What a difference a liner makes!
I've been playing around with an old SIP Migmate 130 mostly to try and understand why people have so much trouble with them. The wire speed had been quite unstable, and you could see the end of the wire moving up and down while it stuttered along.
Changed the plastic liner for a new steel one this morning and replaced the spring like guide inside the swan neck that had become clogged up with the old liner. Now the end of the wire is completely steady.
I measured the force needed to pull the wire through the torch with the rollers untensioned. With the old liner it took 33N to pull the wire through, and the new one 6N.
Much more controllable on thin metal now. Just wish I'd replaced the liner on my old welder more often now - would have been sweet, but instead struggled on for years on the original .
