Migatronic are struggling, talk in the welding industry is that they may drop thier warranty from 2 to 1 year. They have had good market share during the 1990's but have lost a lot of business for many reasons over the last 5 yrs.
Electronics (pcb's etc) are manufactured in Migatrinics own modules and are not easy to repair but are available service exchange from Migatronic- At a hefty price though !
