Hi Guys,
I've built a few chromoly bikes over the last two years.
To date, I've been using no pulse, just a foot pedal to control the current.
This is my machine: AC DC Pulse Tig Welder Plasma Cutter 200 + 40 Amps - Tokentools Alusync200
No, it's not a high-end machine, but it's affordable, and the company has excellent customer service.
I'm now starting to dabble in pulsing (around 1.5pps, 40% peak), but I'm not sure if my welder is properly designed for this.
It definitely has pulse functionality, but when welding with pulse, the foot pedal actually varies the backround current, rather than the peak current.
I've tried running the background current higher than the peak, but then the machine only puts out the background current.
I'm having difficulty feeling comfortable with this pulse behaviour, since I'm unable to control the peak current.
Shouldn't the foot pedal vary the peak current, rather than the background current?
I'm thinking about adding another foot pedal, connected in series with the existing pulse current knob on the front of the machine.
But then I started wondering whether other machines offer a different means of controlling pulse welding via the foot pedal.
I.e. Would there be any advantage in being able to control the duty via the footpedal, rather than the peak current?
Thanks,
Hugh.
