Welding mats protect you from injury associated with heat, electricity and fire caused by welding. These mats can withstand up to 1500 degrees and 30,000.
All matshop welding mats conform to Australia Standards AS/NZS 2978:1995.
Depending on your needs, you might want a welding mat that doubles as an anti fatigue mat. These have both properties so you don't need to use two mats at once!
