Tig welding machine Q

admin

Aloha from Hawaii welding forum. Hope this is the right place for this.I am a boat captain but do alot of repair and fabrication (you have to have like 3 jobs here lol). I got offered some work fixing aluminum and stainless on our fleet as well as a chef friend doing all the kitchen repair for his resteraunts. So I was using a friends welder just here and there but now I want to buy my own. I have welded tig on and off for 8 years. I am only doing mobile TIG work but maybe it could grow later on into something.So as not to break the bank in the beginning I was looking at the powerTig 250ex and 200DV.I like that I could use the 120 or 240v with the 200 but the 250 seems like a way better machine. I know I have 240v at the harbor and it seems like it would be easy at the kitchens but I am just looking for suggestions on practicality. This is kind of a test the waters thing. The one gig will pay for the welder set up so if its not a growing marketplace for me then I have a new toy for my shop lol but I really would like to try and start a small business that could grow. There are a ton of stainless kitchens in this restraunt mecca and a weak work ethic so I think I could do ok.Thanks for your help.PS got a ton of grinders and hand tools but will definetly need more clamps and portable bandsaw (I have a tool addiction. I have 10 handplanes for shaping surfboards that do the same thing lol )
Reply:As you want to do a lot of stainless, be sure to get high speed pulse.    The machine you mentioned has it.Tiger Sales:  AHP Distributor    www.tigersalesco.comAHP200x; AHP 160ST; MM350P,  Spoolmatic 30A; Everlast PowerTig 185; Thermal Dynamics 60i plasma.  For Sale:  Cobra Mig 250 w/ Push-pull gun.  Lincoln Wirematic 250
Reply:My Dynasty 280DX is 52 lbs. goes to 280 amps, (I often use it all on aluminum), has pulse, multiple ways to automate, can be upgraded to give amplitude. It uses 37 amps at 230 volts. If you do on site work you want a little tank, or a good cart to move a big one. You want both air, and water cooled torches.An optimist is usually wrong, and when the unexpected happens is unprepared. A pessimist is usually right, when wrong, is delighted, and well prepared.

Reply:I know there is alot of hate on these chinese machines. I can afford them now and can upgrade later. It is very exspensive here I am just trying to get by. So if anyone has any suggestions on if dual voltage is enough of a adv to sacrifice power I would love to hear your opinion. Thanks again!
Reply:There is no escaping that wattage is required to melt metal. To use 120 volts, you double the amperage. Broccoli makes the point that you could build a 100 amp 120 volt circuit. That isn't what they are doing with 120 volt welders. You should be installing a dedicated circuit. It costs less to get 6000 watts 240 volts, than 120 volts.An optimist is usually wrong, and when the unexpected happens is unprepared.
