Just bought a tweco spray master 400 A mig welding assembly. Still has the original tip in it. The guy didn't like it, so he bought another brand. He 'thought' he paid over 100.00 for it and I agreed that he probably did pay more than that...what do you want for it. He replied " you can have that and all these tips and the gas diffuser and guard for 20.00." I had the money out before the period ended his sentence.
