SPOT WELDER TONGS

I have 110v hand held spot welder that i bought at harbor freight. It works great. I love it. Ive used it on many quarter installs. The only pinch welds i cant use it on are the wheel wells. Ive seen pictures of the type of tongs i need but cant find anyone who sells them. Anyone know where i cant buy a pair or someone who can make me a pair of tongs like i need ?
