Hobart cyber tig 300 ac dc

As Shenion said, really need a shot of the whole white panel to label things properly but if you download and read the Miller TIG handbook that was mentioned a while ago, it explains what slope controls, post flow etc are. There are NO standard settings for most of them, depends on the job (material, section thickness, welding speed, personal preference etc.etc.), especially when dealing with pulsed TIG. You have to experiment learning the effects they make as you go, settings i use on my machine don't directly translate if i use someone elses- always need to set it up with some scrap until i've got a feel for the plant

Preflow ('pre purge' on your pics) is about the only parameter that can be set and forgoten about (1 sec will cover you for most materials)

Many of the parameters are discussed in more detail in this thread. At best it's only a starting point though

You really would be better off passing on that mag job, especially if it's welding on a chainsaw case! List price of mag filler FWIW, expect to pay at least 60% of those prices although i would be VERY happy if someone says i'm talking nonsense and they're available for much less £££

Set it to 'DC straight' and have a play on some mild steel. Switch the pulse OFF, follow the miller guide for postflow settings, amperage and tungsten and get a feel for torch and filler control.

your probably right it may be best to practise on mild steel .

A large picture of the white area might be more useful than each control on its own.

hi hers photos of the panel

Well i've tried but may be off as the pic is blurry. Cleaning the panel would help too. I think i've got most of 'em by using the previous pics and 3 windows!



1. preflow time. Time that gas flows before arc is initiated to purge the torch lines and weld zone
2. hot start. Self explainitory, more related to MMA than TIG
3. inital current. More common with TIG to strike up below main welding current and...
4. 'slope up' over a some time (a sec or so) to main welding current
5. delay timer for pulsed TIG. preheats the work before pulsing the arc
6. Downslope. Smoothly reduces the current at the end of a weld to the...
7. Crater current which helps prevent leaving craters in the end of the weld
8. Post flow. Argon continues to flow to protect the hot tungsten (and weld) from oxidising.

The pulse settings will cover peak and background amps and times for each or a frequency adjustment. Can't tell from the pics. Search the forum for 'pulse' there's several threads that go into quite a bit of detail. Things like initial and crater current are set as a percentage of main welding amps, slope up and down, pre/post purge etc are in secs

The other switches i've not labelled are either self explainitary or illegible. The dials underneath those i've labelled look to be timers for spot welding etc
