I have just purchased a Millermatic 135 (in transit)for welding hollow metal door frames and related items to the commercial door business. The welder will be used both in the field and in the shop mostly for repair work on material between 12ga to 18ga. My experience with welding is at least twenty years ago with stick. I tried to read the threads on helmets but still a little confused. Solar vs battery (welder will not be used on a daily basis),large range of lighting conditions (poor light conditions on jobsite to well lighted shop), speed of auto darking, size of viewing area, etc. Like the rest of you, I do not like buying things twice. Any input is appreciated.
Thanks Dennis
