Started playing with my new HF spot welder today. I've never used on before, and have a few questions.
Are the tips supposed to glow like cherries?
Is the main body supposed to get quite hot?
Is there a optimum trigger time chart for different gauges?
How often do you clean the tips?
Like I said, I've never used on before.
I did manage to get the intermediate supports installed.
I hope they hold!
Can't speak for HF ones in particular but in general yes the tips may glow, you are using them to apply enough electricity to heat metal to melting point.
The body may get hot over a period of time if you are doing a lot of spots.
You need to apply a firm pressure on the electrodes when you close them.
