Unless you have actually seen an Optima pulse unit making the welds you want in the position you want, you may be spending a big chunk of change that won't much help.
Thanks for the heads up, we do alot of small piece work, spatter cleanup before plating is one of our cleanup nightmares, tried an Optima at a Miller open house thought it might help.
We have the Optima in stock. You can buy used for 625 or 850 for unit with factory warranty. If you will cover freight costs, we can figure a way to make sure unit solves your spatter problems or return in same condition. Email anytime. Thanks, weldersales
