Mogli,

You must give every bit of information possible.

What were the Amps? What was the Gas Flow? What is the Electrode Size? What type of Electrode? What is the material thickness? What type of shielding gas? How much stickout? Etc Etc.

What model is the welder?

Also, could you have a gas leak?
