it a disposable welder on a site job and for DIY around the house I don't think you could go wrong.

hello, depends on what size rod and amps of your welder and what you are welding? pre heating might help, 

it's garden furniture so not the best quality iron, I haven't got any iron rod yet so don't know the core size, I think the amps run upto 120A, i'll have a look about for the rods, might be able to get some slim ones, cheers for the reply.

hello, you can get rods that requires no pre heating come in 2.5 which should work up to 120 amp, best do a few test runs

do you guys reckon these cheap welder would work ok with cast iron rods?

 

check first..........some of these "not normal" rods like cast iron....high deposition rods etc....prefer a DC welder as sometimes it is recommended to weld negative electrode..... positive earth.............check the writing on the box first before you buy...

Thought arc welders were DC output and you could just swap the cables round to change polarity.

welders are a/c or d/c...................with a d/c welder if you are welding positive electrode...2/3rds of the heat is in your rod....if you weld negative electrode 1/3rd is in your rod

thats why when you are using lo-hy rods 2.5mm on a root run you always burn at negative electrode.........some coatings on the rods are designed for the polarity....it will advise you on the box..........

if you are using DC then you can do anything.........................the new...(newish) inverters Fronius........are superb........i have one that will do MMA and TIG and you can alter the force and ocv and all sorts of things.................they are good but bloody expensive........

I remember back when I worked in the foundry we had a big old oil cooled DC welder, I spent weeks weld filling cast iron panels for the albert memorial thingmajig.

for some reason I thought inverter welders were DC

i'll go through the destructions of my little £25 aldi bargain this weekend, do need a face mask though, so probably shopping first

cheers for your help gents
