idahofj,

That's a hard question to answer. I think that roll cages should be taken very seriously as a possibly life saving piece of equipment. A very experienced and skilled mig weldor could probably do a good job of welding together a rollcage with that welder, but I think any other weldor would be well advised to use more welding current than the 135 class welders can supply to assure strong reliable joints.

Welds can be deceiving. One that looks good - continuous, smooth, and right can be porous and lack enough penetration to keep it from cracking or breaking loose under stress. It can surprise a good weldor and is the reason for weld inspections of several types.
