lincoln 180T vs. 180C

admin

i've been doing some research lately for a welder and i've decided on either the 180T or 180C.  the only difference that i can see between them is the voltage control; the C has infinite control.  the list prices are relatively close but i think i can get a T for about $200 cheaper than a C on ebay.my question, is the infinite voltage control worth the extra money or will the voltage settings on the T be sufficient?  i plan to use the welder for autobody, suspension, exhaust, and light fabrication.any advice is appreciated.
Reply:I can work with a Tapped welder.   A continuous  voltage welder works with you.  If you are doing the finer stuff, Taps are a pain in the butt.  Spend the extra then you won't be cursing your machine later.DavidReal world weldin.  When I grow up I want to be a tig weldor.
Reply:I have the 180c.  I like it.  I have had three mig welder and all were infinitely adjustable.  I have always been afraid I would not e satisfied withe a tapped machine.I got the sg 100 spool gun, too.  Are the tapped machines spool gun ready?  If you decide to do some aluminum them would continuous or tapped be better?
Reply:All the new Lincoln small MIG units (180T and 180C, and 140T and 140C) are ready and compatible with the SG100 spool gun.The capabilities on the machines are the same for tapped versus continous, no real difference on the MAX or MIN settings.  But the continous lets you dial in the parameters a little bit finer than you can on the tapped units.  And, you can change the voltage while welding with the continous units.  With the tapped units, you have to stop the arc and then change the voltage setting, and then restart the arc and see if you are better or worse with the new setting.Just starting out?  A tapped unit will be OK (less knob fiddling).  Once you get some practice and experience and a few clues, when you can notice a voltage change of 1/2 to 1 V in the weld/arc behaviour, then the continous voltage control is much nicer.I like the way David R said it.  You can work -with- a tapped unit, but the continous control unit works with you.  YMMV.note, some tapped machines with a few more tap settings let you get a bit closer in your parameters than machines with fewer tap settings.  But the continuous control units still let you fine-tune a bit more.
