2. INTRODUCTION & DESCRIPTION
These instructions are to assist you prepare your mig set for welding together with information on maintenance, and trouble shooting. Read this
manual carefully in order to get the best results from your welding set. The instructions are not intended to show you how to be an expert welder.
It is with continued practice that you will achieve the desired results. Mig welding requires a steady hand, time spent practising with scrap metal
will gain rewards when you progress to an actual workpiece.
Supermig 250/10 is a compact power source fitted with a heavy duty wire feed motor. The wire feed system itself is automatic thus providing
the best possible opportunity to achieve the most effective weld. The machine operates on a forced air cooling system to slow the transformer
heating in order to increase the duty cycle, and a non live torch to prevent the risk of accidentally striking an arc.
