I borrowed a Miller Suitcase welder from work to try and use it for some of the body work on my 53 Dodge Truck- floor panels cab corners. This thing has got me beat. Welds like crap. Problem is no one at work remembers using it. The last guy that used it can not remember the setup for it. I downloaded the ownwers manual and it is not much help. I need to be sure I have it set up right and the correct settings such as the CC switch. Does it run on positive or negative DC. I got it to weld but I do not like the results. I got the right gas mix, set it up like the welders at work use on their machines. I feel good about the gas mix 80-20 and flow. Problem is I can not get a repeat good weld. Tons of splatter. I am using clean new 16 gauge metal , .035 wire alredy installed. New tips, It is hooked up to a Lincoln 225 AC/DC Welder. I have no idea where to set the amps on the Lincoln or the wire speed on the miller. I am almost ready to take the Suitcase back to work. The Suitcase is like new, may have been used one time. If you can direct me to proper setup maybe I can get it to work with pratcice. Note: I was a amature welder but know what a decent weld looks like due to being exposed to an industry that has alot welding application-mostly 7018 welding applications. Seems we weld almost everthing with 7018`s. Anyway Help !!
