A few more pics - the 120 and 240 single phase inverter welder from ESAB that is an upgrade to my older Thermal Arc; what we call suitcase or lunchbox welder. This one has digital display, a 60 series program setting, yes Tig too if ya need that; and Arc Force and Hot Start adjust. A little arc force helps with sticking 7018 rods restarts etc. The lift is the key to these "sloping grade" work assignments. Although there are offroad scissor lifts at the rental places, they neglect to provide them with the leveling legs - which is what I would probably search for if I had to replace this machine [hope not]. This Upright SL30SL (pls note: has to have that suffix SL) allows a lot of adjustment for grade - and - if the grade is planar without twist, one can operate the machine (relocate) while up in the air. Learned all of this from an equipment dealer - not from any of the local equipment yards. FYI: MEC has one but is bigger, and Snorkel has one but so far is only avail as diesel. This Upright is gas and LP, which LP could be utilized inside a warehouse. The grade climb ability is limited and needs help to mount a trailer (backhoe trailer requires a winch assist), but I usually have this low bed hauled with the reachlift which can give the lift a little boost onto the trailer, or they can provide winch assist. We always make shelves and for the lifts that we can remove or swap from side to side and will fit the various rental machines, keeps stuff from underfoot, folks are more productive.
