Hi
Re SWP Invert R 180p Tig Welder DC Tig and MMA
I have just got my small Tig out to test it and the gas solenoid does not seem to be functioning. It works on MMA.
Does anyone know if there is a parts list out in web land so I can locate a spare? Also is it possible to free them if they are...
Hi I Have an old but still working cutter as above but it does not have any power adjustment - just on and off with fuses on the front panel. It is a large transformer machine although single phase 220v. Does anyone have experience of these machines or similar? How is the power adjusted? Can run...
Thanks for this. Yes I went over every component and both sides of the circuit boards - no sign of a burn anywhere. It has two RIFA capacitors in blue plastic cases which seemed fine. As I said the only issue seemed to be an issue with the switch which, it seems, only has a 1000 operations...
So opened it up, cleaned it out and checked the four 470uf / 400v Epcos 30 x 50mm caps. Three had swollen patches but no burns. The switch seemed a little stiff. So replaced the switch. Now if I switch on the welder then the MCB and then RCD it does not trip. So some progress. No other evidence...
Thanks for the replies. My clamp meter covers M ohms so I carried out various test but little obvious re leaking to earth. As you said it may be that the meter does not respond quick enough. Will check for leakage when powered up.
Hi
In have various welders and cutters up to 220amp - most of which are of standard transformer design. I am a bit of a welder collector of all types. In my workshop I have a dedicated supply for the welders etc via two commando plugs, 16amp and 32amp, with MCBs for each plug and a 30mA RCD...
Hi
I have just picked up a Pearl XL 180 which has a push fit gas supply fitting. I don't seem to be able to find a regulator to welder hose for this machine. I think the external hose diameter size is 9mm and it is to be connected to a standard 3/8 gauge thread on my gas bottle.
Anyone know of...
Thanks - the transformer is smaller than in my Cebora 190 and my Tec Arc 220 tig. So the quality of the welding is governed ultimately by electronic wizardry on the PCB in conjunction with the transformer. I will check all joints the terminals, clean them and then run fresh 1mm wire through and...
Posted this is the wrong section originally so I have moved it to here.....
Hi
I have a Oerlikon Mig Citoline 2500M which is a great bit of kit except the welding at the higher settings ( it has 12) it seems unstable and almost 'flares' during the welding process. At lower settings it seems fine...
Thanks for the replies - been emailing Les at TecArc and it seems that my machine built in 2010 is only a 400V machine although the label on the machine shows 400V 20amp and 230V 32amp in the supply box. I must have mis-understood the label when I bought the machine or it was a mistake as it...
Thanks guys - I actually have a 3 phase meter which is only tapped with the Red and Yellow lives. Yellow supplies one side of the house and red the other. There are two main fuses for each phase, both supplies use a common neutral. So as long as I take one live from the red phase and the other...
Hi
I have a 400V welder which I only use occasionally and I have brought to my home workshop. As with most so called 3 phase welders it only uses L1 and L2 + Earth as transformers at 400V do not need L3 and L1 and L2 don't need a neutral as being out of phase with each other they act as each...
I have a TecTig 222 AC/DC tig welder which is a dual voltage machine but which is currently set up for 400v 3 phase and I want to know how to set it up for 220V 32A supply that I have in my new workshop. I cannot find the manual and would welcome any advice as to how to do this (and also a copy...
Thanks Mike - My wiring is almost the same as this although the components are laid out slightly differently. A separate rocker switch would be a simple solution - I understand that the condenser was only to smooth the arc at lower voltages for sheet metal work.
Really helpful reply. It is great...
Hi
I am fitting a new 6 position rotary voltage switch on my old Cebora machine. I understand wiring mains to transformer except I don't see how the smoothing condenser is wired into the switch - wires C and 6 which are white in the machine and joined with a cable tie.
Has anyone got experience...
