More than a thousand when you add in two euro torches (mig and tig).
You get a MIG able to weld continuously at 110 Amps and in bursts up
to 160A. A stick welder with the smoothness of an inverter supply and
rated at 140A peak 100A continuous and a TIG (for aluminium or ss)
140A peak 100A continuous. All in a package that weighs only 12kg.
With conventional copper coil and iron core machines each would weigh
more than this and each would be designed for only the electrical
characteristic for the type of welding (MIG has very low open circuit
Volts stick has a higher open circuit Volts but then drops as the arc
is struck IIRC). This device looks like it handles the characteristic
electronically with semiconductors and little or small hf
transformers.
So for someone that has to travel to fabricate things on site it would
pay quite quickly.
I was on a site a couple of weeks ago where a 16 gauge pneumatic duct
had to be shortened (mig), a channel section had to be welded in to an
auger (stick inverter) and a ss pipe leaked water at a bend (could be
done wit tig but we cut the section out and replaced with copper and
compression joints).
I couldn't justify the expense as I have stick, mig and Oxy Acetylene
which covers most things but the wire feed on the mig, which I rescued
from a skip and grafted a new euro torch onto, drives me to
distraction. I'd love to try a "professional" model just to see how
good the wire feed may be.
