Really good fine adjustment of voltage & feed speed when you make a fine adjustment to the voltage it can be seen in the weld making it easy to get you're settings perfect.

I Brought the Weldclass 255 MST for at home projects, and wanted to buy the largest amperage 240 Volt Machine I on the market. Originally when I brought it there was an issue with the internal gas plumbing but I rang the Weldclass distributor at Tamworth and Tony was very friendly and fixed the issue quickly for me. Just an internal clamp that was loose. Since then I’ve used it a number of times. I love the build quality of the machine, It’s very heavy and durable, seems like all the internal components look very well engineered. I like how easy it is program for the type of Mig Welding that you are doing and takes the guess work out. The welding gun is also very heavy and durable. Love the product Jamie

Comments: Coming from a old school Mig, the machine with the computer control of weld via the synergic settings is taking some getting used to. I feel like just using program 0 so that I can set up as per original tech, but am persevering with the other setups. General quality seems to be good, but haven't used it much so can't say about longevity etc. The wire feed seems to be good quality and robust and was a factor that I considered in the purchase of the unit. The setting of the unit to restrict the machine to 200 A is a good feature, but perhaps it should be set on by default, as my machine powered up with the full 250A capacity and although I do have a 32 A feed, the supplied lead is only certified for 15A afaik.
