Welding shops are very common in the Philippines. It seems like ever little corner has a welding shop. Most of the vulcanizing shops has offers welding jobs too. When we constructed our parents' house few years ago, we had to get a permit from the electric company for us to do some welding jobs. The electric company has to put a transformer to the nearest electric post to avoid shortage.
Anyway, I remember that the construction people that work in our house didn't wear office helmets for welding. They had a shield to protect their eyes but not really the required helmets. Upon reading around, I realized that welders should wear the proper helmets for their safety.
