little TIG inverters @ 230V single phase

By Scott_V Date 06-27-2004 19:37

Uhm,
Went through a lot of work researching this so wanted to put it in an on-line archive. Just a list of current draws and outputs in TIG mode and using 230V single phase for the lightweight inverter welders that I'm considering. Figure there are others with 30amp circuits that can use the info:

Miller Dynasty 200 DX 45lbs (also 3 phase capable and 115V single phase capable)
150amps 16V 60%duty 230_single_phase 15.8amps-in
max draw - same as above

Lincoln Invertec V205-T 38lbs (also single phase 115V capaple)
170amps 16V 60%duty 230_single_phase 18amps-in
max draw - 30amp_in@200amps_out 18V

Thermal Arc 185TSW 42lbs (230 single phase only)
130amps 15V 60%duty 230_single_phase ? amps_in
max draw - 38amps_in@185amps_out 17.4V

heres two more choices

Always check the watts. Watts are volts x amps. Watts are also where the work is done. Watts are heat, very important in welding ;-)

That said-the major manufacturers went through a marketing thing a while back.

They would lower voltage slightly, or not slightly, to increase amp rating, duty cycle, etc. It was basically a marketing thing-no, it was definitely a marketing thing.

Buyer be aware-do your homework!!

Any questions-email me direct.

Good Luck

I used to be Scott V myself but it looks like there is another one out there. It's ok though because the second one seems much brighter.

My friend Aaron had the Thermal 185 and he was drawing less then 30 amps at 199 amps output.

I found a site comparing welders and it listed the 185tsw only pulling 30 amps at full output, but the owners manual says 38 amps.

That's good news for me because I ordered a 185tsw and was worrying about tripping circuit breakers.

I used to be ScottV but that was already taken.
You're right he does seem brighter :-)
(the first one, that is)

I know you're trying to summarize some info., but your first and last notes I checked for the dynasty 200dx are incorrect. I didn't check the other welders. You have stated that the max wattage output for the welder is 2400watts, which is incorrect. I suspect you derived this from the 150amps,16volt tig spec on single phase 230vac. The unit easily runs to 200amps on single phase and the output voltage can be extrapolated from the other data points (y=mx+b linear equation). I'm not going to take the time to look at the other values, but just thought you might want to recheck your specs. Also, your first post indicating the single phase MAX draw is 15.8amps for the dynasty 200, is also incorrect. 15.8 amps is the draw for 150amps,16volts. If you increase the amperage to 200amps for tig, the input is likely to be about 22-23amps. Stick welding will draw higher input amperages as well.
