welder help

[stanmondz]

i got a lincoln sp135 plus.
it dont feed worth a crap, i pulled the cable out of the stinger and it had a slight kink in it.
is it possible to get the kink out without screwing it up worse?

a new stinger assembly is 200 bucks, this is a 135 dollar pawn shop welder

what size wire?

A new tip, feed roller, and liner will make it like new. Have you tried tightening the roller? try keeping the cable as straight as possible. Post a pic of your machine with the door open

 

[stanmondz]

.035 wire.
there looks like a piece of wire broke off in the kink

where can i get a liner from? all i can find is the whole assembly

Here are lincolns part numbers for the liners for your machine:
Liner .023" - .030" part# M16291-2 Part Discontinued – USE KP1937-2
Liner .030" - .035" part# M16291-6 Part Discontinued – USE KP1937-3
Liner .035" - .045" part# M16291-1 Part Discontinued – USE KP1937-1

For small stuff like rc cars I would suggest going with the first one for .023"-.030" new part# KP1937-2

Ebay listing $9.95 + $5.95 shipping

I would suggest an .030" tip, .030" wire and gas shield

The sp135 is actually best run with a .023 wire and 75/25 (argon & CO2) mix. The larger wire causes the machine to reach its duty cycle faster. Higher the wire the higher the amperage causing the machine to run hot. The gun is more than likely made by tweco. A good liner from a welding supply is about $25 and don't over tighten the feed roller tensioner. The rollers are also marked and make sure those are correct for your wire size.

got my liner today
welder runs much better now.running flux core wire. i dont have a bottle or regulator for gas

 

[doublej]

get a bottle and reg for the gas upgrade and you will feel like your using a new machine all over again.

 

[stanmondz]

what makes gas better than flux core? i have about 2 hours experience running a wire welder
