I have a Lincoln SP175+ MIG. The gun that comes on it is crappy. I've had
it apart a half a dozen times, fooling with the contactor points in there,
which amount to a tiny washer, a spring, and two wires with crimps on the
ends.
The gun has some life in it. Rather than just junking it and spending $100
or more for a new one, couldn't I just go get a decent pushbutton and wire
it to the outside of the handle in the most comfortable position, and
rerouting the wires? It's just a shunt from the relay. When it's welding,
it's a joy, but when it goes in 2,5, and 10 second spluts, it's a pain.
I need to get this running, and running like it's supposed to because I have
a project to do. $100 would buy some materials, and if I can fix it with a
$5 switch, that would be fine with me.
I don't know why Lincoln would put such a piece of crap on one of their
welding machines.

Shouldn't be that hard. I replaced the switch on my Century with a
standard micro-switch. MUCH better now. I milled a small plastic block
to hold the switch and with the block it fit directly in place of the
original switch.

I futzed with the switch a while back, and I thought I had it working good.
But it just gets in a certain position, and it goes off and on. Nothing
that is good for a good consistent weld. Was thinking of buying another
gun, then thought of just getting a new switch. Will go shopping and see
what's available. There's just two wires. As you say, making a block or
something to hold the switch is the work of it.

One thing I don't have to look for, probably have 50 on hand. Plus
assorted membrane types and various others.
Hit any of the surplus outfits and you will find lots of them.

I think I just want something substantial that will hold up to
dingleberries. I think I will have to handle the handle ergonomically to
see just where I end up putting the switch. I think a button type would be
best, and anything with a membrane would get smoked in ten minutes.
