Welding Tips and Tricks

Hi guys

Seeking your input on this short video. This is me welding some square tubing frames with 0.8mm/ 0.032" E71T GS Cigweld Weldskill. The variables on this machine are minimal, a "synergically" adjusting setting that alters your volts and amps to suit.

From about 1:09 to 1:24 is the worst of it. Sorry for not showing the end result.

Any clues to this odd behaviour

Would not load the vid.

Ditto. No vid

Sorry about that guys. original link updated.

Hi - can you upload a video of what the actual weld pool is doing ? really not much can be judged from reading a digital readout fluctuate as they never remain constant even when everything is working fine - also is all that background noise just enviromental at your location or is it running off a generator ? if it is I'd be interested what the input is doing before diagnosing the welder - next is we can't see your manipulation or stickout which can have very strange results with synergic machines - has this unit always done this since you got it or has the fault developed over time - a lot of factors can cause synergic machines to freak out ! but a quick check needs to be made on all power connections both outside & internal to the machine especially earth - check earth clamp & good contact to work piece - check liner / feed rolls /spool brake / contact tip as any changing resistance or irregularity of wire feed can cause the machine to constantly try to compensate giving issues such as yours - hope some of that helps.

Hi noddybrian thanks for replying.

Good points you raise. I shall try to stick my phone in the welding helmet and get some footage of my welding style and hopefully show the surge issue.

Stick out is between 1/2 inch and 3/4 inch. I get that the longer the stick out the greater the resistance/voltage drop from contact tip to arc. I replaced the liner recently but the issue still occurs. Infrequently I might add.

That constant noise in the back ground is a 20ft freezer container running pretty much all day. Gotta have the ear pluggers in just to dull the constant drone of the thing. Gets old after a while.

Will have to borrow a sparkies/electricians clamp on multi meter to test what the input voltages are when in use. The numbers should be 230/250V @ 15A. Should that is. The power is coming from a large facility and the power supply in the area is notorious for fading in and out. I don't have lights where I work so I have no other indicator of power fluctuations, only the welding when it seems to act up.

As part of any troubleshooting excercise I should take it to a good known power source and try it out there.
