I am considering the purchase of a laser welder. I don't have any
experience with them and would appreciate owners and users of
lasers to share their good and bad experiences...I would also like
to compare the mini arc 111 to a laser. I am just an ole torchman
who would like to move into the modern age if practical...
Being also an "ole torchman" like yourself, here are my two cents:
FIRST: One year ago or so we bought a PUK II, the upgraded version
of the PUK 111. The idea was to save the big investment with similar
results of a laser welder. Well, the PUK II is indeed a great little
machine: very well built, reliable, and after several hours
experiencing welding you begin to get some practical results, I mean,
you are able to weld pieces and find solutions that would not be
possible with the torch.
Some considerations: It costs around 15% of the price of a laser,
what is apparently good. You save time welding, but it takes you a
lot of time to keep the needles sharp enough to make the welding
possible - at each other 10 to 15 shots you need to stop, get a new
sharp needle or sharpen it. The oxidization around the welding area
is considerable, and it takes you another considerable time to clean
it. You will find that the welding is not too deep, what makes
soldering sometimes a more appropriate approach. You must use argon
gas, and it must be a very clean one, otherwise the oxidization is
But, after all, the machine works, and it is indeed a reasonable
alternative to the laser welder.
SECOND: About five months ago, we bought a laser welder. I will
resume everything you may have heard about it in just one example: I
don't remember the last time I used the torch to solder something!
My piece of advise: If you can afford, use the $4000 you would spend
with the PUK as down payment for your new Laser welder.
Good luck, and please forgive the bad English
