Precision tig welders offer many advantages for a variety of applications
One precision TIG welder is the Lincoln Industrial K1826-1 Precision TIG 275
208/230/460/1/60. The Precision TIG 275 is the next wave of the Square Wave
family of machines. Its technology provides revolutionary arc performance ideal
for critical AC or DC welding in fabrication, aerospace, production, and
Available in both machine-only models or in a convenient Ready-To-Weld
Package, the Precision TIG 275 combines both outstanding value-added features,
with precision arc welding performance.
To make a long story short, it is essentially 2nd , very low amperage welder
that is in the output circuit. When very low output (when starting, or welding
at low current, or when tailing out the end of the weld ) is required , the
power is taken from this special "smaller" welder tailored for low amperage
performance. When higher output is required , the main circuits take over to
provide the output.
The start and low end performance is nice. What's important in the world of
TIG welders is low amperage performance. The torch hookup "pod" on the side of
the Precision TIG is nicer, and the unit does have a 30 amp advantage on the top
end. As far as water cooling goes , it's not so much as how much output you plan
to use , but rather the torch size you desire. An air cooled "17 style" is the
same size as a water cooled "20 " . The water cooled can handle 100 amps more.
Air or water cooled torches for precision TIG welders
You can purchase an air cooled torch that would be good for a 250 amp
precision tig, but it would be much larger than a water cooled version of a 200
amp torch. Water cooled torches run water in an annular jacket around the power
cable. As a result, water cooled torch cables are much smaller and more
Precision TIG welder coolers
Incidentally, the Cooler 40 water cooler in the Lincoln uses the same motor
/ pump assembly as Miller and Bernard coolers. The Lincoln unit slides in and
out for service and maintainance. The Miller unit cannot be removed from the
"TIG runner" undercarriage, so if you need service, the entire undercarriage
One note on the PFC capaciators: you will NOT save money on your power bill
with the kit. Buy them only if you don't have enough power to run the unit wide
open ( 94 amp draw on 230volts ). With the PFC , the unit will actually draw
more output at the low end and idle. Since the machine will spend the majority
of time at idle and low end you will actually consume more power. Another reason
to use the PFC caps is to reduce the PF shift that the utilitity companies can
penalize you for. This is not an issue if you only have the one machine in your
You save quite a bit of money buying the ready to weld water cooled package,
rather than buying the parts separately. Don't forget, you still need a foot
pedal, regulator , hoses etc. Once you add those in, the package is a good buy.
You work hard. You deserve the best tools. Consider the Precision TIG 185
for general fabrication, automotive/motorsports, vocational schools or the
serious hobbyist. Auto-Balance™ takes the guesswork out of optimizing cleaning
action versus penetration. Standard Pulse control makes it easy to gain greater
heat control on thin materials.
The Precision TIG 275
Patent-pending Micro-Start Technology provides unrivaled and revolutionary
arc performance ideal for critical AC or DC welding in fabrication, aerospace,
production, motorsports, and vocational applications. The Precision TIG 275
combines both outstanding value-added features, with precision arc performance
