Make one bench then use that as the jig frame..i.e fabricate all the others on it upside down
Use lots of anti-spatter..

Grahame,

You made a point that lay people do not have the experience.. so true.. which brings me to my point that most lay people will not be tackling heavy fabrication jobs. At best they may weld...

I disagree with the 180 amp figure.. all depends on what you plan to do. I have found for most home projects, business and construction worksites my 170 has been perfect, be it for mild steel,...

I wouldn't buy less than a 150 amp... As most home welders rarely work with steel more than 6mm thick a 165 to 200 is ideal. I prefer Lincoln or WIA as brands like SIP have many plastic components...

"I owned one of their 250 amp industial ones for a while" ...a workshop welder on wheels that doesn't get knocked around as much as opposed to a portable machine....still "probably 75% as good "...

Most of us have been exposed to asbestos sometime in our life ...to get it professionally removed is very costly and can involve a lot of red tape..if someone says don't worry about it or don't care...

For 12mm stainless they most definitely would have used a mig clinton1...given the size u described they probably dogged it down and utilised sequence welding. With the right grinder discs etc...

Hi Andymac.....yep I use gasless...did the figures and working daily it adds @ $20 a month but u save on time replacing empty gas bottles and of course never run out of gas on a day u can't get it. ...

Try using two pipes set at appropiate distance and heights, a pronged attachment that fits in the spool spokes on a variable speed drill, elbow/forearm as feeder spool tensioner and a paddle to...

PS. Gasless is cheaper for the hobbyist...no bottle hire or running around for a refill! If you ran the welder 4 hrs a day five days a week, flux core would probably cost you an extra $40 a month/$2...

there is no such thing as a good cheap welder. Cheap welders have plastic parts and thin motherboards meaning they are more likely to break down and cost as much to repair.
i own a Lincoln 170t MIG,...
